Besides being versatile, type 304 stainless steel fasteners offer an economical alternative to other stainless steel. This is a grade 8 hex cap screw. These fasteners are ideal of use where there is exposure to chemicals and other types of corrosive products such as chloride which tends to cause pitting. For example, 410 SS has a low alloy content, meaning that there are fewer materials added to its composition, resulting in a higher carbon content. As such, 316 is recommended for use in coastal regions where there is an increased salt content, or in areas where there are higher levels of pollution or corrosive chemicals, particularly chloride. If a bolt is stainless steel, we recommend replacing with stainless steel. So, silicon bronze is composed of copper, silicon, and other alloys: tin, zinc, iron, magnesium, which makes them corrosion-resistant for marine and freshwater applications and they're used in electrical panels as I mentioned to you. For this reason, 304 SS products are more popular among consumers. So if you really want total non-magnetic there's aluminum and that's basically my demonstration of showing you that stainless steel, depending upon how it's been treated, becomes magnetic.

The following chart describes the situations in which a fastener of a particular material can be installed into a surface of a particular material. This chromium creates a surface film that resists oxidation. Now I'm going to show you a nut, which is stainless 316. It is important to remember that even the salt in the air near a body of salt-water can do damage to dry applications, so 316 is the material of choice. These are also, just so you know, plain and oiled finished. 304L Stainless Steel Bolts/ s30400 bolt Torque Chart, Other Types Of Stainless Steel 304 Fasteners, SUS304L Stainless Steel Stove Bolts Exporter, AISI 304L Stainless Steel Anchor Bolts Stockist, 304L Stainless Steel Tower Bolts Wholesaler, UNS 30409 Stainless Steel U Bolts Supplier, Stainless Steel 304 Fasteners Specifications, SS 304 Fasteners Price List/ SS 304 Nut Bolt Price List, Size Chart of AISI 304L Stainless Steel Nuts, Dimensions of SS UNS S30400 Heavy Hex Nuts, Other Types Of SUS304 Stainless Steel Fasteners, Chemical Composition of 304 Stainless Steel Fasteners, 304 Stainless Steel Fasteners Equivalent Grade, Stainless Steel 304 Fasteners Mechanical Properties, AISI 304 Stainless Steel Fasteners Physical Properties, Stainless Steel 304 / 304H / 304L Fasteners, Stainless Steel 304 / 304H / 304L Washers, Stainless Steel 316 / 316H / 316L Fasteners, DIN, ASTM, BS and all International Standards. Aluminum should never be used with Stainless Steel, galvanic corrosion may occur. As far as grades go, I was showing you the grades, most plain bolts, other than structural, will have the grade 8 markings on them. The ASTM A193 specification includes fasteners of types B7, B8 and B8M with their different class variations. Grade A and Grade 2 are the most common grades of zinc plated alloy steel. Stainless steel is used primarily for long lasting applications, due to its corrosion-resistant nature and durability. Asiad Steels are ss 304 nut bolt manufacturer which are demanded worldwide. So I'm gonna show you a couple of heads.
I'm Bob and today we're going to talk about different grades and types of bolts. Fasteners made of nickel-copper alloys have a tensile strength of roughly 80,000 PSI while fasteners made of nickel-copper-aluminum have a tensile strength of around 130,000 PSI. The SS 304 Hex Bolts are some of the preferred fasteners due to their geometrical strength and ease of application with tools. 307A is the indication of the strength of the bolt. The 304 material has 205MPa minimum yield strength and 515MPa minimum tensile strength. Brass has no magnetic field to it at all. c ) 316 Stainless Steel: Office 2: +91-22-66644059, Plot No 02 Ground Floor, Gardanchs LTD Bhajekar Street, Opp 11 Khetwadi Main Road, If it had no manufacturers marking, you would just see those six slashes and that would indicate to you that you have a grade eight bolt. Typically, you'll see initials on there, this is an lb okay? Body Diameter - There may be a reasonable swell or fin under the head or die seam on the body not to exceed the basic bolt diameter by the following: Weight in kgs. The information from this chart is derived from the MCA technical document, "Fastener Compatibility with Profiled Metal Roof and Wall Panels". Bob: Welcome back to Albany County Fastener - Fasteners 101. They are corrosion-resistant and durable. Zinc Plated Alloy Steel is a common material that fasteners are manufactured in. Harder than 18-8 stainless but with less corrosion resistance, 410 stainless is commonly used to make roofing screws, siding screws and self-. Grade 304 stainless steel. When you go out and you're looking for a grade 5 bolt, you're always looking for the three slashes on the bolt. It is important for contractors to choose the correct material for their fasteners based on their job site environment. BIG BOLT NUT is a manufacturer & exporter of Bigger Diameter Bolt and nuts.

Common applications of 316 stainless fasteners include use on boats, docks, piers, and pools.
So, because of the hot dip galvanizing process, (the zinc) is so thick they have to adjust the threads, so they'd properly coat the thread. Approximate weights in kilograms (Kgs) each, Office 1: +91-22-66343169 Socket products: These are excellent for use where corrosion resistance is required or where you have limited space. Brass conducts electricity and is also a good conductor of heat. Stainless Steel UNS S30403 Machine Screws is often used in food processing equipment, particularly in beer brewing, milk processing, and wine making. Stainless alloy resists oxidizing and rusting, however it can tarnish over time. 304L This is a lower carbon version of type 304 which is slightly lower in strength but has increased corrosion resistance and welding capacity. This is a large grade 8 bolt and there you can see the markings. This is an aluminum rivet. 304 ss bolts are from T 300 series authentic stainless steel bolts. It is often used in pipes, weather stripping, trim, radiators, musical instruments, and firearms. I have here a grade 5 bolt.

This grade of fasteners is economical on account of the stainless steel having good corrosion resistance properties towards a broad spectrum of general and localized corrosive media. Finish is equivalent in strength to Grade 8 but without the yellow color. That will help to pick the right material. Another difference between the 304 and 316 is the cost of the material. You can see all these have heavy magnetism. So I have here some nuts, a lock washer, dowel pin, a hex cap screw with a tap bolt, all of these items here are 316 stainless and you may be able to see that. (17%-19% Chrome, 8%-10% Nickel, .12% Maximum Carbon) - This grade has been developed specifically to improve the cold heading qualities of 18-8. You'll see that marking on there: 316. The 304 Stainless Steel Dowel Pins are another type of the fasteners. With constant improvement in quality we have been able to excel in the manufacturing process for the above steels and their respective grades. b ) 305 Stainless Steel: This grade 2 bolt has no markings, no slashes at all. Last Updated on July 1, 2020 by Marsh Fasteners. There is brass out there that they do use lead in. This is a hot dip galvanized hex cap screw. Steel bolt are high strength steel alloy and are strongest commercial quality bolts. While it is still corrosion resistant, it is not recommended for areas where corrosion is likely to occur. These typically have to have thicker threads. We offer the lowest minimums in the industry, and sell by the piece or in bulk - you buy only the fasteners you need! JavaScript seems to be disabled in your browser. Brass again used in plumbing, hot water, these typically have no heavy strength to them at all. You cannot use a zinc nut with a hot dip galvanized nut, it just won't go on properly and you're going to have problems. It is important to remember that even the salt in the air near a body of salt-water can do damage to dry applications, so 316 is the material of choice. Untreated alloy steel fasteners are black. The specifications vary according to the IS, BS and ASTM standards. There is very little overall difference in corrosion resistance among these 18-8 series types. in India, we have 2 factories with a total covered area of over 100,00 sq. Grade 8 zinc plated alloy steel bolts are thru-heated and thru-hardened with a CR+5 zinc plating. Head markings on a bolt are a quick way to determine bolt grade. Besides being versatile, type 304 stainless steel fasteners offer an economical alternative to other stainless steel. This is a grade 8 hex cap screw. These fasteners are ideal of use where there is exposure to chemicals and other types of corrosive products such as chloride which tends to cause pitting. For example, 410 SS has a low alloy content, meaning that there are fewer materials added to its composition, resulting in a higher carbon content. As such, 316 is recommended for use in coastal regions where there is an increased salt content, or in areas where there are higher levels of pollution or corrosive chemicals, particularly chloride. If a bolt is stainless steel, we recommend replacing with stainless steel. So, silicon bronze is composed of copper, silicon, and other alloys: tin, zinc, iron, magnesium, which makes them corrosion-resistant for marine and freshwater applications and they're used in electrical panels as I mentioned to you. For this reason, 304 SS products are more popular among consumers. So if you really want total non-magnetic there's aluminum and that's basically my demonstration of showing you that stainless steel, depending upon how it's been treated, becomes magnetic. The high mechanical properties come through the chemical composition with carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel and nitrogen. Our price is applicable in Qatar, UAE, Malaysia, Indonesia, Singapore, Thailand, Zambia, Azerbaijan including West african countries and Middle East countries. In addition, many of our cladding fasteners for rainscreen systems and panel screws are offered with both 304 and 316 to accommodate a diverse range of environments, including highly corrosive conditions.
