Half Thread SS304 SS316 Stainless Steel Hex Head Screws High Holding Power DIN931
1. Description:
Stainless Steel Hexagon Bolts (DIN 931)
Stainless Steel Hexagon Bolts to DIN 931, also known as Hex Head Cap Screws are part of our bolting range featuring a hexagon head that is fastened using either a spanner or socket. The machine thread means that they are suitable for use with either a nut or in a pre tapped hole. They are partially threaded with a plain portion on the shank leading up to the head.
Stainless Steel Hexagon Bolts are stocked from M3 to M64 in either A2 or A4 stainless steel as standard in the lengths listed below, with next day delivery available. We can also offer Hexagon Bolts in UNC, UNF, BSW and BSF as well as a wealth of other materials such as steel, brass, aluminium and titanium.
We can also manufacture non standard special thread diameters, lengths, pitches and plain portions so if you can’t see the item you are looking for we can still help!
2. Specification Requirements:

3. Applications:
Stainless steel screws are widely used in machinery , petrochemical , communication , chemical industry , construction industry , electric power , textile , sports equipment , paper making , sewage treatment , ship , automobile and other industries . With the improvement of domestic economic living standard , the application scope of stainless steel screw will be more extensive .
Stainless steel screws, as the name implies, must be made of stainless steel screws and wire piers. After rubbing the screw thread. And stainless steel screws have a lot of properties related to stainless steel material. Considering the properties and organization of stainless steel. To understand the properties of stainless steel, so as to understand that stainless steel has anti-rust, anti-corrosion, high-temperature and other good mechanical properties. Then stainless steel screws of course have these good mechanical properties. With the material of stainless steel more and more excellent. Screw industry produced stainless steel screws on the mechanical properties of better and better. Rust prevention. Corrosion resistance, and high temperature and pressure is getting stronger and stronger.
Type 302 for machine-working screws and self-tapping bolts.
Type 304 is suitable for stainless steel screw processing by hot upsetting, such as long specification bolts and large diameter bolts, which may be beyond the range of cold heading process.
Type 305 is suitable for cold heading processing stainless steel screws, such as cold forming nuts, hexagonal bolts.
Both 316 and 317 contain Mo-alloy elements, so their high temperature strength and corrosion resistance are higher than those of 18-8 stainless steel.
