Stainless Steel Bolt

Stainless steel bolt normally refers to a bolt fighting against air, water, acid, alkali salt or other media corrosion, widely applied to all walks of life. Our company produces it in accordance with different shapes, which can be divided into multiple types of bolt, like hex type, hex socket type, countersunk type, cup head type, crosshead type, flat head type and more.

This series of stainless steel bolt adopts stainless steel of A2 and A4 grade, also called SUS 304 and SUS 316 grade. Among them, A2 stainless steel is mainly used for producing ordinary stainless product, while A4 type aims at manufacturing the bolt with high corrosion resistance, the strength grade of which falls into 50, 70 and 80. In particular, A4 material is more excellent in atmospheric corrosion resistance and high temperature resistance under worse corrosive environment than A2 material.

We provide the product of metric series and US made series, with the specification of M6 to M64 and 1/4" to 5-1/2" respectively. The former chooses the standard of DIN, BS, JIS and AS, while the latter uses ASME and AS. In short, our customers can purchase flexibly to meet the requirement of the equipment used.
