Stainless steel bolts usually refer to steel bolts that have the ability to resist corrosion from air, water, acid, alkali salt or other media.

Stainless steel bolts are generally not easily damaged, durable, and can be used in environmental protection equipment, medical equipment, communication equipment and other fields.

Although some steels based on alloy composition have rust resistance, they are not necessarily acid resistant. Acid-resistant steels usually have rust resistance.

In people’s daily life, the stainless steel often referred to is also austenitic stainless steel.

According to the type of stainless steel bolts, it can be divided into stainless steel hexagon head bolts, stainless steel hexagon flange bolts, stainless steel square head bolts, round head (square or neck) bolts, countersunk (square or neck) bolts, and T-slot bolts , Stainless steel live joint bolts, stainless steel anchor bolts and other types.

The following will specifically talk about the respective uses of these types of stainless steel bolts.

Stainless steel grade head bolts are the most widely used type of bolts. Grade A and Grade B bolts are used for important occasions, requiring high assembly accuracy, and subject to penetrating impact, vibration or alternating mutation.

The thread on the bolt is generally coarse thread. The self-locking of ordinary threaded bolts in West Asia is better.

The main general bolts are partial threads. Full threaded bolts are mainly used for bolts with nominal lengths and required threads. Occasions.

The bolts with holes and reamed holes can accurately fix the mutual position of the connected parts, and can withstand the shear and extrusion caused by the transverse force.

The head of the stainless steel hexagonal flange bolt consists of two parts: the hexagonal head and the flange surface.

The “ratio of the supporting area to the stress area” is greater than that of the ordinary hexagonal head bolt, so the bolt can withstand higher pre-tightening force and prevent loosening The performance is also better, so it is widely used in automobile engines, heavy machinery and other products.
