These stainless steel bolts are austenitic and non-magnetic. The carbon content is held to 0.08% maximum, while the nickel content is increased. Molybdenum of 3% is also added to the combination.

304 Stainless steel bolts

These bolts are austenitic steel possessing a minimum of 18% chromium and 8% nickel and a maximum of 0.08% carbon. It is a nonmagnetic steel which cannot be hardened by heat and must be cold-worked to obtain higher strengths.

18/8 Stainless Steel bolts

These bolts have 18% chromium and 8% nickel. The term "18-8" is used to characterize fittings made of 302, 302HQ, 303, 304, 305, 384, XM7, and other variables of these grades with close chemical compositions.

Button head stainless steel bolts

Button head stainless steel bolts are used in machine parts and clamping. The button head enables driving where there is not sufficient space for wrenches or sockets. These bolts also offer a bigger bearing surface and high strength.

Carriage stainless steel Bolts

A carriage stainless steel bolt has a domed or countersunk head and the shank is topped by a short square section under the head. The square section fits into the part being fixed, preventing the bolt from turning when the nut is tightened.

Hex Head stainless steel Bolts
