Most of the standard strength fasteners are made of "18-8" (300 series stainless steel having approximately 18% chromium and 8% nickel). The metric designation is A2. The strength of these fasteners is between Grade 2 and 3.
Stainless steel is a fairly soft metal and for this reason it tends to gall. Always use Anti-Seize or a similar product when working with stainless steel fasteners! If you have never had a stainless fastener gall on you before, it's not fun. When a fastener galls, it seizes.
DO NOT use standard strength stainless fateners on critical race car applications such as rear ends, steering joints or motor mounts as well as on OEM/aftermarket braking or suspension systems.
We offer a full line of ARP 170,000 psi high strength "grade 8" stainless fasteners in 12pt and 6pt heads that work very well on these applications up through 7/16" diameter. Always refer to the application guidelines of the original manufacturer. |
