Fasteners Etc., Inc. supplies stainless-steel hex cap screws in 18-8 or 304 and 316 that meet industry standards for ASTM F593, offering minimum tensile strength of 90,000psi. Stainless-steel hex cap screws can be identified by the head markings, fastener manufactures will stamp the grade designation, at a minimum. Visually, a stainless-steel bolt will offer a bright, silver finish that would shine more so than a zinc plated counterpart. And lastly, a standard stainless-steel bolt would fail a magnetic test.
Those bolts made of 18-8 or 304 stainless-steel are ideal for many environmental conditions, offering corrosion resistance to moisture and some chemical environments. For projects that require superior corrosion resistance, consider the higher grade of stainless steel 316 hex cap screws. These bolts offer a longer service life resulting in a higher initial cost, but they will often show cost-savings in the long run. The 316 stainless steel bolts are best suited for harsh or corrosive environments such as exposure to saltwater and chemical agents.
