Fasteners Etc., Inc. supplies metric stainless-steel hex cap screws in A2 and A4 that meet industry standards for Din and ISO, offering minimum tensile strength of 90,000psi. Stainless steel hex cap screws can be identified by the head markings, most 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 A2 or 304 stainless-steel are ideal for many environmental conditions, offering higher level corrosion resistance to moisture and some chemical environments. For projects that require superior corrosion resistance, consider the next grade of stainless steel A4 or 316.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 A4/316 stainless steel bolts are best suited for harsh or corrosive environments such as exposure to saltwater and chemical agents.
