304 & 316 Stainless Hex Cap Screws

Hex cap screws have integrated washers and heavy-duty heads, making them ideal for equipment installations, machinery repairs, and other industrial applications featuring tapped holes. Stainless steel hex cap screws are premium options for tensile strength, corrosion resistance, and moisture resistance.

At Brazos Fasteners, we have decades as a 304 & 316 stainless steel hex cap screw supplier. We deliver high-quality parts to exacting specs. Contact us to see all of the available options for SS hex cap screws.

Stainless Steel Options

As a trusted stainless steel hex cap screw distributor for U.S. and international businesses, we offer a few options for stainless steel cap screws.

304 (A2) Stainless Steel hex Cap Screws: Hex cap screws made with 304 SS provide excellent corrosion resistance, tensile strength, and durability. This steel alloy features nickel (8-10%) and chromium (17-19%). It’s common in food service and durable goods manufacturing.

The two most popular stainless steel fasteners are 18-8 (300 series) and 400 series. Of the two, the 18-8 series has proven to be the best for corrosion resistance and ductility.

316 (A4) Stainless Steel Hex Cap Screws: Standing up better in saltwater and caustic environments, 316 SS is the gold standard of corrosion resistance for industrial applications. This material features more nickel (10-14%) and molybdenum (2-3%), giving it high temperature tolerance.

A quick tip when using stainless bolts and hardware, using an anti-seize lubrication to help reduce friction during installation is a common practice to prevent stainless steel from galling. We also stock these anti-seize lubricants.

Benefits of Stainless Fully Threaded Cap Screws

Stainless steel fully threaded cap screws require minimal maintenance. They stand up to ages of use without problems.

Other materials, such as galvanized steel alloys, have a corrosion-resistant layer on top of high-strength steel. Eventually, this layer can wear away or receive damage. In contrast, stainless steel provides corrosion resistance at a core level.

Even in the case of scratches, impacts, demanding operating environments, and exposure to the elements, these high-performance hex cap screws maintain their moisture- and corrosion-resistant profile.
