Stainless Steel Machine Bolts Offer Strength and Corrosion Resistance
West Marine offers hex head machine bolts, also known as cap screws or hex bolts, in a variety of lengths, diameters and thread types, including SAE and metric. Nearly all are made of 18-8 stainless steel, which provides great strength and corrosion resistance. In addition to stainless steel bolts, West Marine offers a limited number of machine bolts made of silicone bronze which when used to fasten bronze parts together reduces the chance of galvanic corrosion. Bolt diameters range from 1/4" up to 1/2". Lengths range from 1" up to 10", depending on the diameter.
