Solid 316 Stainless Steel Machine Screws / Bolts
Most retailers will sell stainless steel machine screws and not name the alloy. "Stainless Steel" encompasses a large variety of alloys, and you'll often find that an inferior, and cheaper to produce "Stainless Steel" is what's sold when the alloy goes unnamed. We only carry Type 316 Stainless Steel Machine Screws, and won't sell you anything less, as it's not what we would use on our boat.
316 (A4) Stainless Steel is far more corrosion resistant than it's 304, A2, or 18-8 Stainless Steel counterparts, and should be your go-to alloy in a marine stainless steel application. The additional nickel and molybdenum in 316 stainless adds additional corrosion protection that is necessary in a marine or otherwise corrosive environment.
These oval head 316SS machine screws, or machine bolts come in imperial sizes, have a countersunk (CSK) head, and are available in phillips drive. They'll polish up to a mirror finish if desired.

Fast Service. Harder to find 316 Stainless.
I purchased the Oval Head Stainless Steel Machine screws. They arrived in a timely manner and were of good quality. Would purchase again.
Fair Wind stocks the high quality marine fasteners that are very hard to find anywhere else - and is willing to sell the quantity you need, rather than box quantities. Communication is good, shipping is prompt, and overall the service is excellent.
Great resource for 316ss fasteners, not the inferior ss that west marine sells.
