As with all of our fasteners at Fair Wind Fasteners our 316 Stainless Steel Hex Bolts are curated to be the finest quality available. These marine grade stainless steel bolts with stay rust and corrosion free much longer than their 304 counterparts that are commonly available.
These UNC course imperial threaded hex bolts meet ANSI B18.2.1 and are a guaranteed 316 stainless steel alloy, not some mystery "Stainless" that will leave rust streaks running down your project in no time.
Length is measured from the bottom of the hex head to the end of the bolt. Smaller sizes are fully threaded, with larger sizes being partially threaded. Specific thread lengths for each bolt we sell can be found below.
