Need heavy-duty fasteners for machinery, automotive, or industrial projects? These IIVVERR shoulder bolts (also called shoulder screws) are made from tough alloy steel with a black oxide finish for corrosion resistance. Each bolt has a 1/2\ diameter smooth shoulder that's 2\ long—perfect for acting as a pivot, spacer, or locating pin. The threaded portion is 3/8\-16 UNC (coarse thread), about 0.59\ long, with a hex socket drive for secure tightening. Grade 12.9 rating means they're super strong and reliable. The shoulder helps reduce rotation and provides precise alignment in assemblies. Set includes 5 pieces. Great for applications where you need a smooth bearing surface combined with threaded retention. Just grab your hex key or bit and you're ready to install.
