Partially Threaded Steel Hex Head Cap Screw-3/4-10 x 3-3/4 in

This industrial-strength steel screw is made with a coarse thread and a zinc finish—it's ideal for heavy-duty applications like construction and manufacturing, where you need to attach two pieces of metal together quickly and securely. The Grade 5 rating means it can withstand heavy loads without breaking or bending, so it's perfect for securing beams in place or attaching large equipment to columns.
