Avery I. ★★★★★

The hex socket drive made installation really easy with my standard Allen wrench set, and all 200 screws in the package had consistent, clean threads. Perfect for building my new drill press jig.

Miles ★★★★★

I used a handful of these to secure a heavy-duty fixture on my mill table, and the hex socket drive made tightening them in tight spots a breeze. The alloy steel feels noticeably tougher than the standard bolts I’ve been using, and the 3-1/2" length was exactly what I needed to reach through a thick

Michael ★★★★★

Needed a longer bolt for a tooling jig I'm building, and the 3-1/2" length worked perfectly with the alloy steel providing a solid feel. The threads were clean and caught easily without any cross-threading.
