Joseph W. ★★★★★ Oct 23, 2026

Used these to secure a heavy-duty jig on a drill press table, and the 4-inch length gave me plenty of bite through thick steel. The hex socket drive made tightening them down a breeze, even in an awkward spot.

Nicholas ★★★★★ Oct 21, 2026

I had to crank these down pretty hard in a tight CNC fixture, and the hex socket drive didn't strip at all. The flat point bit into the surface exactly as needed—solid hold.

Leo Z. ★★★★★ Oct 20, 2026

I needed to adjust a heavy jig in a tight corner, and these 4" flat point screws let me get the hex driver in without any awkward angling. The alloy steel feels solid and the threads cut cleanly into the metal plate.
