Customer Reviews (5.0 / 5 · 5 reviews)

Matthew ★★★★★

Needed a bulk pack for rebuilding some jigs and these were exactly the right thread pitch and length. The flat head sits flush and the hex drive makes them easy to install with a standard Allen key.

Kevin ★★★★★

Swapped out some old machine screws with these for a jig assembly and the hex socket drive made installation a breeze. The flat head sits flush perfectly, and the stainless steel feels sturdy.

Henry J. ★★★★★

Popped one of these into my drill press jig and it seated perfectly with no wobble. The hex drive held up fine without stripping under my cordless driver.
