Customer Reviews (4.6 / 5 · 5 reviews)

Charlotte ★★★★★

Had to replace some original mounting hardware on an older project and these SEMS screws saved me time since the washer is already captive. The zinc plating gives them a nice even finish and the Phillips drive seated cleanly without any cam-out.

Violet ★★★★★

Finally, a small machine screw that actually holds tight without stripping. The zinc plating looks consistent across all 1000 pieces, which saves me time sorting through rejects.

David U. ★★★★★

The zinc plating is nice and even across all 1000 pieces, so they should hold up well in my shop. The cone point seats perfectly into the pilot holes on the aluminum brackets I'm assembling, and the Phillips head drives clean without stripping.
