Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

These M4 low head screws fit perfectly into tight clearance spots on my jig where a standard cap screw wouldn't clear. The hex drive bites well without stripping, and having 400 in one package means I won't need to restock for a while.

Edward ★★★★★

Installing these into a precision fixture, the hex drive bit seated perfectly without any slippage. All 400 screws in the pack have clean, consistent threads and no burrs on the heads. Perfect for the jig I’m assembling, and the low-profile head clears the sliding components easily.

Carter U. ★★★★★

Used a dozen of these on a jig I'm building, and the low head profile is perfect for tight spaces where a standard cap screw wouldn't fit. The hex drive engaged cleanly without stripping, even with my cheap Allen keys.
