Customer Reviews (4.4 / 5 · 5 reviews)

George L. ★★★★★

Was hunting for a reliable fastener for a jig I'm building and these hit the mark. The hex socket drive grips the Allen key perfectly, no stripping, and the 140 count means I've got plenty of spares for future jobs. Alloy steel feels solid and the flat heads sit cleanly without snagging.

Ella S. ★★★★★

The hex socket drive on these M4 screws fits my T-handle perfectly, no stripping even after tightening a few jig fixtures. The alloy steel feels sturdy, and the flat head sits flush in my aluminum workpieces. Exactly what I needed for precision assemblies.

Thomas W. ★★★★☆

The flat head sits perfectly flush in my jig, which is exactly what I needed for a clean assembly. The 140-piece pack is great value for the price, though the alloy steel feels a bit harder than I'd like when hand-tightening.
