Customer Reviews (4.8 / 5 · 5 reviews)

Ellie ★★★★★

These cup point screws bite into the shaft firmly and the 3-1/2" length was exactly what I needed for a heavy-duty locking application. The alloy steel feels tough and the hex drive held up well under my torque wrench.

Ella ★★★★★

I needed a longer set screw for a custom jig, and the hex socket drive made tightening in a cramped spot surprisingly easy. The cup point really digs in—these aren't budging once torqued down.

Edward F. ★★★★★

These set screws held solidly after I tightened them in a tight mounting bracket. The cup point really digs into the shaft without slipping. Exactly what I needed for a permanent alignment fix.
