Customer Reviews (4.4 / 5 · 5 reviews)

David R. ★★★★★

Bought these for a fixture adjustment on a milling vise, and the knurled cup point gave me a positive lock without marring the surface underneath. Counted them out of the bag—exactly 250, all clean and ready to use.

Amelia Z. ★★★★★

These set screws are exactly what I needed for a stubborn indexing fixture on my mill. The hex socket engages perfectly, letting me torque them down firmly even in a tight spot.

Jason Z. ★★★★☆

The hex socket drive made snugging these into a tight spot way easier than I expected, and the knurled grip on the cup point gives extra purchase when setting. Only gripe is the packaging—a couple screws had minor scuffs, but the batch itself is solid for the price.
