Ruby ★★★★★

These set screws cut threads cleanly into the pre-drilled holes on my milling vice, and the hex socket drive gave me plenty of leverage to really torque them down. The alloy steel feels solid, and the cup point grips the shaft firmly without slipping. Exactly what I needed for a secure hold.

Victoria U. ★★★★★

The cup point tip seated flush without any stripping, which surprised me for the price. These alloy steel screws handled my high-torque driver perfectly in a tight machinery corner. Solid buy for the quantity.

Julian D. ★★★★★

The hex socket drive on these screws made tightening in that cramped spot on my jig a breeze. They held firm without any stripping, and the cup point seated nicely against the wood. Exactly what I needed for a durable build.
