Benjamin ★★★★★

I needed a high-torque set screw for a stubborn machinery adjustment, and these cup point socket screws held fast even under serious wrenching. The hex socket drive made installation a breeze in that cramped space. Exactly what I was hoping for.

Grace ★★★★★

Finally got these in for a heavy clamping jig I'm building, and the 3" length gives me plenty of grip through thick brackets. The cup point really digs into the metal without slipping, and the hex drive took some serious torque without rounding.

Violet C. ★★★★★

I was worried about stripping the hex socket drive in a tight spot, but these cup point screws seated perfectly. The 18/8 stainless steel feels solid and rust-resistant, exactly what I needed for an outdoor project.
