Chloe F. ★★★★★

The threads cut cleanly and started by hand even in tight holes. These hex cap screws feel solidly made and should hold up well under load.

Harper Q. ★★★★★

Used them to bolt down a heavy baseplate on the shop floor and they seated perfectly with a wrench, no stripping even at full torque. The 7/8-9 thread took the partial thread engagement fine, and the pack of 30 gave me plenty of spares for the next job.

Joshua I. ★★★★★

The threads cut clean and the partially threaded length gave me just the grip I needed on a heavy equipment frame. The B7 alloy steel feels dense and solid, no flex when torqued down. These are the ones I'll grab again for the next assembly.
