Joseph M. ★★★★★

The hex head on these M6 cap screws is a solid improvement over the standard Phillips I was using, and the 10.9 steel feels plenty tough for assembly work. The fully threaded shaft lets me set the depth exactly where I need it, and getting 3,300 in one pack means I'm set for a while.

Richard U. ★★★★★

I needed a large batch of fasteners for a series of jigs, and these cap screws came with consistent threading and a clean hex socket that didn't strip under torque. The 3300-count package saved me multiple trips, and the 10.9 steel feels sturdy enough for heavy machinery use without any rust worries

Jacob P. ★★★★★

Used these to assemble a steel rack in my garage, and the 10.9 grade held tight without any stripping. The hex heads fit my socket perfectly, and having 3300 pieces means I’m set for plenty more projects.
