Penelope ★★★★★

Picked up a pack for repairing a jig at work, and the black oxide finish keeps them from rusting in my damp tool box. The 6-inch length was exactly what I needed, and the hex drive seated perfectly with my standard Allen wrench. Solid fasteners for the price.

Violet W. ★★★★★

Needed longer hex bolts for a precision fixture and these 3/8-16s threaded in smoothly with no binding. The black oxide finish seems durable and should hold up well in my tooling setup.

Madison ★★★★★

Bought these for a jig I was building and the 6" length was exactly what I needed. The hex socket drive made installation easy with a standard Allen key, and they threaded smoothly without any binding.
