Nicholas U. ★★★★★

The hex socket drive on these 3/8-16 screws bites nicely on the Allen key without slipping, which made installing them into my jig fixture much smoother than with cheaper bolts. Alloy steel feels solid and the black finish seems durable enough for regular use on my tooling projects.

Aurora ★★★★★

Used these to build a new set of indexing fixtures for my mill, and they threaded perfectly into tapped holes without any binding. The hex socket drive made seating them in tight spots really easy. For the price per pack, the alloy steel quality feels solid.

Violet ★★★★★

Installed a batch of these on a heavy-duty fixture and the hex socket drive grabs perfectly without stripping. The alloy steel feels much more durable than the cheap stuff from the hardware store.
