Customer Reviews (4.6 / 5 · 5 reviews)

Timothy ★★★★★

Delivery was quick and the bulk pack is perfect for my ongoing assembly projects. The class 8.8 steel feels robust enough for the small machinery I'm working on, and the hex heads hold a socket wrench well without stripping.

Harper ★★★★★

These little M3 bolts are perfect for mounting brackets on my 3D printer frame, and the Class 8.8 steel feels solid under the wrench. A full 1200-pack for under twenty bucks means I won't need to reorder for years.

Brian ★★★★★

Used these for a small robotics project and the hex heads gripped nicely with a ball-end driver. The 1200-count pack will probably last me years, but the consistent threading made assembly go smoothly.
