Customer Reviews (4.6 / 5 · 5 reviews)

Grace ★★★★★

I needed a strong, fully threaded fastener for a jig I was building, and the hex head on these made tightening with a socket wrench really easy. The metal feels solid, and 100mm was just the right length for my application.

William F. ★★★★★

I was worried about finding bolts strong enough for my conveyor repair, but these M42s with the full threading gave me a solid grip. The hex head made tightening with a socket effortless, and they’ve held up perfectly under daily load.

Michael ★★★★★

Needed heavy-duty bolts for a press frame repair, and these fully threaded M42 caps with the hex head drive fit the bill perfectly. The Class 8.8 steel feels solid and they threaded in smoothly without any binding.
