Customer Reviews (5.0 / 5 · 5 reviews)

Adam ★★★★★

The threading was clean and consistent on every bolt, making assembly smooth on my press jig. The zinc coating looks evenly applied and should handle my shop environment well.

Scarlett G. ★★★★★

Used these on a conveyor frame repair and the 280mm length was perfect for the deep bolt-through we had. The zinc plating held up fine against the shop grime, no rust spots after a week of assembly work. Partial threads let us torque them down properly without binding up.

Miles ★★★★★

The hex head gave my socket a solid grip, and the zinc finish on the 10.9 steel looks clean even after a week of sitting in a damp toolbox. Perfect length for the bracket I was mounting.
