Customer Reviews (4.8 / 5 · 5 reviews)

Evelyn V. ★★★★★

The threading is clean and consistent on all 25 bolts, so my ratchet engaged smoothly every time. These M18 screws feel solid enough for heavy equipment assembly without any worry about stripping.

Jason ★★★★★

The hex head design gave my socket a solid grip without slipping, which made tightening these 10.9 steel screws on my shop press much easier. They threaded smoothly into the tapped holes and feel sturdy enough for heavy use.

Madison W. ★★★★★

The 10.9 grade steel feels solid when torquing these down—no stripping or rounding like cheaper bolts. The zinc plating looks clean and hasn’t shown any rust yet after a week on my equipment jig.
