Customer Reviews (4.8 / 5 · 5 reviews)

Jason ★★★★★

Had to rebuild a piece of equipment on the farm and these bolts seated perfectly right out of the box—no rough edges or burrs. The class 10.9 steel feels solid, and the hex head gave my socket a good grip without rounding, even at full torque.

Claire ★★★★★

The threads are clean and the hex head sits flush in a 24mm socket—no wobble. Installed four to hold a steel bracket to a concrete anchor plate and they torqued down without stripping. Solid purchase for the price.

George ★★★★★

Needed some heavy-duty fasteners for a shop press rebuild and these M20s proved their strength right away. The fully threaded shank grabbed cleanly and the hex head gave my socket a solid bite without any rounding.
