M10-1.5 X 130mm 六角穴付きボルト | クラス10.9 スチール プレーン | 部分ねじ (50本/パッケージ)

The partial threading on these bolts makes aligning them into a tapped hole so much easier than a fully threaded one. I used them to secure a heavy motor mount, and the 10.9 grade feels rock solid.

My torque wrench clicked right on spec when tightening these to 90 ft-lbs on a piece of mining equipment, and the partial threading made alignment easy. They drove in smoothly without any stripping, even with a 12-point socket.

Needed these exact partially threaded M10 bolts for a heavy equipment frame repair and the class 10.9 steel feels seriously sturdy under the wrench. The hex head gave my socket a solid grip without any rounding.
