M14-1.5 X 45mm 六角頭螺絲 | 等級10.9 鋼 素面 | 全螺紋 (250個/包)

The threads are cut clean with no burrs, and the 10.9 steel feels plenty rigid when I torque them down. For a full box of 250, the price breaks down nicely for shop stock.

Fits perfectly in my impact driver with the right socket, and the class 10.9 rating means I can torque them down without stripping or snapping. Exactly what I needed for securing heavy equipment brackets.

I was worried about the 250-count package being mostly waste, but every single screw threaded cleanly into my jig without any burs or hangups. The hex head really bites into a socket wrench for a solid grip when torquing them down tight.
