M20-2.5 x 90mm 六角頭螺絲 | 8.8級鋼 普通 | 部分螺紋 (20顆/包)

The partial threading on these M20 bolts made alignment a lot easier when I was torquing them down. The hex heads sat snug in my socket without any wobble, and all twenty arrived with clean, uniform threads.

Threaded perfectly into the heavy equipment frame I'm rebuilding, the hex heads gave my socket wrench a solid bite without slipping. These class 8.8 bolts feel sturdy enough for serious torque, and the partial threading made alignment much easier.

Used these to secure a steel bracket onto a concrete base—the hex head gave my ratchet a solid grip, and the 8.8 steel held torque without stripping. Partial threading made alignment easy.
