M22-2.5 X 40mm 육각 머리 캡 나사 | 8.8급 강철 무도금 | 전체 나사산 (20개/팩)

Got these for a repair on some heavy shelving and they drove in smoothly without stripping. The hex head seats perfectly with a socket, and the fully threaded shank gave a solid bite. Worked exactly as needed for the job.

Had to torque these down on a heavy equipment jig and the hex head gave my socket wrench a solid bite without any rounding. The full threading really helped me get a tight hold in a deep hole. Exactly what I needed for the job.

Hex head fits my socket set perfectly, no slippage even torquing them down tight on the press frame. The 40mm length was just right for this job, and all twenty arrived clean with no burrs.
