M12-1.5 x 40mm 육각 머리 볼트 | 클래스 8.8 스틸 무도금 | 풀 나사 (100개/팩)

Bought these for a jig I'm building and the full threading made alignment way easier than dealing with partial threads. Hex head sat flush with my socket wrench, no stripping even at decent torque.

Threaded all the way to the top—exactly what I needed for mounting a heavy bracket, and they drove in straight without any binding. The hex head fit my socket snugly too.

Used about half the box rebuilding a jig at work and the hex heads held up perfectly under a torque wrench. The full threading on these 40mm bolts made alignment a breeze, and not a single one had a burr on the threads. Solid purchase for the price.
