M16 X 20mm 소켓 숄더 나사 | 소켓 헤드 | 소켓 드라이브 | 합금강 (25/팩)

Used a pair of these as pivot pins for a heavy jig I built, and the hex socket drive made installation a breeze. The alloy steel feels solid and the shoulder is perfectly smooth. Exactly what I needed for a precise bearing surface.

The precision-ground shoulder made setting up a hinge pivot feel almost too easy—no filing or fitting needed. Hex socket drive seated cleanly with my Allen key. Solid alloy steel, exactly what I needed for a bearing surface.

Finally, a shoulder screw with a true M16 thread that actually fits my bearing housings without any filing. The precision-ground shoulder made aligning the parts in my assembly line fixture effortless.
