M12 X 75mm 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (25個/包)

The precision-ground shoulder on these M12 screws made alignment much easier than I expected when setting up a jig. They slide smoothly into the bearing housing without any binding. Solid hardware for the price.

Used a few of these as pivot pins for a small fixture I’m building, and the socket drive made torquing them into tight spots way easier than I expected. The precision-ground shoulder slid into the bearing bore with zero play, which is exactly what I needed for smooth rotation.

The precision-ground shoulder on these screws is noticeably smooth—they slide into bearings without any binding. I used them as axle pins on a custom jig and they held up perfectly under load. Exactly the quality I needed for this build.
