HOLO-KROME 09027 10mm x 60mm 內六角肩螺絲 | 內六角頭 | 六角驅動 | 合金鋼熱處理黑色氧化 (25/包)

The hex socket drive made installation a breeze with my torque wrench. The precision ground shoulder provides a noticeably smooth bearing surface for my small axle project. Exactly the consistency I needed across all 25 pieces.

I needed a precision bearing surface for a custom jig, and these shoulder screws work perfectly. The 60mm length and ground shoulder are exactly what I was looking for to create a smooth pivot point.

The fit on these shoulder screws is spot-on for my jig setup—the 10mm shoulder slides through the bushing with zero play. That black oxide finish handled a few drops of oil without smudging, which is nice.
