M10 x 80mm 肩式螺絲（內六角頭）| 內六角頭 | 內六角驅動 | 合金鋼（25入/包）

Ground the shoulder on these M10s before pressing them into my linkage arms—the fit was true to spec, no slop at all. The hex socket drive took the torque without stripping, and the 80mm length gave me just enough thread for a locknut. Definitely ordering another pack for the next build.

Installing these as hinge pins on a small gate was way easier than I expected, the machined shoulder provides a perfectly smooth rotating surface. Threads cut cleanly into mild steel without binding, and the hex socket held the driver securely. Exactly what I needed for a high-wear pivot application

I needed a sturdy pivot for a custom jig I’m building, and these M10 shoulder screws slid into the bearing bores with zero play—the precision-ground shoulder is exactly as advertised. The hex socket drive gave me solid torque without stripping, and the 80mm length was perfect for my setup.
