M8 X 8mm 內六角肩螺絲 | 圓頭 | 六角驅動 | 合金鋼 (50 / 包)

The precision-ground shoulder slides through my linkage holes with zero play, which is exactly what I needed for a smooth bearing surface. Hex socket drive made tightening them in tight spots a breeze, and all 50 arrived clean and consistent.

These work perfectly as pivot pins for a small jig I built — the precision-ground shoulder spins smooth and true inside a bushing. The hex socket drive makes installation a breeze with an Allen key, and the pack of 50 is great value for the quality.

These work perfectly as pivot pins for a small jig I built; the hex socket made them easy to install in a tight spot. For the price, getting 50 precision-ground shoulders in alloy steel feels like a solid deal.
