M8 x 35mm 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (25個/包)

Installing these as axles for a small assembly project, I was impressed by how perfectly the shoulder fit into the bearing bore — no wobble at all. The hex socket drive made torquing them down quick and secure.

Used a few of these as pivot pins in a custom jig, and the hex socket drive made installation a breeze with my Allen key. The shoulder is smooth and consistent across all 25 pieces.

The precision-ground shoulder is dead-on at 8mm, so these spin smoothly as axle pins without any wobble. I used them for a jig pivot and the hex drive seated cleanly every time I torqued them down.
