M12 X 55mm براغي ذات كتف بمقبس | رأس مقبس | محرك مقبس | سبيكة فولاذ (25/عبوة)

I needed a shoulder screw for a pivot application and these M12s worked perfectly — the precision-ground surface is noticeably smoother than standard hex bolts. The socket drive made installation effortless with a hex key.

The precision-ground shoulder on these screws is noticeably smooth, making them perfect for a small axle in a homemade hinge. They seated perfectly with a 10mm socket bit, no wobble at all. Happy with this pack of 25 for custom hardware projects.

I used these as pivot pins for a jig I'm building and the hex socket drive made installation a breeze. The shoulder is really smooth and consistent across all 25 pieces.
