براغي كتف بمقبس 5/16" × 7/8" | رأس مقبس | محرك مقبس | فولاذ مقاوم للصدأ 18/8 (25 / عبوة)

The shoulder is machined dead-on straight, so my homemade hinge spins without any wobble. Took a bit of torque to drive them in, but the hex socket held up fine and the stainless finish looks clean against the aluminum.

The precision-ground shoulder on these screws made setting up a micro-adjustable hinge on my light fixture incredibly smooth. They fit perfectly and the stainless steel feels really robust for the price.

I needed a reliable pivot for a custom jig and these shoulder screws fit perfectly—the precision-ground shoulder made the alignment much smoother than using standard bolts. The stainless steel finish feels solid and corrosion-resistant, too.
