5/8-18 X 7/8" براغي ضبط ذات رأس كوبي مخدد | سبيكة فولاذ (50/عبوة)

The knurled cup point on these set screws gave me a much better bite into the shaft than standard points, and the hex drive made tightening them in a tight spot a breeze. All fifty arrived clean and well-threaded for the price.

I needed a high-torque adjustment for a tight motor mount, and these set screws gripped perfectly with that hex socket drive. The knurling on the cup point made installation feel secure without slipping. Great value for a pack of 50.

The knurled cup point bit into the shaft cleanly and held fast even with some serious vibration. For a fifty-pack at this price, the alloy steel feels solid and the hex socket drive made adjustment in a cramped spot way easier than I expected.
