براغي مقبس نقطة الكوب M6 × 45 مم | سبيكة فولاذ (100 / عبوة)

These set screws held firm on a jig I built, the cup point really digs in and prevents slipping. The hex socket made it easy to tighten them down in a cramped spot with just an Allen key. A solid pack for the price, all 100 threads were clean and consistent.

The cup point really bites into the shaft, so even after a few days of vibration nothing has loosened up. All 100 screws in the pack were cleanly threaded and the hex socket fit my driver perfectly.

These set screws have a solid, precise feel when you seat the hex key—no wobble at all. The cup point really grips the shaft, so I’m confident they won’t back out under vibration.
