براغي رأس كروي محزز M4 X 25 مم | فولاذ سبائكي (500 / عبوة)

I’ve used these in a few different assemblies now, and the hex socket drive makes adjustments a breeze even in tight spaces. The alloy steel feels solid and the knurled cup point holds well under vibration.

The knurled cup point on these set screws bites into the shaft really well, holding firm even under vibration. For the price of a 500-pack, the alloy steel feels solid and consistent across the batch.

The hex socket drive made seating these in a cramped bracket a breeze, even with gloves on. The knurled cup point grips the shaft firmly without chewing it up, and all 500 arrived clean and uniform.
