HOLO-KROME 69328 براغي رأس مقبس M4-0.7 × 20 مم | محرك سداسي برأس منخفض | فولاذ سبائكي بأكسيد حراري أسود (100/عبوة)

I was pleasantly surprised by the hex socket drive engagement on these M4 screws—much more secure than the Phillips heads I’ve used before, and the low profile is perfect for tight jig assemblies.

The black oxide finish on these M4 screws looks even better in person, and the low head profile made them perfect for a jig I was building where clearance was tight. All 100 pieces arrived clean and threaded smoothly into their holes without any binding.

I needed low-head screws for a tight clearance on a jig, and these 20mm M4s fit perfectly without protruding. The hex socket drive gripped well without any stripping during install.
