HOLO-KROME 69390 M6-1 × 8mm براغي رأس مقبس | محرك مقبس سداسي منخفض الرأس | فولاذ سبائكي بأكسيد حراري أسود (100 / عبوة)

These low-profile heads fit perfectly into tight spots on my jig build where a standard cap screw would have stuck out. The black oxide finish looks clean and seems durable so far.

Used a whole package of these on a set of jigs and they held up great through some heavy drilling. The low head profile gave me just enough clearance under the spindle guard, and the black oxide coating hasn't shown a speck of rust. For the price per hundred, you can't argue with the thread consiste

The flat head sits flush perfectly on this metal fixture, making for a much cleaner assembly than with standard cap screws. The black oxide finish held up well during repeated adjustments with my hex driver too.
