براغي رأس كوبية مقاس #6-32 × 7/16 بوصة | فولاذ سبائكي مطلي بالزنك (1000/عبوة)

These little set screws fit perfectly in my CNC machine's adjustment collars, and the cup point really bites into the shaft without slipping. The zinc plating looks clean and should resist rust fine in my shop.

The hex socket drive made cinching these into tight spots under the machine frame a breeze, and the cup point bites down firmly without stripping. I used about half the bag on one job and not a single one failed me.

These are exactly what I needed for a tight motor mount adjustment. The hex socket drive lets me apply good torque without stripping, and the zinc plating gives them a clean finish. A solid batch with no bad threads in the whole bag.
