براغي رأس مقبس #10-24 × 7-1/2 بوصة | مقبس سداسي | ملولبة جزئيًا | سبائك فولاذية بأكسيد حراري أسود (100 / عبوة)

I was a little worried the 7-1/2" length would be too long for my jig setup, but the partially threaded design lets me adjust the clamping depth perfectly. The hex socket drive made installation a breeze with my Allen wrench.

These are exactly what I needed for a jig I'm building. The 7-1/2" length and partial threading let me get a solid bite through thick steel spacers without bottoming out. Pack of 100 means I'll have spares for the next project, and they threaded cleanly without any binding.

The black oxide finish on these screws really holds up well in my jig setup, and the partially threaded design made assembly much easier than fully threaded ones I've used before. Hex drive bites perfectly with my wrench for that final torque.
