براغي مقبس كوب 7/8-9 × 2-1/2 بوصة | فولاذ سبائكي (25 / عبوة)

These 7/8-9 set screws held up perfectly under heavy torque when I was securing a sprocket on a shaft. The cup point really digs in nicely for a solid grip.

The hex socket drive made seating these in a tight spot a breeze, and the alloy steel feels plenty tough for the torque I put on them. Threads were clean right out of the pack, no galling or debris. Exactly what I needed for a stubborn lockup.

I was a little worried about the cup point gripping properly on my shaft, but these alloy steel set screws seated firmly without any slippage. The hex socket drive took my torque wrench perfectly, and the 25-pack saved me a trip to the hardware store.
