براغي رأس مقبس مخروطية #4-48 × 1/4 بوصة | فولاذ سبائكي (250 / عبوة)

These little guys are surprisingly stout for their size, the cone point bites into the shaft without stripping. I picked up a pack for some tiny gearbox repairs and they held up through a lot of torque without rounding out the hex slot.

The hex socket drive made cinching these down in a tight bracket a breeze, no stripped heads or cursing. The cone point bit into the shaft exactly as it should, and 250 of them means I’m set for a long time.

The cone point seated perfectly in my shaft dimples, and the hex socket let me torque them down without stripping. Alloy steel feels solid, and all 250 arrived clean with threads intact.
