براغي تثبيت بنقطة كوب مخددة مقاس 1/4-20 × 7/16 بوصة | فولاذ سبائكي (250 / عبوة)

The knurled cup point really bites into the shaft, no slipping even after I torqued them down hard with a hex key in a cramped spot. For 250 pieces at this price, the alloy steel feels solid and consistent across the batch. These are now my go-to for any adjustable stop or clamp setup.

Needed these for a jig I’m building, and the hex socket drive made installation a breeze in tight spots. The knurled cup point holds secure without slipping. Great value for a bulk pack of 250.

The knurled cup point really bites into the shaft, so these set screws stay put even under vibration. Tightening them with a hex key in a cramped spot was much easier than I expected—good torque without stripping.
