براغي رأس مقبس كاملة نقطة الكلب 1/4-20 × 1-1/2 بوصة | فولاذ سبائكي (100/عبوة)

The dog point tip seats perfectly in the shaft’s alignment hole, and the alloy steel threads cut clean without galling on the first pass. I’ve got these holding a jig together under heavy vibration, and after 20 hours of use, none have backed out a hair.

The hex drive lets me get these snug in tight corners without stripping, which is a huge plus for my metal fixtures. All 100 screws came with clean threads and consistent dog point tips, so I didn't have to sort out any duds.

Used a handful to lock down a jig setup on my drill press and the full dog point seated perfectly every time. The hex drive made adjustments in a cramped spot way easier than a regular wrench would have. 100 pieces means I won't be reordering for a long time.
