براغي رأس سداسية 1/4-28 × 1/2 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة بالكامل (300/عبوة)

I needed a batch of these for a small fixture build, and the yellow zinc coating looks uniform and durable. The hex heads seated perfectly in my socket without any wobble, and the full threading made adjustments easy.

The threads are clean and the wrench fit is snug right out of the box, which is exactly what I need for jigs on the drill press. The full threading on these 1/4-28s makes alignment in tapped holes a breeze, and the yellow zinc has that dull, military-grade look I prefer for shop gear.

The yellow zinc coating is evenly applied and the threading is clean enough that they seat smoothly under a socket without any binding. Exactly the right grade for the equipment frame I’m bolting together, and the fully threaded length gave me solid grip through the whole joint.
