براغي رأس مقبس 1/4-28 × 5/16" | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (400 / عبوة)

I needed a solid batch of fasteners for a fixture build and these didn't disappoint. The 18/8 stainless finish is clean and uniform, and the hex socket drive grabs the Allen key without any wobble. Fully threaded the whole way, so they held tight in a precision jig with zero stripping issues.

The hex drive seated perfectly in my driver without any wobble, and the 18/8 stainless finish is clean and uniform across all 400 pieces. Threading them into my fixture plates was smooth, no binding or grit.

I've been using these screws for some custom tooling fixtures, and the 18/8 stainless steel holds up great against rust in my shop. The hex socket drive makes them easy to tighten without stripping, even in tight spaces.
