براغي رأس سداسية 1/4-28 × 3/4 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة بالكامل (300/عبوة)

The hex head grips a socket perfectly, no rounding even when I torqued them down hard. The yellow zinc coating looks uniform across all 300 pieces, and the threading was clean right out of the bag. Exactly what I needed for reassembling my shop press.

I used these to rebuild a small engine mount and the Grade 5 rating held up perfectly under torque. The yellow zinc coating looks clean and hasn't shown any rust after a week in a damp garage.

Finally got around to using these on a small fixture I was building, and being grade 5 steel with a yellow zinc finish, they're tougher than the cheap zinc-plated ones I used before. The hex head fit my socket perfectly without any stripping, and having 300 in the pack means I won't have to reorder
