براغي ذات رأس سداسي 1/2-20 × 2-3/4 بوصة | فولاذ درجة 5 مع زنك أصفر | ملولبة جزئيًا (50 / عبوة)

Used these to mount a heavy-duty bracket in my shop; the partial thread made it easy to snug everything down without cross-threading. The yellow zinc finish looks good and should hold up fine against corrosion.

The hex heads seated perfectly with a socket, and the yellow zinc finish looks consistent across all fifty pieces. Threads were clean with no burrs, so they drove in smoothly for my equipment build. Exactly what I needed for the job.

I needed some strong partially threaded bolts for a heavy equipment frame repair, and these Grade 5 hex heads fit my 1/2-20 tap perfectly. The yellow zinc coating looks uniformly applied and shows no flaking after tightening with a socket.
