براغي رأس سداسية 1/2-13 × 4 بوصة | صناعة أمريكية | درجة L9 سبيكة فولاذية مطلية بالزنك الأصفر | ملولبة جزئيًا (25/عبوة)

Used these to bolt down a heavy duty workbench and they torqued down smooth without stripping. The partial threading gave just the right grip for a 4" bolt, and the yellow zinc coating looks clean out of the box. Exactly what I needed for the job.

The yellow zinc finish held up well during installation without scratching off like cheaper coatings I've used. Threads were clean and the partial threading made alignment easier on the equipment I was working on. Only gripe is the lack of extra thread length for applications needing more engagement

The partially threaded design is handy for certain applications, but I wish the threads were a bit cleaner—a couple bolts had slight burrs. Still, for the price and USA-made quality, they get the job done fine on medium-duty projects.
