براغي رأس سداسية 5/8-18 × 6 بوصة | صنع في الولايات المتحدة | درجة L9 سبائك فولاذية مطلية بالزنك الأصفر | ملولبة جزئيًا (25/عبوة)

These L9 bolts show no give at all when torquing down heavy equipment mounts; the hex heads gave my socket a solid bite. The yellow zinc finish is already proving to resist a shop's worth of grime and moisture.

The threads caught perfectly on my first try, and the yellow zinc coating looks like it'll hold up well in my shop. I used these to secure a heavy motor mount, and the Grade L9 steel didn't flex at all under torque.

I needed a heavy-duty bolt for a press repair, and these Grade L9 screws handled the load without any sign of strain. The partial threading made alignment a lot easier than I expected.
