براغي رأس سداسي 5/8-18 × 5 بوصة | صناعة أمريكية | فولاذ سبائكي L9 زنك أصفر | ملولبة جزئيًا (25/عبوة)

Used these to secure a heavy press at the shop and the Grade L9 alloy steel felt noticeably tougher than the standard bolts I’ve used before. The yellow zinc finish still looks clean after a week of vibration and minor exposure to oil.

These bolts threaded perfectly into my tractor's frame with no binding whatsoever. The yellow zinc coating looks quality and the hex head grabbed nicely with a socket. Exactly what I needed for a heavy repair job.

I needed heavy-duty bolts for a press rebuild and these L9s fit the bill perfectly. The hex heads hold a socket wrench securely without slipping, and the yellow zinc coating looks like it’ll resist rust well. Only wish they came in a slightly smaller quantity for smaller jobs.
