براغي رأس سداسية مقاس 5/8-11 × 11 بوصة | صناعة أمريكية | درجة L9 سبائك فولاذية زنك أصفر | خيط جزئي (25 / عبوة)

Put these on a large press rebuild and the L9 alloy is noticeably harder than standard grade 8—no issues with stripping or stretching so far. The partial threads made alignment easier since I could get them started before the threads engaged.

I needed heavy-duty bolts for a press rebuild and these L9s are a perfect fit. The 5/8-11 threading was clean and the yellow zinc coating looks solid right out of the package.

Used these to secure a piece of equipment to a steel frame, and the yellow zinc coating held up fine against my wrench without stripping. The partial threading made alignment easier than fully threaded bolts I've dealt with before. Solid buy for the price.
