3/8-16 × 2-3/4" براغي رأس سداسي | صناعة أمريكية | سبيكة فولاذ درجة L9 زنك أصفر | خيط جزئي (450 / عبوة)

The yellow zinc coating on these grade L9 bolts looks uniform and clean, and they threaded into my equipment frame without any binding. Used a full box on a hydraulic press rebuild and every one seated perfectly.

Needed a batch of cap screws for a custom assembly line build, and these fit the bill perfectly. The partially threaded shaft gives just the right grip depth for our steel brackets, and the hex head held up well under torque without any rounding.

Installed these on a press brake at work and the partially threaded shank made alignment much easier than fully threaded bolts. The yellow zinc finish looks good and the hex head seated perfectly with a standard wrench.
