براغي رأس سداسي 1-1/8-12 × 4 بوصة | صنع في الولايات المتحدة | درجة L9 سبيكة فولاذ زنك أصفر | خيط جزئي (12 / عبوة)

Installing a heavy press in my shop, these Grade L9 bolts threaded smoothly and held the torque without a hint of deformation. The yellow zinc finish is a nice bonus for corrosion resistance.

Needed a strong fastener for a jig I was building, and the Grade L9 steel on these feels substantially tougher than the standard hardware I’ve used before. The partial threading made starting them in a threaded hole much easier.

Installed these on a heavy press and the partially threaded shank made alignment much easier than fully threaded bolts. The yellow zinc finish looks clean and the L9 alloy steel feels extremely sturdy for high-torque applications.
