براغي رأس سداسي 1"-14 × 4-1/2" | صنع في الولايات المتحدة | درجة L9 من سبائك الفولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (10/عبوة)

Used these on a heavy-duty press rebuild where the original bolts had stripped. The partial threading made alignment easier than expected, and the yellow zinc finish hasn't shown any corrosion after a week in an oily shop.

Had to torque these down pretty hard for a heavy press repair, and the Grade L9 alloy steel didn't strip or deform at all. The yellow zinc coating is a nice plus for resisting some shop grime, too.

I was second-guessing the partially threaded design, but it makes lining up the heavy equipment frame way easier. The threads are clean and catch perfectly, and the hex head grabs the socket without any slip. Solid buy for the price.
