براغي سداسية الرأس | 5/16-18 X 2" | صناعة أمريكية | درجة L9 فولاذ سبيكة مع زنك أصفر | محززة جزئيًا (100 / عبوة)

Used these on a tractor implement rebuild — the partially threaded shank made alignment much easier than fully threaded bolts. Grade L9 held up to my torque wrench without any stretch.

Had to tighten down some heavy equipment brackets, and these hex heads let me really crank with a socket without stripping. The yellow zinc finish feels tough and should hold up fine in the shop.

The threads on these are clean and the hex heads seated perfectly with my socket wrench—no stripped corners on any of the 100. For the price, getting a full box of USA-made L9 steel with that yellow zinc is a solid deal for general shop work.
