براغي رأس سداسي 7/16-14 × 3 بوصة | صنع في الولايات المتحدة | درجة L9 سبائك فولاذية صفراء زنك | خيط جزئي (50 / عبوة)

Finally, a hex cap screw that doesn't strip when torqued to spec—the L9 alloy steel feels noticeably tougher than the ones I've been using. Thread engagement was smooth too, no binding halfway in on my equipment mount.
