براغي رأس سداسي 1/2-20 × 1-1/2" | صناعة أمريكية | سبيكة فولاذ درجة L9 أصفر زنك | ملولبة بالكامل (50 / عبوة)

I needed fully threaded bolts for a heavy machinery repair, and these Grade L9 hex heads torqued down perfectly without any stripping. The 50-count package gave me spares for future projects too.

The yellow zinc finish is a nice touch — they look clean and don't show handling marks after a full day of wrenching on the assembly line. Threads cut perfectly into the tapped holes with zero binding, and the L9 alloy feels plenty stout for heavy equipment frames.

Used these to secure a heavy bracket on a press table – the yellow zinc finish held up perfectly against oil and grime. Threads were sharp and clean, let me run them in by hand before torquing. Exactly what you want from L9 bolts.
