براغي رأس سداسي 1/4-20 × 3/4" | صناعة أمريكية | سبائك فولاذ درجة L9 زنك أصفر | ملولبة بالكامل (100 / عبوة)

Used these for mounting a small motor bracket on my lathe — the yellow zinc coating is a nice touch, holds up well against oil splashes. Each screw threaded smooth and snug with no binding. Exactly what I needed for a solid mechanical hold.

I needed replacements for a jig fixture at work, and these L9 alloy screws held torque perfectly during assembly without any stripping. The yellow zinc coating looks good and should resist rust in our shop environment.

Installed these on a mower deck rebuild and every single one threaded in smoothly without any galling. The yellow zinc finish looks consistent across all 100 pieces, and the hex heads hold a socket perfectly.
