براغي رأس سداسي 3/8-16 × 3-1/4 بوصة | صناعة أمريكية | سبائك فولاذ L9 مع طلاء زنك أصفر | خيط جزئي (400/عبوة)

The partial threads are exactly where they should be, so seating these into my equipment frame took no extra fuss. The yellow zinc finish is even and the hex heads grab a socket cleanly. These are going to last through plenty of rebuilds.

These bolts came with a clean, uniform yellow zinc finish that really resists corrosion on my outdoor equipment. The L9 alloy steel is noticeably tougher than standard hardware I've used before.

I needed high-strength bolts for a repair on a press, and these L9 grade screws torqued down perfectly without any galling. The yellow zinc finish looks good on the exposed heads, too.
