براغي رأس سداسية 1/4-20 × 6-1/2 بوصة | صناعة أمريكية | فولاذ درجة 8 أصفر زنك (30/عبوة)

Six and a half inches of 1/4-20 threading in grade 8 steel is exactly what I needed for a stubborn machinery mount, and the yellow zinc finish looks factory-fresh out of the bag. The hex heads grabbed a socket cleanly on every one of the thirty pieces, zero stripped edges or burrs. This is the kind

The yellow zinc coating on these hex head screws is surprisingly consistent and clean across all 30 pieces, and they threaded perfectly into my steel mower deck without any binding.

I needed extra-long bolts for a custom jig I’m building, and these Grade 8 hex heads in 6-1/2” fit perfectly—the yellow zinc coating looks fresh and the threads are clean right out of the package.
