براغي رأس سداسية مقاس 3/8-16 × 2-1/4 بوصة | فولاذ درجة 2 مطلي بالزنك الأصفر | ملولبة جزئيًا (550 / عبوة)

I was tired of buying fully threaded bolts that wouldn't seat flush in my equipment, and these hex heads with the partial thread solved that perfectly. The yellow zinc coating looks clean and the 550 count is more than enough for multiple projects.

The partial threading makes them sit perfectly flush when I'm bolting down steel brackets, and the yellow zinc finish hasn't shown a speck of rust after a month in a damp shop. At 550 per box, I'll be set for years of machine repairs.

Bought these for a jig I was building and the yellow zinc finish is holding up nicely, no rust after a few humid days. The 3/8-16 threads caught cleanly on the first try with my socket, and the partial threading gave me the grip I needed without extra hardware.
