براغي رأس سداسي مقاس 5/16-24 × 7 بوصة | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (225/عبوة)

Installed these on a heavy-duty jig I’m building, and the hex heads grabbed perfectly with a socket. The 7-inch length and Grade 8 steel feel solid—no bending under torque. Glad they’re USA made.

The packaging was solid and every single screw came out clean with sharp, uniform threads. I used a 3/8 socket on the hex head and they torqued down without stripping, exactly what I need for heavy equipment assembly. This is my second box and I'll keep grabbing these for shop stock.

I was a little worried about the thread pitch matching my project, but these 5/16-24 bolts threaded in perfectly. The Grade 8 steel and yellow zinc finish give them a solid, industrial feel, and the hex head grabs nicely with a wrench. For a pack of 225, the price feels right for the quality.
