براغي ذات رأس سداسي 9/16-12 × 2 بوصة | صنع في الولايات المتحدة | PFC9 فولاد سبيكي مطلي بالزنك الأصفر (25/عبوة)

I'm a machinist and needed a reliable batch for a high-torque equipment repair; these hex heads fit my 9/16 socket perfectly. The alloy steel feels solid with no burs or defects right out of the package.

The yellow zinc coating is consistent all the way down the threads, no bare spots or flaking. I've used these on a couple of fab projects and the hex heads have held up to repeated wrenching without rounding out. Solid buy for the price.

Torqued these down on a milling machine bracket and the yellow zinc coating held up nicely against oil and chips. The hex head gave my socket a solid grip without slipping. For the price, you're getting real US steel that feels stronger than the imports I've used before.
