مسامير رأس سداسي مقاس 7/8-9 × 4-1/2 بوصة | صناعة أمريكية | فولاذ سبائكي PFC9 مطلي بالزنك الأصفر (10 قطع/عبوة)

I needed some high-strength fasteners for a heavy-duty press rebuild, and these 7/8-9 cap screws held up perfectly under the torque. The yellow zinc coating looks good and seems like it'll resist corrosion well, plus they're USA made which was a must for this job.

The yellow zinc finish on these bolts resists corrosion better than the plain steel ones I've used before, and the hex heads fit a standard socket perfectly. For the price, having ten USA-made fasteners this heavy-duty seems like a solid deal.

Needed these for a heavy-duty equipment repair, and the hex head on these cap screws gripped perfectly with my socket. The yellow zinc coating looks solid and the threads cut clean without any binding.
