براغي ذات رأس مقبس 3/8-16 X 1-1/2" | محرك سداسي المقبس | صناعة أمريكية | خيط كامل | نحاس (100/عبوة)

Installed a set yesterday—the brass threads cut cleanly without galling, and the full threading let me adjust depth perfectly for jig assembly.

The head is perfectly machined for my hex wrenches—no stripped corners on the first few I used. Threads ran smooth into my steel fixture without any binding, and the brass finish gives them a nice, corrosion-resistant look that I didn't expect for the price.

Installed these on a jig for a drilling fixture and the threads engaged perfectly with no binding. The brass finish on these cap screws looks clean and professional, and the 1-1/2" length was exactly what I needed for this assembly.
