براغي رأس سداسية مقاس 1/4-20 × 3-3/4 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئيًا (100/عبوة)

I needed partially threaded bolts for a bracket assembly, and these cap screws fit the socket perfectly without slipping. The Grade 5 steel feels solid, and the 3-3/4" length was just right for my application.

The yellow zinc finish on these Grade 5 bolts looks solid, and the hex head makes getting a socket on them in tight spots easy. Used them to secure a vibration-prone bracket, and they've held perfectly without loosening.

Bought these for a machinery rebuild and the hex heads held up perfectly under torque without stripping. The zinc coating looks clean and should resist rust in our workshop. Worked great for the price.
