براغي رأس سداسية 1/4-20 × 5-1/2 بوصة | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (50/عبوة)

The partial threading on these cap screws made aligning them into my equipment frame so much easier than fully threaded bolts. The yellow zinc finish looks clean and seems like it'll resist rust well in my shop.

Got these for a stubborn machinery frame that needed longer fasteners than the hardware store carried. The 1/4-20 threads grabbed cleanly with a standard socket, and the partial threading made alignment a lot easier than fighting a fully threaded bolt. Solid grip, no stripping on the first pass.

The yellow zinc coating on these bolts is really consistent across all 50, and the partial threading makes them perfect for when you need to adjust the clamping depth on a press fixture.
