براغي رأس سداسي مقاس 1/2-13 × 4-3/4" | فولاذ درجة 5 بطلاء زنك أصفر | خيط جزئي (25 / عبوة)

Had to torque these down pretty hard for a heavy jig assembly and the hex head held perfectly without rounding. The partial threading gave just the right grip for the thickness of the metal.

The yellow zinc finish really held up well against the grease and dirt in my shop, and the partial threads made it easy to snug them down on a heavy jig. These 4-3/4" length bolts are exactly what I needed for mounting a large motor bracket to a steel frame.

The yellow zinc coating on these cap screws looks clean and professional, which is a nice bonus for exposed machinery. Used them for a jig assembly and the hex head gripped perfectly with no rounding off. Solid fasteners for the price.
