براغي ماكينة 1/4-20 × 3 بوصات | رأس كمثرى بمحرك مشقوق | فولاذ مطلي بالزنك (600/عبوة)

I needed exactly 600 screws for a large metal frame project, and the truss head sits flush against the panels without binding. The zinc finish handled a bit of rain during assembly without any rust.

These 1/4-20 screws worked perfectly for mounting a metal control panel to an enclosure frame. The truss head sits flush without protruding, and the slotted drive gives good torque with a standard screwdriver. I was impressed that all 600 screws in the package had consistent threads and no burrs.

The zinc coating on these screws is holding up well against rust in my garage setup, and the truss head distributes pressure evenly on the steel brackets I’m fastening. Threads cut cleanly with no binding, even at this length. Solid value for the price.
