براغي سداسية 5/16-18 × 1 بوصة | فولاذ مع طلاء زنك أصفر (200/عبوة)

Used a full bag mounting a shelving unit, and every single one threaded cleanly without any binding. The hex heads gave my socket wrench a solid grip even in tight corners.

The yellow zinc finish on these is more consistent than cheaper packs I've used, and the hex heads hold up fine under moderate torque from my impact driver. Exactly what I needed for mounting brackets in a pinch.

I needed a solid batch of fasteners for some machine frame repairs, and these 5/16-18 hex cap screws fit the bill perfectly—the cadmium yellow finish resists rust nicely. Each one engaged smoothly with my wrench, and the 200-count package gives me plenty of spares for future projects.
