براغي ماكينة 5/16-18 × 1 بوصة | رأس ترس بمحرك مشقوق | فولاذ عادي (400 / عبوة)

The truss head on these screws is nice and wide, so they grip the metal bracket without sinking in too deep. Opened the 400-pack for a shelving project, and every single one came out of the box with clean threads and no burrs.

I needed some plain steel 5/16-18 x 1" machine screws for a quick indoor project, and this pack of 400 was exactly what I expected. The truss heads sit flush against the wood without digging in, and they work perfectly with a standard slotted driver.

I've been hunting for these exact 5/16-18 by 1-inch truss head screws for a while, and the 400-count box is perfect for my ongoing shop projects. The plain steel finish is exactly what I needed for indoor fastening, and the slotted drive gives a nice vintage feel.
