براغي ماكينة 1/4-20 × 2-1/2 بوصة | رأس مستدير محرك مشقوق | فولاذ عادي (400 / عبوة)

Used these to fasten some heavy shelving brackets into wall studs, and the 2-1/2 inch length gave plenty of bite without going all the way through. The plain steel finish is exactly what I needed for a dry interior project. Pack of 400 should last me a good while.

The slotted heads on these are cut cleanly, so the screwdriver doesn't slip out like it does with cheaper packs. Solid 1/4-20 threading for the price, and the plain steel finish is exactly what I needed for a dry indoor project.

Needed a bunch of these 1/4-20 x 2-1/2" plain steel screws for some indoor shelving brackets, and the round head slotted drive made them easy to tighten with a regular screwdriver. The whole 400-pack came well-sorted and every thread was clean, no duds in the box. Solid value for general indoor use
