براغي ماكينة 1/4-20 × 4" | رأس مسطح فيليبس | فولاذ عادي (200 / عبوة)

I grabbed these for a heavy-duty shelving project and the 4-inch length gave me plenty of bite into the studs. The flat head sits flush against the wood without splitting it, which I really appreciate.

The threads cut cleanly into my pre-drilled holes without any binding, and the 4-inch length is perfect for securing a stack of lumber. These plain steel screws feel solid for indoor work, and the box gives you plenty to finish the job.

The flat heads sit perfectly flush, which made a huge difference on the cabinet door I was hanging. Four inches is a solid length for thicker wood, and for plain steel at this price, you're getting exactly what you pay for—a sturdy, reliable pack.
