براغي ماكينة 5/16-18 × 1-1/4 بوصة | رأس مسطح مع شق مستقيم | فولاذ عادي (400/عبوة)

These are solidly made plain steel screws, the flat heads sit flush nicely when countersunk. The 5/16-18 threads cut clean and the 400 count is a good bulk value for indoor projects.

These flat heads seat perfectly flush in my counterbores, and the plain steel finish is just what I needed for the indoor jig I'm building. The 5/16-18 threads chased cleanly through my taps without any binding, and 400 pieces means I'm set for a while.

Needed a batch of 5/16-18 x 1-1/4" slotted flat heads for a jig I'm building, and these plain steel screws fit perfectly—no stripped threads so far. The 400-count package is great value for indoor projects where rust isn't a concern.
