براغي ماكينة 1/4-20 × 2-1/2 بوصة | رأس بان مع فيليبس | فولاذ مطلي بالزنك (1000/عبوة)

Went through nearly all 1000 of these on a metal enclosure job and every single one threaded cleanly without stripping. The phillips heads seated perfectly in my driver, and the 2-1/2" length was just right for the box frames.

Bought these to anchor some steel brackets to a wood frame, and the 2-1/2" length gave me plenty of bite through both layers without any wobble. The Phillips heads seated cleanly with a standard driver bit, no stripping even when I torqued them down tight.

Exactly the right length for the metal brackets I was mounting on a steel frame, and the zinc plating kept them from rusting after a week in the damp garage. The Phillips drive seated cleanly without any cam-out issues on every single one of the hundred I used.
