1/4-20 X 3" براغي رأس كبس | رأس مسطح سداسي | كامل الخيط | فولاذ سبائكي مؤكسد أسود حراري (100 / عبوة)

These bolts fit perfectly into my jig frame, and the black oxide finish held up well against the metal shavings. The hex drive made installation smooth with no stripping at all.

Needed some longer fasteners for a custom jig I was building, and these 3-inch screws with the hex socket drive made installation much easier in tight spots. The black oxide finish adds a nice bit of corrosion resistance too.

Bought these for a fixture table and they thread in smooth as butter—no binding or cross-threading even with the 3-inch length. The hex socket grabs well with a ball-end driver, and the black oxide finish wipes clean without rusting. Solid value for a hundred pieces.
