براغي ماكينة #4-40 × 5/8 بوصة | رأس مسطح بزاوية 100° مع فيليبس | فولاذ مطلي بالزنك (5000/عبوة)

Ordered a box for a panel job and the 100° flat heads really do sink in clean without leaving that annoying raised rim. The 5/8 length is just right for grabbing onto thin sheet metal, and the zinc finish hasn't shown any rust after a few humid days in the shop.

I needed a big batch for a bunch of panel assemblies, and these 4-40 x 5/8" screws have the 100° flat head that sits perfectly flush. The zinc coating looks clean and uniform across all five thousand pieces.

Finally, a small screw that doesn't strip the head the second I put pressure on it — the Phillips drive on these #4-40s bites cleanly. The zinc plating looks even and has held up well while fastening a few metal panels, and the 100° flat head sits flush without catching. Already ordered another pack
