براغي ماكينة #10-32 × 1/2 بوصة | رأس ترس مع فيليبس درايف | فولاذ مع زنك ثلاثي التكافؤ (4000 / عبوة)

The trivalent zinc finish on these #10-32 screws looks clean and hasn't shown any rust after a month in my damp garage. They drive smoothly into the steel frames I'm mounting for shelving, and having a full box of 4000 means I won't run out mid-project.

I grabbed a box of these #10-32 x 1/2" machine screws for electrical panel work, and the truss head really helps distribute clamping force without marring the surface. The Phillips drive seated easily without camming out using a standard bit.

These truss heads grab nicely without slipping off the panel surface, and the trivalent zinc finish looks clean and uniform across all 4000 pieces. I’ve been using them to secure electrical enclosures and they’ve held up perfectly through assembly.
