براغي ماكينة #4-40 × 3/4 بوصة | رأس بانها مع فتحة شق | فولاذ عادي (2,700 / عبوة)

Needed a bulk pack for small jigs and fixtures, and the #4-40 size is perfect for the detail work. The pan head and slotted drive seat nicely in countersunk holes. Plain steel is fine for my indoor workshop, so this package should last me a good while.

Bought these for rebuilding an old desk lamp, and the slotted pan heads let me use a standard screwdriver without camming out. Each of the 2,700 screws is exactly 3/4 inch, so they fit perfectly into the pre-drilled holes.

Finally, an industrial-sized pack that actually holds 2,700 screws. The threads are clean and consistent, so they drive in straight without stripping. Perfect for high-volume prototype work.
