#4-40 Machine Screws in all available lengths, grades, materials, and finishes.
To thread a #4-40 hole, drill with a #43 (0.089") tap drill for a standard 75% thread. For a clearance hole that the #4-40 screw passes through, use #31 (0.120") for a close fit or #30 (0.128") for a free fit. Pair with a matching #4-40 nut or tapped hole.
