1/4-20 Socket Set Screws in all available lengths, grades, materials, and finishes.
To thread a 1/4-20 hole, drill with a #7 (0.201") tap drill for a standard 75% thread. For a clearance hole that the 1/4-20 screw passes through, use 17/64" (0.266") for a close fit or 9/32" (0.281") for a free fit. Pair with a matching 1/4-20 nut or tapped hole.
