Socket insert bits, also known as bit sockets, combine the functionality of a screwdriver bit with the gripping power of a socket. Designed to fit ¼″ hex shank holders in drills, impact drivers, and power screwdrivers, they allow fast and efficient driving of nuts, bolts, and hex-head screws.
Available in various sizes and drive types — including hex, Torx, and square — socket insert bits are ideal for mechanical, automotive, construction, and assembly work. Many are impact-rated for use with high-torque impact drivers, ensuring durability and long service life under demanding conditions.
Manufactured from hardened steel or impact-grade alloys, these bits provide a secure fit, reduce cam-out, and make fastening quicker and more reliable.
