Description
Overview:
The Draper Tools Male to Female Converter 1/4M to 3/8F (model 31999) is a compact, workshop-grade adapter for everyday hand tools. Built from durable steel with a corrosion-resistant finish, it converts a 1/4 inch (6.35 mm) male square drive to a 3/8 inch (9.53 mm) female square drive. This lets you use 3/8 inch sockets on 1/4 inch drive tools without changing your ratchet or handle. It suits standard hand-operated socket sets and accessories used in garages, workshops, and on-site maintenance. Whether you are a tradesperson or a DIY user, this adapter provides a simple way to bridge drive-size gaps across ratchets, extensions and torque wrenches, helping you get more from the tools you already own. Draper's build quality ensures reliable performance and long service life.
