Apex EX-372-B Socket Drive Adapter 3/8 to 1/4 Inch

Product Description

The APEX EX-372-B is a socket drive adapter that converts a 3/8 inch square male drive to a 1/4 inch square female drive. With an overall length of 1 inch, this compact adapter lets technicians switch between drive sizes without changing ratchets or impact tools. It meets ANSI standards and carries a 1-year warranty. HVAC techs, plumbers, electricians, and general trade professionals use this type of adapter daily when working in confined equipment spaces where drive size flexibility is essential.

This adapter is suited for residential and light commercial service work across trades. It fits into standard tool kits used for panel access, equipment mounting hardware, and general fastener work. The 3/8 inch to 1/4 inch reduction is one of the most common drive conversions needed when a technician has a larger ratchet on hand but needs to run smaller socket sizes for tight or precision fastening applications.

Installation Notes

This adapter is a hand tool accessory installed by any trade professional using socket-based fastening equipment. No power-down or system shutoff is required for the adapter itself, but always de-energize or isolate any equipment being serviced before using drive tools on electrical panels, HVAC components, or pressurized systems. Inspect the adapter for wear or damage before use and do not exceed the torque rating of the smaller 1/4 inch female drive end.
