Wera 05050220001 Socket Adapter 1/4 Inch Hex 3/8 Square

Product Description

The WERA 05050220001 is a square-drive to hex bit socket adapter designed to bridge a 3/8 inch square drive tool with a 1/4 inch hex bit. At 4 inches in overall length, it extends reach in confined fastening locations without requiring a separate extension. This adapter is built for professional use in HVAC, electrical, plumbing, and general mechanical service work where switching between drive formats is a routine part of the job. The compact form factor keeps it practical in tight engine bays, panel enclosures, or equipment access panels where space is limited.

This adapter suits technicians who carry 3/8 inch drive ratchets or impact tools and need to run standard 1/4 inch hex insert bits without swapping driver platforms. It is appropriate for residential and light commercial service calls where a single drive setup handles a wide range of fastener types. Trades that commonly use this type of adapter include HVAC installers working on equipment panels, electricians driving sheet metal screws in enclosures, and plumbers securing trim and access hardware.

Installation Notes

No installation is required for this adapter. Ensure the square drive end is fully seated and locked into the drive tool before applying torque. Inspect the adapter for cracks or wear before each use, particularly in impact applications. Discard if any deformation of the drive squares or hex shank is observed.
