## Summary description

Makita adapter B-68460 converts a 1/2" drive to a 7/16" drive for use with impact wrenches. Made of CR-MO (chromium-molybdenum) steel for enhanced durability under impact loads. Designed to allow use of 7/16" sockets on 1/2" impact tools, suitable for automotive, construction, and maintenance tasks requiring high torque transfer.

## Long description

Makita adapter B-68460 converts a 1/2" drive to a 7/16" drive, enabling the use of 7/16" sockets on 1/2" impact wrenches. Manufactured from chromium-molybdenum (CR-MO) steel, the adapter is designed to withstand repeated impact loads and transmit high torque from the tool to the socket. It is intended as a simple mechanical interface that expands socket compatibility for professionals and hobbyists working in automotive repair, construction, or general maintenance.
Advantages
The adapter is made of CR-MO steel to provide enhanced strength and resistance to shock during use with impact wrenches. Its compact design minimises added length while maintaining secure fitment between a 1/2" square drive and a 7/16" socket. The conversion allows efficient transfer of torque with reduced risk of deformation compared with softer materials, supporting repeated heavy-duty use.
Suitable for
Automotive repair tasks that require 7/16" sockets on 1/2" impact wrenches
Construction and installation work using power impact tools
Maintenance and service operations where occasional socket size conversion is needed
Workshops and professional tool kits aiming for greater socket compatibility
When it may not be suitable
The adapter is intended for use with impact-rated sockets and impact tools; using it with non-impact sockets or hand tools may lead to improper fit or accelerated wear. It is a mechanical converter and does not provide torque multiplication or reduction—users should ensure the socket and fastener ratings are suitable for the torque produced by the impact wrench.
Key specifications
Drive conversion: from 1/2" square drive to 7/16" square drive
Material: chromium-molybdenum (CR-MO) steel
Designed for use with impact wrenches
Compact, single-piece adapter construction
How to use
Attach the adapter onto the 1/2" square drive of the impact wrench until it locks or seats securely according to the tool's detent or retaining mechanism. Fit the required 7/16" impact socket onto the adapter, ensuring a firm connection before applying torque. Operate the impact wrench at appropriate speed and torque settings for the fastener and socket rating. After use, remove the socket and adapter, inspect for wear or damage, and store in a dry place.
What to consider before purchase
Compatibility with your impact wrench drive size (1/2" required)
Use only with impact-rated 7/16" sockets to avoid damage
Ensure the adapter material and construction meet your durability needs
Check whether added adapter length affects access in tight spaces
Usage recommendations
Use the adapter exclusively with impact-rated sockets and regularly inspect for signs of cracking, rounding, or wear. Avoid using the adapter to extend leverage or as a substitute for properly sized tools. For consistent performance, pair the adapter with tools and sockets designed for similar torque ranges.
