Apex QR-508 Socket Adapter 1/2 Drive to 1/4 Hex Bit

Product Description

The APEX QR-508 is a socket adapter that converts a 1/2 inch square drive to a 1/4 inch hex bit shank. It allows technicians to run hex-shank driver bits directly from a 1/2 inch drive ratchet, impact wrench, or torque wrench without changing tools. The adapter measures 2.125 inches overall length with a 0.875 inch body diameter. It is a compact, direct-connect solution used in mechanical, electrical, HVAC, and plumbing service work wherever a hex bit needs to be driven with 1/2 inch drive torque output.

This adapter fits standard trade service applications where a technician needs to switch between square-drive sockets and hex-shank bits on a single 1/2 inch drive tool. Common install scenarios include equipment assembly, panel work, and mechanical fastening tasks in residential and light commercial environments. The QR-508 is appropriate for any trade that works with both socket sets and hex bit accessories on the same job.

Compatibility

Designed for use with any standard 1/2 inch square-drive ratchet, breaker bar, or impact wrench and any standard 1/4 inch hex-shank driver bit.

Installation Notes

Insert the 1/2 inch square-drive male end into the drive tool and seat the 1/4 inch hex bit fully into the female receiver before applying torque. Verify the bit is fully engaged before use to prevent cam-out or adapter ejection under load. When using with an impact wrench, confirm the adapter and bit are rated for impact-rated service before applying high-cycle percussion torque.
