Key benefits Convert between ratchet drive sizes quickly and reliably so you can use one set of sockets across 1/4", 3/8" and 1/2" tools. Built for repeat use: tough chrome vanadium steel (50BV30) construction resists wear in workshop, garage or jobsite environments. Precise, secure connections reduce slipping and improve power transfer so sockets stay seated under torque. Simple, fast tool changes save time when switching between sockets and wrenches. Features Multi-size adapter set: 7-piece adapter and reducer set containing 4 different sizes of socket adaptors: 1/4" x 66mm, 3/8" x 64mm, 1/2" x 72mm. Allows easy switching between drive sizes for versatile applications. Material: manufactured from chrome vanadium steel 50BV30 for durability and long service life. Fit and performance: precisely machined to provide a tight, secure fit between different drive sizes to minimize slip and improve efficient power transmission. Ease of use: quick, simple design — insert the adapter into the appropriate drive and it locks securely into place for fast tool changes. Typical applications Automotive repair: switch drive sizes when working on engines, brake components or suspension where different socket drives are required. Home and workshop maintenance: use with ratchets, torque wrenches and impact adapters for appliance repair, furniture assembly or routine maintenance. Light industrial and field service: adapt sockets quickly when working on machinery or equipment that requires multiple drive sizes. What you get A 7-piece adapter and reducer set with the listed adaptor sizes: 1/4" x 66mm, 3/8" x 64mm, 1/2" x 72mm. Durable chrome vanadium (50BV30) construction, precision fit and easy, secure locking for reliable performance. Notes Use only with compatible ratchets and sockets. Follow tool and socket manufacturer guidance for safe torque limits and correct use.
