Description
Overview:
The Sealey AK5400 Impact Adaptor is a heavy-duty drive converter that lets you run 1/2" (12.7 mm) drive sockets from a 3/8" (9.5 mm) drive tool. Built from drop-forged Chrome Vanadium steel for strength and durability, it features a hard-wearing phosphate finish that resists corrosion in workshop and site conditions. Designed for impact use, it is suitable for air impact wrenches and other impact tools where reliable drive conversion is needed without excessive bulk. The compact, straight-through design keeps overall length to a minimum while maintaining a secure fit between tool and socket. A practical choice for mechanics, maintenance engineers, and DIY users, this adaptor helps bridge common drive size differences across socket sets and tool kits.
Key Features:
- Converts 3/8" (9.5 mm) square drive female to 1/2" (12.7 mm) square drive male
- Drop-forged Chrome Vanadium (Cr-V) steel body for high strength and longevity
- Phosphate (black) finish for enhanced corrosion resistance and wear protection
- Impact-grade construction suited to the shock loads of pneumatic impact tools
- Compact profile reduces added length and helps access confined spaces
- Reliable fitment to minimise slop between tool and socket during heavy use
- Straightforward to use-no special setup required
- Helps standardise mixed socket sets by enabling larger 1/2" drive sockets on 3/8" drive tools
- Suitable for use in demanding workshop, garage, and site environments
- From Sealey, a recognised brand for professional hand and impact tooling
Typical Applications:
Ideal for garages, workshops, and plant maintenance where a 3/8" drive impact wrench or ratchet must operate 1/2" drive sockets. Useful for general automotive work, machinery servicing, agricultural repairs, and MRO tasks. For best results and safety, pair with impact-rated sockets on impact tools.
