## Long description

Long impact socket for 1/2" drive, 21 mm size, from Adler. The Adler 3513.21D long impact socket is designed for use with impact wrenches and pneumatic or electric torque tools. Its extended profile gives access to recessed or hard-to-reach fasteners while maintaining the strength and durability required for heavy-duty fastening and loosening operations in automotive and industrial environments.
Advantages
The socket is manufactured to withstand the high torque and percussive forces generated by impact tools, with material and heat-treatment processes suited to impact applications. Its long profile provides extra reach compared with standard sockets, allowing work on fasteners located in deep wells or behind obstructions. The 21 mm size fits commonly used metric fasteners and is compatible with standard 1/2" drive impact tools, offering reliable engagement and reduced risk of rounding fastener heads when used correctly.
Suitable for
 Automotive wheel and suspension repair where bolts are recessed
 Industrial maintenance and machinery servicing with deep-set fasteners
 Construction and assembly tasks requiring impact-rated sockets
 Pneumatic and electric torque tool applications
Key specifications
 Drive size: 1/2" (square drive)
 Socket size: 21 mm
 Type: Long impact socket (extended profile)
 Intended use: Impact tool compatible
 Typical materials and finish: impact-grade alloy steel with protective coating
How to use
Select the 21 mm long impact socket and attach it securely to a 1/2" drive impact wrench or breaker bar. Ensure the tool is suitable for impact sockets and set torque or power levels according to the fastener and application. Position the socket squarely on the fastener head, apply steady tool operation, and avoid side-loading the socket. After use, inspect the socket for cracking or deformation and clean any debris before storage.
Usage recommendations
Use only with impact-rated 1/2" drive tools and accessories. Do not use impact sockets on manual hand tools intended for chrome-finished sockets. Replace the socket if any signs of damage, excessive wear, or cracking appear to maintain safe operation.
