## Summary description

Proline socket extension 1/2" (21 mm) model 9033340 — a metal extension bar designed to extend reach for 1/2" drive sockets.

## Long description

Proline Socket Extension 1/2" 21 mm model 9033340 is a metal extension bar for 1/2" drive sockets, designed to increase reach and leverage for 21 mm sockets and fittings. It enables access to recessed or hard-to-reach fasteners in automotive, mechanical and maintenance work and is compatible with most locking mechanisms for square drives.
Advantages
The extension is made from chrome-molybdenum steel (CrMo) for increased durability, with approximately twice the tensile strength and three times the yield strength compared with standard tool steels. Sockets feature specially rounded profiles in the blunt corners between contact faces (PRO-DRIVE system) to reduce concentrated edge loading and minimize wear and fastener damage. Square drive fits the majority of locking mechanisms.
Suitable for
 Automotive repairs and engine work
 Mechanical assembly and disassembly
 Maintenance tasks in confined or recessed spaces
 Use with pneumatic impact tools and hand torque tools

How to use
Select a compatible 21 mm socket and attach it to the 1/2" square drive of the extension. Connect the extension to a ratchet, breaker bar, or pneumatic impact tool with a matching 1/2" drive. Use the extension to reach recessed or hard-to-access fasteners while applying torque as required. Inspect the square drive locking mechanism for proper engagement before operating pneumatic tools.
Usage recommendations
Use with appropriate torque settings and protective equipment. Avoid using damaged sockets or extensions; replace if excessive wear or deformation is observed. The extension is intended for impact and heavy-duty use—confirm compatibility of connected tools and locking mechanisms before applying high torque.
