## Long description

Proline impact socket accessory ZR18421, length 39 mm, is an adapter designed for use with impact wrenches and socket sets. Made by Proline from chromium-molybdenum (CrMo) steel, this 39 mm accessory connects and adapts sockets for heavy-duty fastening tasks in mechanic and maintenance applications where impact-rated components are required.

The CrMo construction provides enhanced tensile strength and yield point compared with standard chromium-vanadium sockets, improving durability under variable and high loads. The accessory is engineered to cooperate with pneumatic and other impact devices and features a square drive compatible with common locking mechanisms. Proline’s design reduces concentrated edge loads to protect bolt heads and prolong socket lifetime.

How to use
Fit the Proline ZR18421 adapter onto the drive of a compatible impact wrench or extension, ensuring the square drive engages the locking mechanism securely. Attach the chosen socket to the adapter and confirm a firm connection before applying torque. Use with impact-rated sockets and fasteners only, and verify that the applied torque and tool compatibility match the adapter’s intended impact use.
Usage recommendations
Inspect the adapter and mating components for wear or damage before each use, and replace if deformation or cracking is visible.
