Product information

Description

Long impact socket 3/4" (21 mm) by Adler is designed for use with impact wrenches and heavy-duty pneumatic or electric tools. The extended profile provides additional reach for recessed fasteners while the impact-rated construction resists repeated torque and shock, making it suitable for demanding workshop, automotive and industrial environments.

Advantages

The long 3/4" (21 mm) socket combines a slender profile with impact-grade material to allow access to deep-set nuts and bolts without sacrificing durability. Its design reduces the need for extensions in many applications and maintains a secure drive engagement under high torque. Built to withstand frequent use with impact tools, the socket offers reliable performance and consistent fit on matching fasteners.

Suitable for

  • Automotive repair and wheel nut removal where recessed fasteners are present
  • Industrial maintenance on machinery with hard-to-reach bolts
  • Construction and assembly tasks requiring impact-rated hand tools
  • Workshops using pneumatic or electric impact wrenches

Key specifications

  • Drive size: 3/4" (21 mm nominal socket size)
  • Profile: long/extended length for recessed fasteners
  • Tool compatibility: designed for use with impact wrenches (pneumatic or electric)
  • Construction: impact-rated material and heat treatment for high torque resistance
  • Drive connection: compatible with standard square drive impact tool adapters

How to use

Select the 3/4" (21 mm) socket for the corresponding nut or bolt head and attach it securely to the impact wrench drive. Position the socket over the fastener, ensure proper seating, and apply controlled impact torque. When removing or installing fasteners in recessed or obstructed locations, the long profile provides extra reach; avoid excessive side loading and ensure the impact tool is set to an appropriate torque setting where adjustable.

Usage recommendations

Use with compatible impact-rated extensions and universal joints if additional reach or angle is required. Regularly inspect the socket for wear, cracks or rounded corners and replace if damage is detected. Wear appropriate eye and hand protection when operating impact tools and follow the impact wrench manufacturer’s safety guidelines.
