DEDRA 17H309 impact socket accessory

The Universal Joint Socket Adapter Dedra 1/2" CrV model 17H309 is a 1/2-inch drive accessory designed to add angular flexibility between a ratchet or extension and a socket. Manufactured from chrome vanadium (CrV) steel, the adapter enables access to fasteners located at tight or offset angles while maintaining a secure connection to standard 1/2" sockets and drive tools. It is intended for workshop and automotive use where direct access is restricted by obstructions or limited clearance.

Advantages

The chrome vanadium construction provides strength and wear resistance for repeated use under load. The universal joint mechanism delivers a smooth pivot action that preserves torque transfer while allowing significant articulation. The 1/2" drive format ensures compatibility with a wide range of ratchets, extension bars and socket sets commonly used in automotive repair, machinery maintenance and general workshop tasks.

Suitable for

• Reaching fasteners located behind obstacles or within confined engine compartments
• Maintenance and repair of vehicles, agricultural machinery and industrial equipment
• Workshop assembly and disassembly tasks where angled access is required

Key specifications

• Drive size: 1/2" compatible with standard 1/2" sockets and tools
• Material: chrome vanadium (CrV) steel for enhanced durability
• Function: universal joint providing angular articulation between tool and socket
• Connection type: square drive with retaining detent or friction fit as used on standard 1/2" accessories

How to use

Attach the universal joint adapter to the square drive of a 1/2" ratchet, extension or handle by pushing it onto the drive until it seats securely. Connect the appropriate 1/2" socket to the adapter. Position the tool assembly so the universal joint aligns with the required angle to reach the fastener. Apply steady, controlled torque while keeping alignment as consistent as possible; avoid sudden impacts or excessive bending beyond the joint's intended angle. After use, remove and inspect the adapter for wear before storage.

Usage recommendations

Use the adapter within the rated capacity of your sockets and drive tools. Avoid using universal joint adapters as a substitute for properly sized extensions when high torque or precision is required. Regularly inspect the joint and contact surfaces for wear or deformation and replace the adapter if any damage is found.
