The Genius Tools TG-312M 12 Piece 3/8" Drive Metric Swivel Impact Socket Set is designed for professional applications where impact strength, manoeuvrability and restricted-access capability are essential.

Combining an impact-rated socket design with an integrated flexible swivel joint, these sockets allow improved access to nuts and bolts positioned at difficult angles or behind surrounding components where a conventional straight impact socket may be difficult to use.

The 3/8" square drive format makes the set particularly well suited to automotive servicing, mechanical engineering, machinery maintenance and other professional workshop applications where compact impact tooling is required.

The set provides a complete consecutive metric size range from 8mm through to 19mm, giving technicians 12 commonly used sizes without gaps.

Each socket is engineered to withstand the high torque and repeated loading associated with compatible impact tools, while the swivel design provides additional freedom of movement when working in confined areas.

For applications requiring additional reach, a matching TG-312MD Deep Swivel Impact Socket Set is also available separately.

This provides 12 consecutive metric sizes from 8mm through to 19mm, covering a useful selection of commonly encountered automotive and mechanical fasteners.

Flexible Swivel Impact Design

Unlike a conventional straight impact socket, each TG-312M socket incorporates a flexible swivel joint between the square drive and socket body.

This allows the socket to operate at an angle relative to the impact wrench, providing additional manoeuvrability when direct straight-line access to the fastener is restricted.

The swivel configuration can be particularly useful when working around:

  • Engine components
  • Engine bays
  • Gearboxes and transmissions
  • Suspension assemblies
  • Brake components
  • Chassis assemblies
  • Machinery
  • Agricultural equipment
  • Plant equipment
  • Industrial installations

The design allows technicians to approach fasteners from alternative angles where surrounding components prevent direct access.

Designed for Impact Tools

The TG-312M sockets are specifically designed for impact applications.

They are suitable for use with compatible equipment including:

  • Pneumatic air impact wrenches
  • Cordless impact wrenches
  • Other compatible 3/8" drive impact equipment

Impact sockets are engineered to withstand the repeated loading generated by powered impact tools, making this set suitable for demanding professional workshop applications.

Always ensure the impact wrench, socket and application are appropriately matched before use.

3/8" Square Drive

The complete set uses a 3/8" square drive, providing a useful balance between compact dimensions and professional fastening capability.

The 3/8" format is particularly well suited to automotive and mechanical applications where access is restricted and the bulk of a larger drive system may be undesirable.

Combined with the swivel mechanism, the compact 3/8" drive format makes the TG-312M especially useful for difficult-access fastening work.

Improved Access in Confined Areas

The principal advantage of the TG-312M set is the ability to combine powered impact operation with angled socket access.

When a conventional impact socket cannot be aligned directly with the fastener, the integrated swivel joint provides additional flexibility.

This can help reduce the need for separate universal joints and socket combinations in suitable applications, providing a compact integrated solution for restricted-access work.

Standard Profile Swivel Sockets

The TG-312M is the standard-profile version of the Genius Tools 3/8" drive swivel impact socket range.

Its compact socket profile is particularly useful where available space around the fastener is limited.

For applications involving recessed nuts, longer studs or fasteners positioned deeper within an assembly, the corresponding Genius Tools TG-312MD Deep Swivel Impact Socket Set is available separately.

Deep TG-312MD Version Also Available

For technicians requiring additional socket depth, Genius Tools also offers the TG-312MD 12 Piece 3/8" Drive Deep Swivel Impact Socket Set.

The matching deep-profile set also covers:

8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19mm

The two sets provide a choice between:

  • TG-312M – Standard-profile swivel impact sockets
  • TG-312MD – Deep-profile swivel impact sockets

This allows technicians to select the socket depth best suited to the particular fastener and working environment.

Frequently Asked Questions

What is a swivel or flexi impact socket?
A swivel impact socket incorporates an integrated flexible joint between the square drive and socket body, allowing the socket to operate at an angle to the impact wrench. This provides improved access to fasteners positioned behind or around surrounding components where a conventional straight impact socket may be difficult to align.
What sizes are included in the Genius Tools TG-312M Swivel Impact Socket Set?
The TG-312M contains 12 consecutive metric sizes from 8mm to 19mm: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19mm. This provides a useful range of commonly encountered sizes for professional automotive, mechanical and engineering applications.
Why choose 3/8" drive swivel impact sockets for restricted-access work?
The 3/8" square drive provides a compact format that is particularly useful where working space is limited. Combined with the integrated swivel mechanism, these sockets are well suited to difficult-access areas around engines, transmissions, brakes, suspension assemblies and machinery.
Can the TG-312M sockets be used with pneumatic and cordless impact wrenches?
Yes. The TG-312M sockets are specifically designed for impact applications and are suitable for compatible 3/8" drive pneumatic air impact wrenches and cordless impact wrenches. Always ensure the socket, impact tool and fastener are appropriately matched for the application.
What is the advantage of an integrated swivel socket compared with using a separate universal joint?
The integrated swivel design combines the impact socket and flexible joint into a single compact assembly, providing additional manoeuvrability without requiring a separate universal joint and socket combination in suitable applications. This can be particularly useful where both overall tool length and access around the fastener are restricted.
Can swivel impact sockets be used at any angle under full impact load?
Swivel sockets are primarily designed to improve access and working angle, and the straightest practical alignment should be used whenever possible for efficient torque transfer. Always ensure the socket is fully engaged with the fastener before operating the impact wrench and avoid unnecessarily severe operating angles.
