The Genius Tools GS-617M 17 Piece 3/4" Drive Socket and Accessory Set is a professional heavy-duty socket set combining 13 metric hexagon sockets from 21mm to 50mm with a selection of useful 3/4" drive accessories.

Designed for larger fasteners and demanding mechanical applications, the set includes 150mm and 200mm extension bars, a sliding T-bar and a ratchet head with handle, providing a versatile selection of tools for professional workshop, engineering and maintenance applications.

The sockets feature a 6-point / hexagon profile, providing positive engagement with correctly sized hexagonal fasteners and making them particularly suitable for applications where secure socket-to-fastener contact is required.

Accessories Included

In addition to the 13 metric sockets, the set contains:

• 150mm extension bar
• 200mm extension bar
• Sliding T-bar
• Ratchet head with handle

Together with the 13 sockets, these components make up the complete 17-piece set.

6-Point / Hexagon Socket Profile

The sockets feature a 6-point hexagon profile designed for positive engagement with conventional hexagonal nuts and bolt heads.

The six-point design closely follows the shape of the fastener and provides secure contact when the correct socket size is selected.

This makes the sockets particularly useful for larger fasteners where positive engagement and effective torque transfer are important.

3/4" Square Drive

The 3/4" square drive format is widely used for larger sockets and heavier mechanical applications.

It provides a substantial step up from smaller 1/2" drive tooling and is particularly useful for larger fasteners encountered in applications such as:

• Commercial vehicles
• Trucks and HGVs
• Agricultural machinery
• Plant equipment
• Heavy machinery
• Industrial equipment
• Mechanical engineering

The sockets and accessories within the GS-617M share the same 3/4" drive format, providing a versatile heavy-duty hand-tool system.

150mm and 200mm Extension Bars

Two extension bars are included to provide additional reach when accessing recessed or obstructed fasteners.

150mm Extension Bar

Provides additional reach while retaining a relatively compact working configuration.

200mm Extension Bar

Provides increased reach for deeper or more difficult-to-access fasteners.

Having two extension lengths available allows the user to select the most appropriate setup for the particular application.

Sliding T-Bar

The included 3/4" drive sliding T-bar provides an alternative manual driving option for the sockets.

The sliding handle arrangement allows the position of the handle to be adjusted according to the available working space and application.

This can be particularly useful when additional manual control or leverage is required.

Ratchet Head with Handle

The set also includes a 3/4" drive ratchet head with handle, providing convenient ratcheting operation for repetitive fastening and removal work.

The ratchet allows the socket to be turned repeatedly without completely removing and repositioning the drive tool after each movement.

This can help improve working efficiency during servicing, maintenance and assembly operations.

Professional Heavy-Duty Applications

The Genius Tools GS-617M is suitable for a wide range of professional applications including:

• Commercial vehicle maintenance
• Truck and HGV servicing
• Bus and coach maintenance
• Agricultural machinery
• Tractor servicing
• Plant and construction equipment
• Heavy machinery maintenance
• Mechanical engineering
• Industrial equipment
• Fleet workshops
• Engineering workshops
• Machinery servicing
• General heavy mechanical repairs

Metal Storage Case

Unlike many socket sets supplied in moulded plastic cases, the GS-617M is supplied in a dedicated metal storage case.

The case provides organised storage for the sockets and accessories, helping keep the complete 17-piece set together when stored in a workshop or transported between jobs.

The metal case also complements the professional heavy-duty nature of the 3/4" drive tool set.
