Trailer Hitch Vise – 2" Receiver, 7,700 lb. Clamping Force

Heavy-duty portable vise that turns a standard 2" trailer hitch receiver into a workholding station.
The Trailer Hitch Vise provides a convenient way to clamp, hold, and work on metal parts wherever a compatible 2" receiver is available. Designed for mobile welding, fabrication, repairs, and field maintenance, this vise mounts directly into a truck, trailer, tractor, or shop-mounted hitch receiver.

Built from 60,000 PSI ductile iron, the THV618 delivers up to 7,700 lbs. of clamping force with a maximum jaw opening of 5.7" (146mm). The vise features wide flat jaws, serrated pipe jaws, a built-in anvil, and removable locating pins for different workholding applications.

Its portable design provides a practical alternative to a permanently mounted bench vise. Simply slide the shank into a standard 2" (51mm) receiver and secure it using the included hitch pin and R-clip.

When you need a stationary workshop setup, the THV618 can also be mounted directly to compatible Strong Hand Tools BuildPro welding tables using the mounting holes in its base flange.

Turn Your Trailer Hitch Into a Portable Workbench

A traditional bench vise is useful in the shop, but it is not always available where the work needs to be done.

The THV618 Trailer Hitch Vise provides a portable solution by mounting directly into a standard 2" square hitch receiver.

Once installed and secured with the included hitch pin, the vise extends outward from the receiver to provide access to the jaws and workpiece.

This setup is useful for field repairs, mobile fabrication, equipment maintenance, and other tasks where a stationary workbench may not be available.

When the job is finished, remove the R-clip and hitch pin, then slide the vise out of the receiver for storage.

Heavy-Duty 7,700 lb. Clamping Force

The THV618 is manufactured from 60,000 PSI ductile iron, providing a durable workholding body designed for demanding applications.

With up to 7,700 lbs. of clamping force, the vise helps secure workpieces during cutting, grinding, welding preparation, wrenching, and general repair operations.

Its ductile iron construction is designed to provide better resistance to shock and impact than conventional gray cast iron.

The THV618 is suitable for workholding applications where a secure grip and durable construction are important.

Wide Flat Jaws for Secure Workholding

The THV618 features 5.9" (150mm) wide jaws with a maximum opening of 5.7" (146mm).

The wide jaw faces provide a substantial gripping surface for holding flat stock, metal components, and fabricated workpieces.

This design makes the vise useful for many common metalworking tasks, including cutting, grinding, assembly, and maintenance.

Integrated Serrated Pipe Jaws

In addition to the standard flat jaws, the THV618 includes serrated V-groove pipe jaws positioned below the flat jaw faces.

These jaws are designed to grip round materials such as pipe, tubing, and round bar.

The serrated surfaces help reduce unwanted rotation of the workpiece while it is being held, making the vise useful for pipe-related fabrication and repair work.

Built-In Anvil for Metalworking

The top of the fixed jaw incorporates a 5.9" x 2.4" (150 x 62mm) anvil surface.

This flat working area provides a convenient surface for suitable metalworking operations such as straightening, flattening, and peening.

Because the anvil is cast directly into the vise body, it provides a dedicated working surface without requiring a separate anvil.

Four Locating Pins for Repeatable Positioning

The THV618 includes four removable 5/16" (8mm) locating pins that can be positioned in the holes on top of the jaws.

Each jaw features four locating holes, allowing the pins to be arranged as stops or fences for different workholding applications.

These pins are useful when positioning repeated workpieces or holding certain shapes that may be difficult to locate against the flat jaws alone.

They provide additional flexibility when using the vise for fabrication, assembly, and maintenance.

Dual Mounting Options – Hitch Receiver or Welding Table

The Strong Hand Tools THV618 provides two mounting options for different work environments.

Option 1: Standard 2" Hitch Receiver

Slide the vise into a compatible 2" receiver and secure it using the included 5/8" hitch pin and R-clip. This mounting method is useful for mobile workstations and field repairs.

Option 2: BuildPro or Compatible Fixturing Table

The base flange allows the vise to be bolted directly to compatible modular welding tables with:

• 5/8" holes on 2" centers
• 16mm holes on 50mm centers

This allows the THV618 to serve as a stationary vise on a compatible fabrication table.

Mounting Note: The hitch pin and R-clip are included. Table-mounting hardware is not specified as included and should be selected separately for the work surface.

Quick Installation and Removal

The THV618 is designed for fast installation without permanent modifications to a compatible receiver.

1. Prepare the Receiver: Ensure the receiver is properly installed, secure, and suitable for supporting the vise.
2. Insert the Vise: Slide the vise shank into the standard 2" square receiver.
3. Align the Mounting Holes: Position the vise so the hitch pin can pass through the receiver and shank.
4. Install the Pin: Insert the included 5/8" hitch pin and secure it with the R-clip.
5. Secure the Workpiece: Position the material between the appropriate jaws and tighten the vise.

When finished, release the workpiece, remove the R-clip and hitch pin, and slide the vise out of the receiver.
