Enclosed External Hitch Mount – 2" Receiver for THV618 Trailer Hitch Vise

Turn your THV618 Trailer Hitch Vise into a stationary workbench vise with this heavy-duty enclosed steel hitch mount.
The Enclosed External Hitch Mount allows you to use your existing THV618 Trailer Hitch Vise on a welding table, fabrication fixture, or workbench without needing a vehicle-mounted receiver.

Featuring a fully enclosed 2" (51mm) square steel receiver welded to a flat mounting plate, the THV618-XV provides a secure mounting location for compatible hitch-style workholding accessories.

Four included 1/4"-20 knurled thumb screws help eliminate unwanted movement between the hitch mount and inserted vise shank. A separate 5/8" hitch pin locks the vise in place, just as it would in a standard vehicle receiver.

The mounting plate features multiple hole patterns for installation on Strong Hand Tools BuildPro welding tables, compatible modular fixturing tables, and conventional workbenches.

Important: This listing is for the THV618-XV Enclosed External Hitch Mount only. The THV618 Trailer Hitch Vise is sold separately.

Convert Your Trailer Hitch Vise into a Bench Vise

The Strong Hand Tools THV618 Trailer Hitch Vise is designed to fit into a standard 2" vehicle hitch receiver for portable workholding.

The THV618-XV Enclosed External Hitch Mount brings that same functionality into the workshop.

Install the mount on a compatible welding table or bench, then slide the THV618 vise into the enclosed receiver and secure it with the appropriate hitch pin.

When you need the vise for a mobile repair or field fabrication job, remove the vise from the mount and reinstall it in a compatible vehicle receiver.

This setup allows you to use one vise in multiple work locations without permanently dedicating it to a truck or workbench.

Fully Enclosed Four-Sided Receiver

The THV618-XV features a fully enclosed 2" (51mm) square receiver tube welded directly to its mounting plate.

Unlike open-bottom receiver mounts, the enclosed design supports the inserted vise shank on all four sides.

This prevents the shank from resting directly against the welding table or workbench surface beneath the mount.

The enclosed construction provides a dedicated steel receiver for securing compatible hitch-style accessories.

Four Knurled Thumb Screws for a Secure Fit

The mount includes four 1/4"-20 knurled thumb screws positioned around the receiver.

Two screws are located on top of the receiver, while the remaining two are positioned along the side.

After inserting the vise shank, tightening these screws helps take up clearance between the shank and receiver.

This reduces unwanted movement and rattling during suitable wrenching, clamping, and fabrication tasks.

Note: The thumb screws are used to stabilize the inserted accessory. The compatible hitch pin provides the primary mechanical retention and must be properly installed before use.

Compatible with BuildPro Welding Tables

The THV618-XV is designed for installation on compatible Strong Hand Tools BuildPro modular welding tables.

The mounting plate features four 0.69" (17.5mm) diameter through holes positioned on 4" (101.6mm) centers.

This hole pattern accommodates compatible fixturing tables with:

• 5/8" Holes on 2" Centers: Common Strong Hand Tools BuildPro fixturing pattern.
• 16mm Holes on 50mm Centers: Compatible metric fixturing table pattern.

The mount can be secured using appropriate table mounting bolts or compatible ball lock bolts.

Important: Welding table mounting hardware is sold separately.

Mount to Wooden or Steel Workbenches

In addition to modular welding tables, the THV618-XV can be installed on suitable conventional workbenches.

The mounting plate includes six smaller 0.35" (9mm) through holes that allow installation using appropriate lag screws or through-bolts.

This provides a practical mounting option for workshops that do not use perforated welding tables.

Always use mounting hardware appropriate for the workbench material and confirm the supporting structure is suitable for the intended workholding loads.

Designed for the THV618 Trailer Hitch Vise

The THV618-XV is specifically designed to work with the Strong Hand Tools THV618 Trailer Hitch Vise.

The THV618 vise features heavy-duty ductile iron construction, serrated pipe jaws, a built-in anvil, and a 2" receiver shank.

With the enclosed external mount, the vise can be used for many of the same workholding tasks normally performed with a fixed bench vise.

Common tasks include:

• Holding metal components during fabrication
• Securing parts for grinding or cutting preparation
• Pipe and tubing workholding
• Metalworking and assembly
• Equipment maintenance and repair
• General workshop clamping applications

Please Note: The THV618 Trailer Hitch Vise is not included with this mount and must be purchased separately.

Quick Vise Installation and Removal

The THV618-XV allows the compatible vise to be installed and removed without permanently fastening the vise itself to the table.

Basic Installation:

1. Secure the Mount: Bolt the THV618-XV to a compatible welding table, fixture, or workbench.
2. Insert the Vise: Slide the THV618 vise shank into the enclosed 2" receiver.
3. Align the Pin Holes: Position the vise until the hitch pin holes line up.
4. Install the Hitch Pin: Insert the compatible 5/8" hitch pin and secure it with the retaining clip.
5. Tighten the Thumb Screws: Adjust the four knurled screws to minimize unwanted movement between the receiver and vise shank.
6. Check the Installation: Confirm all mounting hardware and the hitch pin are secure before using the vise.

To remove the vise, loosen the thumb screws, remove the retaining clip and hitch pin, and slide the vise out of the receiver.
