THMMN 5th Wheel Pin Puller 31in Heavy-Duty Solid Steel

The THMMN 5th Wheel Pin Puller is a 31-inch, two-piece solid-steel hook tool that lets drivers release and move fifth-wheel trailer pins without crawling under the trailer.

Designed for truckers and anyone who regularly connects and disconnects fifth-wheel trailers, this pin puller combines a detachable two-part shaft, a comfortable 1" T-handle and chrome plating for corrosion resistance. The tool provides mechanical advantage to push or pull the locking dowel with reduced bending, grease contact, and strain. Compact when separated, it stows easily in cab toolboxes and is rated for heavy-duty use thanks to high tensile-strength components.

How does this pin puller reduce effort and mess?

The THMMN hook transfers force through a long shaft, letting you operate pins from beside the trailer rather than underneath it. That keeps you away from grease, cramped spaces and awkward postures, making hitching and unhitching faster and cleaner.

• 31" total length gives reach without crawling under trailers
• Two-piece, threaded connection for compact storage and firm assembly
• Hollow T-handle reduces weight and reduces hand fatigue
• Chrome plating decreases rust and makes cleanup easier

What are the build and strength specifications?

This model is constructed from solid steel with a chrome finish and designed for repeated heavy use. Critical screw and solid parts show high tensile strength values suitable for demanding towing environments.

• Total length: 31" (two 15.5" sections)
• Rod diameter: 0.4"; handle diameter: 1"; handle length: 5"
• Screw parts tensile strength: 14.69 kN (≈1.5 tons direction force)
• Solid parts tensile strength: 589 Rm/MPa for robust durability

How do you use and care for the tool safely?

Assemble the two threaded sections until secure, then apply force along the shaft axis to pull or push the pin. Avoid levering, bending, or side-prying motions that could damage the tool or the trailer components.

• Connect threaded joint tightly before each use
• Apply straight-line push or pull force only
• Store disassembled in a toolbox or cab to protect threads and finish
• Wipe chrome surface to remove road grime and extend service life

What other tasks can this hook handle?

Beyond fifth-wheel pin removal, the hook’s geometry and strength make it useful for moving heavy garage doors, carts, crates and similar items that require reach and leverage. Its compact two-piece design also makes the tool practical for general-purpose roadside adjustments.

• Pulling cotter-style pins and locking dowels
• Shifting rollers, carts or light machinery parts
• Temporary lever for aligning hitch components during hookup
• Easy storage in cab compartments or roadside kits

Who is this for? The THMMN 5th Wheel Pin Puller is intended for professional drivers, owner-operators and fleet mechanics who want a durable, portable solution to release fifth-wheel pins without crawling under trailers. It’s also a useful multi-purpose tool for homeowners and workshop users who need reach and leverage for heavy items, provided they follow the usage guidance to avoid side-loading the shaft.
