Advantage Threaded Hitch Bolt & Lock — M12x1.75 for 1.25-inch Receivers, Black Anti-Rattle Replacement for Thule Snug Tite

The Heininger Advantage threaded hitch bolt & lock is a direct replacement for Thule Snug Tite hitch locks that secures 1.25" receivers with an M12x1.75 bolt and integrated KN-200-style lock head.

If your existing Thule Snug Tite or anti-rattle hitch lock is worn, lost, or you want an affordable upgrade, this Advantage replacement bolt offers the same dimensions and locking interface to restore anti-theft protection and reduce movement between your hitch and accessory. Finished in durable black, the assembly is engineered to resist corrosion, quiet hitch rattle, and simplify installation so you can get back on the road with confidence.

Will this fit my 1.25" receiver and Thule Snug Tite setup?

Yes — the bolt is sized to match Thule Snug Tite-style hardware. The M12x1.75 threaded shaft and the KN-200 compatible lock head are made to align with the same hole spacing and locking mechanism used in many factory and aftermarket anti-rattle solutions.

• M12x1.75 thread pitch for direct compatibility
• Designed for 1.25" receiver tubes and standard hitch pin holes
• Works with Thule Snug Tite-style lock heads and anti-rattle collars
• Black finish matches existing hardware aesthetics

How does it reduce noise and movement while towing?

The threaded design tightens your accessory to the receiver and the lock head holds the assembly securely in place, preventing side-to-side play. By eliminating the slack between the hitch and receiver, it cuts down on clunking and vibration that occur during acceleration, braking, and rough roads.

• Threaded torquing compresses anti-rattle collars or bushings
• Lock head prevents loosening from road vibration
• Stiff connection minimizes sway and audible rattle
• Durable finish resists wear that can increase movement over time

Is installation complicated and what tools will I need?

Installation is straightforward and can be completed with common hand tools in minutes. Remove the old pin or bolt, insert the threaded bolt through the accessory and receiver, add any anti-rattle components, then torque and lock the knob or keyed head to your preferred tightness.

• Requires basic wrench or socket set for M12 bolt tightening
• Fits the same mounting sequence as original Thule-style parts
• No vehicle modifications necessary
• Quick to remove when access or storage is needed

What materials and durability features does this replacement offer?

The Advantage replacement uses corrosion-resistant materials and a black finish that withstands weather exposure and frequent handling. The KN-200 style lock head is built to offer dependable key retention and the bolt’s threads are engineered to endure repeated installation cycles without stripping.

• Corrosion-resistant black-coated finish
• Robust lock head compatible with common keys
• Precision threads reduce galling and wear
• Constructed to last for regular towing use

Who is this for: This threaded hitch bolt and lock is for vehicle owners who use 1.25" receiver-mounted accessories—bike racks, cargo carriers, or towing adapters—and need a reliable replacement for Thule Snug Tite-style hardware.
