Heininger Threaded Receiver Hitch Lock for 1.25" & 2" Receivers — 1/2" Pin, Anti‑Wobble Weather‑Resistant

The Heininger Advantage threaded receiver hitch lock is a weather-resistant, anti-wobble locking pin with a 1/2" (13 TPI) threaded shaft that secures 1.25" and 2" class I–IV receiver accessories.

Keep trailers, bike racks and cargo carriers firmly attached and protected from theft with a lock built specifically for Heininger-compatible systems. The threaded 1/2" pin pairs with matching receiver pin holes and thread pitch to eliminate movement and provide reliable retention. Designed to resist the elements and simplify use, this lock ships with two keys and installs in moments without special tools.

How does this hitch lock prevent wobble on my bike rack or trailer?

The threaded design draws the hitch pin tight against the receiver, removing play that can cause rattling, misalignment or premature wear. Unlike smooth pins that rely on fit alone, the 13 threads-per-inch shaft allows you to torque the head until the accessory is snug and stable.

• 1/2" (13 TPI) threaded shaft for secure draw-in
• Works with 1.25" and 2" receivers when pin hole diameter and thread pitch match
• Suitable for Class I, II, III and IV receivers
• Provides firmer hold than non-threaded pins, reducing movement and noise

Will this fit my existing Heininger or Advantage SportsRack accessories?

Yes — the lock was made to mate with Heininger products and several Advantage SportsRack models that use a matching threaded pin. It’s compatible with Heininger SUV Twistep, Advantage glideAWAY2 and Flat Rack when those accessories have the correct hole diameter and 13 TPI thread count.

• Compatible examples: Heininger SUV Twistep (#3052)
• Also fits: Advantage SportsRack glideAWAY2 (#2110) and Flat Rack (#2035)
• Double-check pin hole diameter and thread pitch on third-party accessories
• Not compatible with smooth, non-threaded pins or different thread counts

How durable and weather-resistant is the lock head for outdoor use?

The lock head is built to resist water and road grit so it continues to turn and secure the threaded pin under outdoor conditions. Materials and finishes are chosen to limit corrosion and keep the cylinder operational through rain, salt and seasonal changes.

• Weather-resistant locking head to reduce moisture ingress
• Durable construction for long-term outdoor exposure
• Two keys included for convenient spare access
• Easy key insertion and removal designed for frequent use

How simple is installation and everyday use?

Installation is fast: slide the threaded pin through the receiver and accessory, then rotate the locking head to draw the pin tight. No special tools are required, and the included keys let you lock or unlock in seconds for routine loading and unloading.

• Quick, tool-free installation
• Threaded action tightens accessory to receiver for a secure fit
• Two keys for backup or shared use
• Designed for easy insertion and removal during regular use

Who is this for: The Heininger Advantage threaded receiver hitch lock suits vehicle owners who use tow-mounted accessories—bikes, cargo racks, steps and small trailers—and want a threaded pin that eliminates wobble and resists weather. It’s ideal if you already own Heininger or select Advantage SportsRack products with matching 1/2" (13 TPI) pin holes, or if you want a durable keyed locking pin rated for Class I through IV receivers. Before ordering, measure your accessory’s pin hole diameter and confirm the thread pitch matches 13 TPI to ensure proper fitment.
