Heininger threaded receiver hitch lock for 1.25" & 2" receivers — 1/2" 13 TPI anti-wobble pin, weather-resistant head

Heininger’s Advantage threaded receiver hitch lock secures 1.25" and 2" trailer or bike-rack receivers with a weather-resistant head and an anti-wobble 1/2" (13 TPI) pin.

If you carry bikes, cargo carriers, or tow small trailers, a solid hitch lock reduces rattle and theft risk while making installations faster and cleaner. This threaded design is made to mate with Heininger products and other receivers that match a 1/2" diameter pin and 13 threads-per-inch pitch. It fits Class I–IV hitch receivers and installs quickly using the included two keys.

How does the threaded pin stop wobble and rattling?

The threaded bolt tightens into the receiver and compresses the shank, eliminating lateral movement that a straight hitch pin can't remove. That pressure stabilizes the attachment point for bike racks and cargo carriers, reducing noise and wear during travel.

• Threaded 1/2" pin (13 TPI) locks snugly into matching threaded holes
• Anti-wobble design reduces side-to-side play in the receiver
• Fits both 1.25" and 2" receivers when pin hole diameter and thread pitch match

Is this compatible with my vehicle’s hitch or my bike rack?

This lock is engineered for Heininger fittings and for any other brand that uses a 1/2" diameter pin with 13 threads per inch. It supports Class I through IV receivers, but compatibility depends on your rack’s pin-hole diameter and thread pitch, so measuring is essential.

• Works with Heininger SUV Twistep, Advantage SportsRack glideAWAY2 and Flat Rack
• Confirm pin-hole diameter and 13 TPI thread pitch before buying
• Not compatible with non-threaded or differently pitched pins

How durable is the lock in wet or salty conditions?

The locking head is weather-resistant so it withstands rain and road spray better than bare metal pins. While built to resist exterior elements, routine cleaning and occasional lubrication will extend longevity in marine or salted-road environments.

• Weather-resistant locking head helps fend off corrosion
• Included two keys for convenience and redundancy
• Periodic maintenance recommended for heavy salt or coastal use

How easy is the lock to install and use?

Installation is straightforward: thread the bolt into the receiver’s matching hole and turn until tight, then lock and remove the key. The keyed head is designed for smooth insertion and removal, so daily mounting and dismounting of racks is fast.

• Quick hand-tighten and lock operation with supplied keys
• Easy key insertion and removal for frequent use
• Compact design keeps clearance minimal behind the hitch

Who is this for: This threaded receiver hitch lock is aimed at bike owners, weekend cargo haulers, and light-trailer users who want a straightforward anti-wobble solution that also improves security. Choose this if your rack or carrier uses a 1/2" diameter pin with 13 TPI and you want a weather-resistant keyed lock compatible with Class I–IV receivers and several Heininger or Advantage SportsRack models. If you’re unsure about fit, measure your pin-hole diameter and thread pitch before purchasing to ensure a proper match.
