Blue Ox 1/2" Self-Retaining Tow-Bar Pins - Pair (BX88219) 1/2" Steel, Spring-Loaded Ring

These Blue Ox BX88219 1/2" self-retaining spring pins are spring-loaded tow-bar retaining pins sold as a pair that lock into place without separate clips for quick, secure hitch connections.

Designed as a direct replacement for Blue Ox tow bars, the BX88219 pins simplify trailer connections by combining spring-action retention with a stout 1/2" diameter steel shaft. Each pin provides 4" overall length with a usable shaft of about 2-3/4", offering reliable fit for common trailer and tow-bar holes while eliminating spare clips that can be lost. They’re small, rugged components that do a specific job: hold tow-bar hitch assemblies together quickly and securely.

How do these pins make hooking up my trailer faster?

The spring-loaded design lets you push the pin through aligned hitch holes and have it snap and hold in place automatically, removing the need to fumble with separate retaining clips. Removal is equally straightforward — pull the pin out by the ring when you’re ready to disconnect.

• Spring action secures pin automatically on insertion
• Integral ring provides easy one-hand removal
• Sold in a pair so you have a backup or can secure two connection points

Will these pins fit my Blue Ox tow bar or trailer coupler?

These pins are specified as direct replacement retaining pins for Blue Ox tow bars and match common 1/2" diameter hitch holes. Confirm your application requires a 1/2" pin and a usable length of roughly 2-3/4" to ensure proper engagement.

• Overall length: 4" with usable shaft around 2-3/4"

Are these pins durable and safe for towing?

• Sturdy 1/2" steel shaft resists bending in normal use

• Sold as a matched pair to replace both connection points when required
