Blue Ox 1/2" Self-Retaining Tow Pins Pair - Silver, Spring-Loaded 4" Length

These spring action retaining pins are designed to simplify trailer and tow bar connections by eliminating loose clips. Each pin features a 1/2" diameter shaft with a total length of 4" and a usable insert length of 2-3/4", giving secure engagement while remaining easy to insert and remove. The self-retaining mechanism keeps the pin captive in the hitch or coupler so you won't misplace clips on the road.

How do these self-retaining pins make hitching faster?

The BX88219 pins use a spring-loaded detent that locks the pin in place as soon as it passes through the hitch or accessory hole. This allows one-handed insertion and removal without fumbling for separate clips or cotter pins. Their captive design reduces setup time and frustration when hitching in low-light or cramped spaces.

• Spring-loaded detent holds pin securely without an external clip.
• 1/2" shaft fits common Blue Ox tow bar holes and many aftermarket accessories.
• 4" overall length with 2-3/4" usable insert depth for confident engagement.
• Sold as a pair to replace both driver and passenger side pins or keep a spare.

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

These pins are built as a direct replacement for Blue Ox tow bars and match typical 1/2" hole systems on many trailers and hitch accessories. Measure your device's hole diameter and required insert length to confirm compatibility. If your setup requires a 1/2" diameter and up to a 2-3/4" usable insert, these pins will fit.

• Designed specifically as a replacement retaining pin kit for Blue Ox tow bars.
• 1/2" diameter matches standard tow bar and accessory holes.
• 2-3/4" usable insert accommodates common hitch thicknesses.
• Sold as a pair to cover both attachment points or provide a backup.

How durable and secure are these spring-loaded pins?

The BX88219 pins are made for towing environments where vibration and exposure are common. The spring mechanism keeps the pin retained under movement while the solid 1/2" diameter provides shear strength for typical towing loads. Their silver finish helps resist corrosion for longer service life when used with proper maintenance.

• Solid metal construction with a robust 1/2" shaft for strength under load.
• Spring detent resists vibration-related loosening during travel.
• Silver finish offers basic corrosion resistance; periodic inspection recommended.
• Sold as a matched pair to ensure consistent performance left and right.

How do I install and maintain these retaining pins?

Installation is straightforward: align the tow bar and accessory holes, compress the spring detent, push the pin through until it locks, and confirm it's retained. For upkeep, wipe clean after use, inspect the spring and shaft for wear, and lubricate lightly if sticking occurs. Replace pins if you notice excessive wear, bent shafts, or loss of spring tension.

• Insert pin through aligned holes until the spring locks it in place—no clip required.
• Inspect regularly for wear, rust, or damaged spring action.
• Clean and lightly lubricate if movement becomes stiff.
• Replace immediately if the pin bends or the spring no longer holds securely.

Who is this for: The Blue Ox BX88219 pair is ideal for Blue Ox tow bar owners, frequent campers, RVers, and anyone who wants a quicker, clip-free method to secure hitch connections. Choose these pins if you need a compact, easy-to-use retaining solution with a 1/2" shaft and roughly 2-3/4" usable length for common towing setups.
