Otoolling 1/2" Trailer Hitch Pins with R Clips — 10-Set Galvanized Replacement Pack, 4" Usable Length

These Otoolling replacement sets include 10 galvanized 1/2" box blade shank pins with matching R clips, built to secure trailer hitches, box blades and axles on tractors, trucks and large mowers.

When a hitch pin or clip fails it can stop work and create safety risks; Otoolling supplies ten replacement 1/2" pins and spring-style R clips in one pack so you have spares ready for routine maintenance or emergency swaps. Made of galvanized steel with a gold finish, each set is sized to fit most box blade shanks and receiver-style attachments, offering a straightforward, no-weld replacement option.

Will these pins fit my box blade or trailer receiver?

Most common box blade shanks and receiver tubes use a 1/2" diameter pin hole, and these Otoolling pins are designed around that standard. Confirming the diameter and usable length on your equipment helps ensure a correct fit.

• Pin diameter: approximately 1/2" (0.5 in).
• Usable pin length: around 4 inches; total length about 5 inches.
• Works with ball mounts, box blade shanks, and many receiver-style hitches.
• Suitable for tractors, trucks, trailers, and large lawn mowers when hole size matches.

How durable are the Otoolling pins and clips for outdoor use?

These pins are manufactured from galvanized steel to resist surface rust and extend service life under exposed conditions. They’re intended for general-purpose heavy-duty use rather than specialized corrosion environments.

• Galvanized finish increases corrosion resistance for routine outdoor work.
• Gold-colored coating helps visibility in low light and during fast swaps.
• R-style clips expand when inserted, locking the pin without welding or complex tools.
• Recommend occasional lubrication (grease) where friction occurs to prolong function.

How do I install and secure these trailer hitch pins safely?

Installation is quick and tool-light: slide the pin through aligned holes in the receiver and the shank, then insert the R clip through the small hole at the pin’s end until it snaps into place. The clip’s spring action helps prevent accidental disengagement.

• Remove the old pin, align the pin holes, push the pin through both holes.
• Insert the included R clip into the pin’s small end hole to lock it.
• No welding required; suitable for field repairs and fast replacements.
• Keep pins away from children and handle pointed ends carefully.

What quantity and extras come in the package?

The pack contains ten complete sets — each includes one 1/2" pin and one R clip — providing multiple spares for maintenance cycles or sharing across machines. This bulk approach reduces downtime and keeps spare parts on hand.

• Package: 10 sets of pins and R clips (10 pins + 10 clips total).
• Color: gold-toned galvanized finish for visibility and corrosion resistance.
• Material: galvanized steel for everyday durability.
• Note: slight size and color variance possible due to manufacturing and screen display.
