Red Headed Hitch Pins for Towing
These Grade 5 steel pins measure 5/8 inch by 4 inches and carry part number 51135. They are designed to secure a trailer to a vehicle in automotive, agricultural or lawn-care settings. The red head provides visible confirmation that the pin is seated. This hardware suits owners who need a straightforward replacement pin for existing hitch hardware.
Grade 5 Shear Strength Defines the Limit
The fastener meets Grade 5 specifications, which set its maximum shear and tensile capacity. Loads that exceed this rating can cause the pin to deform or snap during use. The steel construction resists wear but does not compensate for an undersized pin hole or excessive tongue weight. Buyers must match the pin grade to the hitch class and trailer demand.
Verify Pin Diameter and Usable Length First
Confirm that your hitch receiver and drawbar accept a 5/8 inch diameter pin before ordering. Measure the distance between the hole centres to ensure the 4 inch overall length provides enough engagement on both sides. A pin that is too short will not lock; one that is too long may interfere with surrounding components. This item ships directly from the manufacturer and orders of 75 or more ship free.
