Husqvarna 872110510 Carriage Bolt 5/16-18

Product Description

The HUSQVARNA 872110510 is a genuine OEM carriage bolt used in Husqvarna outdoor power equipment. Carriage bolts feature a smooth, rounded head and a square neck beneath the head that resists turning during installation, making them well suited for fastening components in wood, metal, and composite assemblies. This bolt is threaded at 5/16-18, meaning a 5/16-inch nominal diameter with 18 threads per inch on a unified coarse (UNC) thread pattern. It is the correct replacement when the original factory fastener is lost, damaged, or needs replacement during routine service or repair.

This carriage bolt is intended for use in Husqvarna equipment assemblies where the OEM specification calls for a 5/16-18 fastener. Typical applications include deck, frame, and structural panel attachments found on Husqvarna lawn tractors, zero-turn mowers, and similar outdoor power equipment. Using the genuine OEM part ensures the correct thread engagement, head geometry, and material grade required by the original design.

Key Features

• Genuine Husqvarna OEM replacement fastener
• 5/16-18 UNC thread pattern for reliable thread engagement
• Rounded carriage bolt head resists surface damage to mating components
• Square neck under head locks bolt in place during nut tightening

Compatibility

Designed as a genuine OEM-spec replacement carriage bolt for Husqvarna outdoor power equipment requiring a 5/16-18 fastener. Consult your equipment's parts diagram to confirm this MPN is listed for your specific model before ordering.

Installation Notes

Fastener replacement is typically performed by a qualified equipment technician or experienced DIYer using standard hand tools. Disengage all blades, remove the ignition key, and disconnect the spark plug wire before accessing any mechanical fastener on the equipment. Insert the bolt from the correct side per the parts diagram so the square neck seats fully into the mating hole before threading the nut. Do not overtighten, as over-torquing a carriage bolt can strip the square-neck seat or damage surrounding material.
