1/2"-20 Fine Thread Spare Tire Mounting Hardware Kit - Zinc Bolts, Nuts & Washers
This complete spare tire mounting hardware kit includes the exact 1/2"-20 fine thread carriage bolts, lug nuts, and retaining washers commonly used on trailer spare tire carriers and mounts. Perfect for replacing lost, rusted, or worn hardware on utility trailers, cargo trailers, boat trailers, enclosed trailers, and many Load Trail, PJ Trailers, Big Tex, or similar models. Zinc plating provides excellent rust and corrosion resistance for long-lasting outdoor use.
What's Included in the Kit
- (2) 1/2"-20 x 1-3/4" zinc-plated carriage bolts – Square neck design prevents spinning during installation
- (2) 1/2"-20 lug nuts – Standard thread matches most trailer wheel lug nuts for easy use of the same tools
- (2) Retaining washers / push nuts – Secure the carriage bolts to the mount and prevent loosening
Key Benefits & Features
- Durable & Corrosion-Resistant: Heavy zinc plating protects against weather, road salt, and moisture – ideal for all-season trailer use.
- Direct Replacement: Matches original hardware on many standard trailer spare tire mounts and carriers (commonly 1/2"-20 thread).
- Easy DIY Installation: Insert carriage bolts into the mount slot, secure with retaining washers, mount the spare tire, and tighten lug nuts (recommended torque: 90-120 ft-lbs).
- Enhances Safety: Keeps your spare tire securely attached, ready for roadside changes, and prevents loss during travel.
- Versatile Compatibility: Works with most utility, cargo, equipment, landscape, and boat trailer spare tire carriers that use 1/2"-20 hardware.
Common Uses
Great for trailer owners needing quick fixes for missing or damaged spare tire bolts, upgrades for older trailers, or maintenance on fleet vehicles.
Installation Tips
- Align carriage bolts in the square holes of your spare tire carrier/mount.
- Push retaining washers over the bolt threads to lock them in place.
- Mount the spare tire/wheel assembly.
- Secure with lug nuts and tighten evenly.
Note: Always verify your trailer's bolt thread size and mount type for perfect fit. Not compatible with metric or non-1/2"-20 systems.
