Buying Guide

Key purchase considerations

  • Thread standard: Most 5-lug hubs use 1/2″-20 bolts; verify the thread pitch on your hub before buying.
  • Length and engagement: A 1-5/8″ overall length with a 7/8″ threaded portion provides ample thread engagement for stable mounting.
  • Material and finish: Solid steel with zinc plating offers corrosion resistance in marine and outdoor environments.
  • Hub compatibility: Double-check hub bore and bolt pattern, and ensure compatibility with your trailer model (boat, utility, mobile home, etc.).
  • Quantity and replacement cycles: Choose pack sizes that match your replacement needs to avoid reordering soon after installation.

What to check before buying

  • Hub type: Confirm you have a 5-lug hub and the bolts match your hub’s thread specifications.
  • Environment: If you’re in saltwater or high-humidity areas, prioritize zinc-plated or galvanized finishes.
  • Installation: Ensure the hex head size (13/16″) is compatible with your wrench and can achieve proper torque.

Who should consider these bolts

  • Boat trailer owners needing reliable, corrosion-resistant replacements.
  • Utility trailer users seeking durable, easy-to-install bolts.
  • Mobile home trailer operators wanting a broadly compatible bolt option for wheel hub assemblies.
