Best for: Budget-conscious boat trailer owners replacing 5-lug hub bolts. These bolts offer solid steel construction with a zinc-plated finish to resist corrosion in marine environments. The 1/2″-20 thread and 13/16″ hex head provide reliable engagement, with a 7/8″ threaded section for sturdy connection. Use when you need a straightforward replacement kit for standard 5-lug hubs.
- 1/2″-20 fine thread
- Overall length: 1-5/8″
- 13/16″ hex head; 7/8″ threaded portion
Caution: Confirm your trailer hub thread specifications before ordering to ensure compatibility with your specific hub.
10 Pack 11062A Trailer Lug Bolts 1/2″-20 x 1-5/8″
Best for: Teams or individuals stocking spare bolts for multiple trailers or ongoing maintenance. The same durable specs as the smaller pack make it a practical choice for fleets or regular boat trailer upkeep.

Buying Guide
What to consider when buying boat trailer lug bolts
- Thread size and length: For 5-lug hubs, 1/2″-20 with a total length of 1-5/8″ is common. Confirm hub thread type and required engagement with your trailer’s hub.
- Material and finish: Marine-grade zinc plating offers corrosion resistance in saltwater and wet environments. Solid steel provides strength, while stainless options resist rust over time.
- Head size: A 13/16″ hex head is typical for good torque transfer. Ensure your lug wrench or impact tool matches head size.
- Pack size: Choose packs that fit your maintenance rhythm. Larger packs save time for fleets; smaller packs suit occasional replacements.
- Compatibility: While most 5-lug hubs use the 1/2″-20 thread, always verify hub thread specifications before purchasing to avoid mismatches.
FAQ
- Q: Are these bolts suitable for saltwater use?
A: Yes, the marine-grade zinc finish helps resist corrosion in marine environments, though regular inspection is advised. - Q: How do I confirm hub thread specifications?
A: Check your trailer’s hub documentation or measure the existing bolts for thread size and pitch (1/2″-20 is common for 5-lug hubs). - Q: Can I use these bolts on non-boat trailers?
A: They are designed for boat trailers but can be used on other trailers with matching thread size and hub type, provided installation specs are followed. - Q: What is the benefit of a zinc-plated finish?
A: Zinc plating provides corrosion resistance, extending bolt life in harsh outdoor and marine environments. - Q: Should I replace all lug bolts at once?
A: For safety and uniform performance, replacing all bolts on a wheel hub at the same time is recommended if wear or corrosion is present. - Q: Do these bolts require any special installation torque?
A: Follow the trailer manufacturer’s torque specs; improper torque can lead to loosening or overtightening.
