5 Pack 11062A Trailer Lug Bolts 1/2″-20 x 1-5/8″
Best for budget-conscious buyers replacing a small batch of bolts on a 5-lug boat trailer hub. These solid steel bolts use marine-grade zinc to resist corrosion, with a 1/2″-20 fine thread and 7/8″ threaded section for strong engagement. The 13/16″ hex head allows solid wrenching in tight spaces. They are a practical replacement kit for standard 5-lug hubs, but verify hub thread specifications before purchasing.
Best-for: Replacement bolts for boats and utilities with 5-lug hubs that use 1/2″-20 bolts. Better for: Standard trailers where corrosion resistance is required by marine environments. Caution: Confirm hub thread compatibility; incorrect matching can compromise security.

This bulk option is ideal for fleet owners or frequent trailer users who want spare bolts on hand. It shares the same specifications as the 5-pack: 1/2″-20 fine thread, 1-5/8″ length, and marine-grade zinc finish. The larger quantity reduces the need for frequent reordering and supports scalable maintenance for multiple trailers.
Best-for: Owners managing multiple trailers or needing spares. Better for: Ensuring quick replacements during roadside maintenance. Caution: Store bolts dry and organized to avoid rust over time.

Buying Guide
- Hub compatibility: Confirm your trailer hub’s thread size (commonly 1/2″-20) and the overall bolt length (1-5/8″) to ensure a secure fit.
- Material and finish: Marine-grade zinc plating resists corrosion in saltwater and humid environments. For critical exposure areas, stainless steel options may offer longer life, though cost can be higher.
- Quantity needs: If maintaining a fleet or multiple trailers, buying packs of 10 or more can reduce maintenance time, but verify that you won’t exceed fits on your hubs.
- Installation considerations: Use proper torque specifications and ensure threads are clean before installation to prevent cross-threading and ensure reliable engagement.
- Limitations to watch: Some listings do not specify hub compatibility beyond “5-lug.” Always cross-check with your trailer’s hub model to avoid mismatches or installation issues.
FAQ

- Are these bolts suitable for saltwater trailers? Yes, the marine-grade zinc finish is designed to resist corrosion in marine environments, though regular inspection is advised.
