Parts Desk Insights
Best Use Case: Ideal when you want a simple threaded eye securement/lifting point and you already have (or are using) matching 5/16"-18 threaded rod stock or bolts.
Common Issues: Confirm you have the correct thread standard (5/16"-18 UNC) before installation, and ensure the mating bolt/rod is fully engaged for a secure hold. If you’re working on a transom/bulkhead installation, verify the stack-up thickness and consider related hardware and sealing as needed for your specific setup.
