Captive nuts (or as they are more correctly named, 'tee nuts') have a range of uses but are more commonly used in
the RC hobby field for engine fixing (securing engine mounts to the firewall), wing fixings, and undercarriage fixing.
Also widely used in many general woodworking projects where a hard thread is required that will not pull out.

We stock a range of Metric, UNC and UNF sizes (scroll down for UNC and UNF)

All our Tee nuts are Bright Zinc Plated
