Captive nuts (or as they are more correctly named, 'tee nuts') have a range of uses but are more commonly used in the hobby for engine fixing (securing engine mounts to the firewall), wing fixings, and undercarriage fixing. 

UNC and UNF sizes now also available from stock - see lower down this page

To order, click on the 'Add to Order' button alongside the item of your choice. You can select the quantity on the order form (default is 1). To continue ordering other items, use the 'Back' button on your browser - the order form will retain the information until you are ready to submit your order.

Surface finishes are indicated by Z/P= zinc plated, S/C = self colour

Some sizes have 2 flange size options. A larger flange will give higher torque resistance whereas the smaller flange option may be preferred where space is limited or the inserts are close together.
