Captive hardware is a class of fasteners that are designed to lock into place using a screw and is often used in products with difficult-to-reach locations where a wrench cannot be used to hold the fastener in place. Also known as captive fasteners, this category of fastener is generally installed inside a hollow tube or channel into which a screw is inserted and tightened.
Captive hardware comes in a variety of designs and materials, but virtually all of them feature some sort of serrated edge or protruding teeth that causes the hidden nut to expand and seat itself into the surrounding material. These serrated edges are machined directly into the surface of the nut to provide a solid bite onto the product being connected. If you’re in the market for these types of products, search no further than Electronic Fasteners, located in Canton, MA.
Before the development of this captive hardware, a product required an access hole to tighten parts into place. This not only affected product design and looks, but it also could create a structural weakness in products – a serious issue for critical applications such as automobiles and other products that could cause serious injury or even death if fastener failure occurred. The development and use of this hardware have enabled manufacturers to design products that do not need access channels and, as a result, are less susceptible to structural weakness. The automotive product aftermarket is one major consumer of this hardware; in particular, a captive fastener system that features a spring clip and a male fastener that grabs onto the clip and locks tight to it.
