Retainers are cylindrical fasteners which are pressed or swaged into a panel, and have a center hole that is either threaded or drilled through. The fastener allows a screw to be held in the panel so that it is not lost when loosened. These are typically paired with captive panel screws and can also accommodate a spring if required.
Retainers are typically made of stainless steel or aluminum and can be 100% modified to customer specifications. Standard sizes range from 4-40 to 3/8 thread and overall length up to 9/16”. Swaging and flaring tools are also available from ASM to match each retainer.
