Captive Panel Screws
PEM® brand captive panel screws are designed to help keep parts to a minimum and eliminate risks associated with loose hardware that could fall out and damage components.
Captive panel fasteners are ideal to attach metal panels or other thin material components in applications where subsequent access will be necessary.
