Grounding snaps are used to connect a ground cord to a work surface static safe mat or a ESD floor mat. An antistatic floor mat or ground mat is one of a number of antistatic devices designed to help eliminate static electricity. It does this by having a conductive material embedded within the mat that collects the static. The mat would need to be grounded (earthed). This is usually accomplished by plugging into the grounded line in an electrical outlet.Pronged Push and Clinch snaps are ideal for multi-layered surfaces and come as a male stud or female socket and are offered in 10 mm (3/8) size.
