The SCS SNAPSOCKET3/8 Snap Fastener 10mm Female Socket 10/Pack is used to connect a ground cord to a static mat. Socket snaps are held in place by crimping the tip of an eyelet through the center of the socket with a snap tool. This traps the mat between the socket on the top of the mat and the eyelet on the back of the mat. Nickel plated brass snaps provide electrical connection and a long service life.
