ABSTRACT:
A fastener for securing a circuit board to a chassis or another circuit board of an electronic appliance in a spaced relationship by a predetermined fixed distance. The fastener comprises a plunger having an inverted pyramid-shaped head and a rod extending downwardly from said head, and a fastener body including an isolating member having at the center thereof an opening for receiving said plunger therein and a pair of locking members located at the opposite ends of said isolating member with a pair of support plates interposed therebetween. When the plunger is inserted into the fastener body, the locking members are expanded outwardly by the plunger so that a circuit board and a chassis or another circuit board are secured to each other in a predetermined spaced relationship.
