It is often necessary in the design of mechanical assemblies to attach two sheet metal parts perpendicular to one another so that no metal to metal contact occurs. This usually requires a separate fastener and a molded rubber grommet. This invention achieves this function with a single die cut rubber part. Fig. 1 shows the rubber fastener/isolator where part A is a stamped sheet metal part that is to be attached perpendicularly to part B. The required contours of the sheet metal parts are easily formed by normal die stamping methods. The rubber fastener/isolator is also formed using die cutting techniques. The object of this invention is to secure two sheet metal parts and provide shock and vibration isolation between them in a simple and inexpensive manner.
