Rack Solutions M6 x 16mm Pan Head Phillip Drive Screw 50-Pack - 50 / Pack

Rack screws are used to attach equipment to the vertical uprights of a 19" rack. Racks do not have a standard thread type. There are three common thread types for rack screws: 10-32, 12-24 and M6. Since the introduction of the square hole rack and Cage Nuts, the exact thread can be selected and changed at will. M6 refers to a metric 6mm screw. The outside diameter of the threads is 6mm. The standard metric rack screw is actually an M6 x 1mm. The number "1mm" refers to 1 threads per millimeter. M6 screws are commonly used by HP. You can identify an M6 screw by measuring the diameter with a ruler at slightly more than 7/32" (0.228").
