FASTENER IDENTIFICATION CHART
Hardware sizes given in the illustrations throughout this manual.
If a washer or nut is identified as “washer, l/2” or “nut, i/2”, this means the inside diameter is l/2 inch
If a screw is identified as “screw, i/2 x 2”, this means the shaft diameter is l/2 inch and the shaft of the screw is 2 inches long. If a screw is identified as “screw, l/2 - 16 x 2”, the number “16” means that the screw has 16 threads per inch.
