172317 is an N-type shoring plug connector manufactured by Amphenol Connex, designed for RF and microwave applications requiring a secure threaded connection. The connector features a 5/8-24UNF-2B thread specification with brass construction and precision-finished surfaces to ensure reliable electrical contact and mechanical stability. Key dimensional specifications include a length of 21.00 mm (0.827 inches) and a diameter of 17.00 mm (0.670 inches), with a 5.0 mm (0.20 inch) feature dimension. The brass material with controlled finish tolerances (1.180" - 1.140" = 0.020" and 0.020" = 0.007") provides excellent corrosion resistance and durability. This shoring plug is commonly used in RF test equipment, antenna systems, and transmission line applications where impedance matching and signal integrity are critical.
