The crimp ferrule and centre contact dimensions are matched to these 0.100-inch-diameter class coax types. If you are terminating RG-58 or RG-59, this is the wrong kit — look at the 31-320-RFX instead, which is specced for the larger RG-58 group. ## RF Performance and Mechanical Ratings The bayonet lock gives positive retention with a quarter-turn, and the 500-cycle mating life means this plug survives field-service reconnections without contact wear issues. For the crimp tool, use an Amphenol RF or compatible hex crimp die set sized for the RG-174/316 ferrule OD.","metaTitle":"Amphenol RF 31-315 BNC Plug, 50 Ohm, 4 GHz, RG-174/316","metaDescription":"Amphenol RF 31-315 BNC plug, male pin, 50 Ohm, 4 GHz, 500 V.
