Screw Clearance Test

Available VariantsNominal Thread DiametersThere are eight different thread sizes available based on the ISO standard for metric threads. (Naming convention: M<diameter in mm>, here the pitch im mm is given in brackets)M4 (0,7)M6 (1)M8 (1,25)M10 (1,5)M16 (2)M20 (2,5)M24 (3)M30 (3,5)Screw LengthsFor each thread diameter there are four lengths of screws provided. (Naming convention: M<nominal diameter in mm>L<screw length in mm>, if there is no length given then the length of the screw is equal to the nominal diameter)Clearances (Nuts)For each thread diameter there are hex nuts with four levels of clearance provided. The amount of clearance is indicated by the number of dimples along the nut's perimeter.
