Calculating the number of turns on the thread gauge for the thread Size M10 x 1-6H. The number of turns on thread gauge: Length of threads: 0.402 ± .015: A length without threads is 0.158- Not given on the picture, and the diameter of countersink is 0.435 / 0.437 x 90° Thread Size: M10 x 1-6H I. Minimum of turns a) Convert the pitch: 1 / 25.4= 0.03937” b) Minimum of turns: 1) Calculating first the threaded material length when the 0.402” dimension is on the minimum of its tolerance and the 0.158” dimension is in on the maximum of its tolerance: L1 = (0402 - 0.015) - (0.158+.004)=0.225” 2) Calculating the length without threads. From the dimension of countersink 0.435 / 0.439. Nominal diameter of countersink is 0.437 From the dimension of the M10-1, the max diameter for internal threads is 10 mm-converted in inch 0.393”. 3) Calculating: Minimum full length thread=L1-H=0.225 - 0.022= 0.203 Number of turns for the minimum full threads length: 0.203 / 0.0393=5.1...
