The thread form is slightly modified to increase the minor diameter, and thus the strength of screws and taps. The major diameter still extends to within 1 / 8 H of the theoretical sharp V, but the total depth of the thread is reduced 4% from 5 / 8 H = 5 / 8 cos(30°) P ≈ 0.541P to 0.52P. [5]

ISO metric threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The thread depth is 0.54125 × pitch. The outermost 1 ⁄ 8 and the innermost 1 ⁄ 4 of the height H of the V-shape are cut off from the profile.
The 5 ⁄ 32 in Whitworth threads have been the standard Meccano thread for many years and it is still the thread in use by the French Meccano Company. [ citation needed ] Fixings for garden gates traditionally used Whitworth carriage bolts , and these are still the standard supplied in UK and Australia.

Dimensions of a square thread form. The square thread form is a common screw thread profile, used in high load applications such as leadscrews and jackscrews. It gets its name from the square cross-section of the thread. [1] It is the lowest friction and most efficient thread form, but it is difficult to fabricate.
