While this means there is much less thread securing the fastener, Emuge says that thread strength is comparable to conventionally machined threads from a depth of thread of 2xD.
This research aims to comprehend further the mechanism of the thread connection with respect to the depth of thread penetration.
The main parameter is the depth of thread penetration.
The first experiment was done to find early estimation of correlation between the depth of thread penetration and the maximum strength of thread connection system.
The diameter of lower rod was double the diameter of the upper rod in order to eliminate the effect of the lower rod on the depth of thread penetration.
Thread failure occurred as the depth of thread penetration is less than 15 mm (specimen number 1, 2, 5, and 6).
The rod failure occurred if the depth of thread penetration was more than 15 mm (specimen number 3, 4, 7, and 8).
In order to yield nominal tension strength, the minimum depth of thread penetration is 15.8 mm (specimen number 7), which is equal to 90.3% of the thread minor diameter.
It is can be summarized that the maximum load of thread connection is greater until the number of thread to 10 (the depth of thread penetration is approximately 90% of thread minor diameter).
The minimum depth of thread penetration (number of thread) resulting the nominal tension strength is 90% from the rod minor diameter.
Other pluses deliver a depth of thread multiplied up to three times the thread diameter (minimum diameter 1.3 mm), precise control of thread depth and diameter, a thread free of burrs and chips, and threading done to within one thread pitch of the bottom of the hole.
Maybe I've made some of you uncomfortable by mentioning the depth of threads and not turning them overly deep.
