A common rule of thumb is to provide a minimum length of thread engagement equal to the major diameter of the fastener A more conservative rule of thumb is to use a thread engagement length of 1 1 2 times diameter
May 21 2019 nbsp 0183 32 Preload The general rule of thumb for bolted joint design steel fasteners is for the fastener to be engaged by between 1 and 1 5 times the diameter of the fastener used softer material fasteners will need a longer engagement length

Oct 03 2020 nbsp 0183 32 Minimum Thread Engagement Generally the minimum thread engagement length for a joint is determined such that the full tensile strength of the bolt is utilized prior to shearing of nut threads In other words it is expected that the shear failure occurs in the fastener part often externally threaded and the failure occurs only after
The following illustration demonstrates the pitch diameter allowances on a 3 4 10 bolt and nut The axial distance through which the fully formed threads of both the nut and bolt are in contact is called the length of thread engagement The depth of thread engagement is the distance the threads overlap in a radial direction
