The length of engagement of a bolt in an insert is generally determined by strength properties. The engineering practice of balancing the tensile strength of the bolt material against the shear strength of the boss material also applies to helicoil inserts.
Helicoil Length Calculator:
Note : When parent material shear strength falls between two tabulated values, use the lower of the two.
Note: The parent material shear strengths are for room temperature. Elevated temperatures significantly reduce
shear strength values; compensation should be made when required.
Note: Bolt thread length, overall length, insert
length, and full tapped thread depth must be adequate
to insure full thread engagement when assembled in
order to comply with its design function.
