Verification Of Bolt Seating At Recommended Clamping Load

Verification of the seating of the bolt head or washer against the compression limiter at the recommended clamping load is the final assurance that the minimum length tolerance for the compression limiter will meet the recommended bolted joint requirements. Stated in formula mode:

Where:
Pc - is the load required to assure contact between the bolt head or washer and the compression limiter
Tmax - is the maximum tolerance condition of the assembly, calculated as the maximum thickness of the plastic component (Lp max) minutes the minimum length of the compression limiter (Lc min)
Ap - is the stress area of the plastic component as calculated in the previous element
Ep - is the elastic modulus of the plastic
Lp max - is the maximum thickness of the plastic component
