Change in external load on bolt given external load and stiffness of boad

Go Change in External Load = External Force on Bolt*(Stiffness of Threaded Bolt/(Stiffness of Threaded Bolt+Combined Stiffness of Gasket and Parts))

Tensile Stress Area of Threaded fastener

Go Tensile stress area of threaded fastener = (pi/4)*(((Pitch Diameter of External Thread+Minor Diameter of External Thread)/2)^2)

Shear Stress at Core Diameter of Threaded Fastener given Tensile Force

Go Shear stress in bolt = Tensile Force on Bolt/(pi*Core Diameter of Threaded Bolt*Height of nut)

Tensile Force acting on Bolt given Shear Stress

Go Tensile Force on Bolt = (pi*Shear stress in bolt*Core Diameter of Threaded Bolt*Height of nut)

Tensile Force acting on Bolt

Go Tensile Force on Bolt = (pi*Shear stress in bolt*Core Diameter of Threaded Bolt*Height of nut)

Tensile Stress in Core Cross-Section of Bolt given Tensile Force and Core Diameter

Go Tensile stress in bolt = Tensile Force on Bolt/((pi/4)*(Core Diameter of Threaded Bolt^2))

Tensile Force acting on Bolt given Tensile Stress

Go Tensile Force on Bolt = Tensile stress in bolt*pi*(Core Diameter of Threaded Bolt^2)/4

Change in Load on Bolt given Resultant Load and Initial Preload in Bolt

Go Change in External Load = Resultant load on bolt-Initial preload in bolt due to tightening of nut

Initial Preload in Bolt due to Tightening

Go Initial preload in bolt due to tightening of nut = Resultant load on bolt-Change in External Load

Resultant Load on Bolt

Go Resultant load on bolt = Initial preload in bolt due to tightening of nut+Change in External Load

Shear Stress at Core Diameter of Threaded Fasteners given Tensile Yield Strength

Go Shear stress in bolt = Tensile yield strength of bolt/(2*Factor of Safety for Bolt)

Tensile Stress in Core Cross-Section of Bolt given Tensile Yield Strength

Go Tensile stress in bolt = Tensile yield strength of bolt/Factor of Safety for Bolt

Tensile Yield Strength of Bolt

Go Tensile yield strength of bolt = Factor of Safety for Bolt*Tensile stress in bolt

Shear Stress at Core Diameter given Shear Yield Strength of Threaded Fastener

Go Shear stress in bolt = Shear yield strength of bolt/Factor of Safety for Bolt

Primary Shear Force on each Bolt

Go Primary shear load on bolt = External Force on Bolt/Number of Bolts in Joint

External Force on Bolt

Go External Force on Bolt = Number of Bolts in Joint*Primary shear load on bolt

Ultimate Tensile Strength of Bolt

Go Ultimate tensile strength of bolt = 2*Endurance limit of rotating beam bolt specimen

External Force on Bolt Formula

External Force on Bolt = Number of Bolts in Joint*Primary shear load on bolt
P_ext = n*P₁'

What is a fastener?

A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.
