Core Diameter of Studs

Go Core Diameter of Cylinder Head Stud = sqrt(Inner Diameter of Engine Cylinder^2*Maximum Gas Pressure inside Cylinder/(Number of Studs in Cylinder Head*Tensile Stress in Cylinder Head Studs))

Net Resisting Force Offered by Cylinder Head Studs

Go Resisting Force by Cylinder Head Studs = (Number of Studs in Cylinder Head*pi*Core Diameter of Cylinder Head Stud^2)/4*Tensile Stress in Cylinder Head Studs

Thickness of Cylinder Head

Go Thickness of Cylinder Head = Inner Diameter of Engine Cylinder*sqrt(0.162*Maximum Gas Pressure inside Cylinder/Circumferential Stress in Engine Wall)

Pitch Circle Diameter of Studs given Pitch and Number of Studs

Go Pitch circle diameter of engine studs = Number of Studs in Cylinder Head*Pitch of engine studs/pi

Pitch of Englne Cylinder Head Studs

Go Pitch of engine studs = pi*Pitch circle diameter of engine studs/Number of Studs in Cylinder Head

Pitch Circle Diameter of Studs

Go Pitch circle diameter of engine studs = Inner Diameter of Engine Cylinder+3*Nominal Diameter of Cylinder Head Stud

Maximum Pitch of Studs for Cylinder Head

Go Pitch of engine studs = 28.5*sqrt(Nominal Diameter of Cylinder Head Stud)

Minimum Pitch of Studs for Cylinder Head

Go Pitch of engine studs = 19*sqrt(Nominal Diameter of Cylinder Head Stud)

Core Diameter of Studs given Nominal Diameter

Go Core Diameter of Cylinder Head Stud = Nominal Diameter of Cylinder Head Stud*0.8

Nominal Diameter of Studs

Go Nominal Diameter of Cylinder Head Stud = Core Diameter of Cylinder Head Stud/0.8

Minimum Number of Studs for Cylinder Head

Go Number of Studs in Cylinder Head = 10*Inner Diameter of Engine Cylinder+4

Maximum Number of Studs for Cylinder Head

Go Number of Studs in Cylinder Head = 20*Inner Diameter of Engine Cylinder+4

Nominal Diameter of Studs Formula

Nominal Diameter of Cylinder Head Stud = Core Diameter of Cylinder Head Stud/0.8
d = d_c/0.8

Advantages of Studs

Studs provide the ability to obtain much more accurate torque values because the studs don't twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.

How to Calculate Nominal Diameter of Studs?

Nominal Diameter of Studs calculator uses Nominal Diameter of Cylinder Head Stud = Core Diameter of Cylinder Head Stud/0.8 to calculate the Nominal Diameter of Cylinder Head Stud, The nominal diameter of studs is the diameter equal to the external diameter of the threads or the overall diameter of the part. Nominal Diameter of Cylinder Head Stud is denoted by d symbol.

How to calculate Nominal Diameter of Studs using this online calculator? To use this online calculator for Nominal Diameter of Studs, enter Core Diameter of Cylinder Head Stud (d_c) and hit the calculate button. Here is how the Nominal Diameter of Studs calculation can be explained with given input values -> 23125 = 0.0185/0.8.
