STANDARD TOLERANCES

Use these tolerances as a general guide. Solon manufactures a wide variety of springs and washer sizes that meet different tolerance requirements. For actual tolerances for a specific part, contact us.

ID = +1.5% of the ID Min
OD = -1.5% of the OD Max
Thickness = +/-5% of the Thickness
Overall Height (H) = +/-10% of the Overall Height
Deflection (h) = +/- 10% of the Deflection
Flat Load = For SDS springs refer to DIN specification for tolerances. For load-deflection tolerance information for other parts, please contact Solon Engineering.

UNITS OF MEASURE

IMPERIAL                                                                   METRIC
Dimensions = inches                                             Dimensions = millimeters
Load = pounds force                                              Load = Newton
Torque = foot-pounds                                          Torque = Newton-meters
Temperature = °F                                                    Temperature = °C
 

TORQUE CALCULATION

The widely accepted formula is as follows,
 
T = K*F*D
 
where,
 
K = Estimated nut friction factor
T = Bolt torque
D = Nominal bolt diameter
