Finding appropriate bolt torque when bolt bolt is used on PVC surface
I am currently bolting a sheet of PVC to a steel frame.
For an M6 8.8 bolt the standard torque is 9.3Nm, according to various
However Im not sure if this takes into consideration the strength of the bolted material. Im a little worried that the PVC may be damaged by the clamping force (The compressive strength of the material is 67MPa). According to my calculations the clamping force and washer area would lead to a stress of 24 MPa.
My concern is the factor of safety could be too low.
Are there any standards that help the user find what bolt torque should be applied with the bolted material properties taken into consideration.
