The load ring must be placed in the direction of pull before loading - do not turn under load. For more details please have a look into our user manual.
To calculate the necessary thread length (L):
L = H + S +K + X
H = Material height
S = Thickness of the washer
K = Height of the nut (depending on the thread size of the screw)
X = Excess length of the screw (twofold pitch of the screw)
L max. = n max.
pewag provides, along with the standard and maximum thread lengths, specially customised thread lengths. Supplied customised and maxium thread lengths include a washer and a crack-tested, corrosion-proofed screw nut.
