SpletThe combined effect of the change of slip factor and reduction of the clamping force is estimated to cause a 15% reduction in slip resistance for oversize and short slotted holes and a 30% reduction for long slotted holes. The design formulae for slip-resistant joints reflect the reduced slip resistance by introducing a reduction factor ks.
