We can design and calculate the dimensions and loads of bolted joints for you to evaluate the current tightening method and calculate the bolt preload for the reliability and durability of the joint.Large and accurate preload loads allow the design of smaller bolt sizes, compact dimensions can reduce machine size, reduce material and processing costs.• pure tensioning screws can produce higher preload loads on the same bolts.• higher preload capacity ensures that bolt joints are not unexpectedly loose. Shorten expensive equipment maintenance cycle.• controllable, accurate, consistent bolt preload to reduce leakage or adjacent fastener load inhomogeneity.• the maximum stress of the first bolt is reduced by 50%, which increases the fatigue life of the bolt connection.• extra elasticity of th...
