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 the push nut assembly increases the fatigue life of bolted connections.
• easy to install in confined space, save space.
• able to quickly complete installation in a short time, saving time.
• the required torque is small, it is very convenient to check the tightness of the connection.
• simple hand tools, very safe. Avoid potential hazards caused by large tightening tools.
• multiple workers can work together to facilitate symmetric crossover tightening.
• pure tension fastening eliminates the usual thread clamping with torque tightening method.
• easy disassembly reduces the cost of costly downtime due to conventional bolt tightening.
• manual preload can resume its preload under any condition; can be reused.
