🔩 WHY IS EQUAL BOLT LOAD MORE IMPORTANT THAN SIMPLY ACHIEVING THE CORRECT TORQUE?
A specified torque value does not always mean that every bolt in a joint has achieved the same clamping force. Friction, thread condition, lubrication and tightening sequence can all influence the final bolt load.
For critical bolted joints, hydraulic bolt tensioning can provide a more direct and controlled method of achieving the required bolt preload.
Consistent bolt loading can help reduce the risk of:
✔️ Fl**ge distortion
✔️ Uneven gasket loading
✔️ Excessive or insufficient bolt preload
✔️ Premature fastener failure
✔️ Joint movement and potential leaks
✔️ Unplanned maintenance and production downtime
Bolt Torque provides specialised hydraulic bolt torquing and bolt tensioning services for critical industrial applications, where controlled and accurate bolt loading is essential.
The appropriate method—torquing or tensioning—depends on the joint design, fastener configuration, access limitations and required preload.
