Features bolt tensioners

Bolt tension elongated bolt directly using pure tension, shear and lateral force without twisting, to join the contact surface without friction damage, it is the best way to precisely control bolt preload. Than is responsive, accurate, no torsional stress, no friction damage, can synchronize multiple bolt preload hydraulic torque wrenches, bolt tensioners advantages; therefore bolt tension preload in more stringent requirements for the occasion applied more widely. The disadvantage is the need to have sufficient elongation, and thus narrow axial space is very limited occasions.
