Hydraulic bolt tension meter for torque coefficient evaluation or strength test of bolts.

BTM400K

B-BTM13K

Application

  • For study torque method as tightening method.
  • Strength test of bolted joints.
  • Capacity test of power driven fastener.
  • For training and education of torque tightening (visibility).

Features

  • Standard measuring device to test bolt and tightening characteristics.
  • With torque wrenches, bolt strength and torque coefficient of the bolt can be tested for variety of use.
  • Hydraulic mechanism is superior in durability, and the internal shock absorber allows for impact wrench use.
  • B-BTM provides one set of bush and plate as standard accessory which matches the standard bolt to be measured.
  • Compact and lightweight BTM400K can be carried to the worksite such as construction field to check the bolt tension of torsia high tension bolts.
