High strength bolt nut fasteners torsion testing machine

Model: TBW

TBW series bolt torsion testing machine is mainly used to check the material performance of bolts nuts, double-screw bolts etc., fastener and connection pairs of various grade 12.9, 10.9, 9.8, 8.8. Can measure the preload, fastening axial force F, yield fastening axial force, yield clamp force, limit clamp force, safety load, breaking load, torque T, angle etc., Conform with standard: ISO 16047, EN 14399-2, DIN2510/5, DIN2510/6, ASME/ASNIB18.2.2, ASTM.A320/A320M, ASTM A325, ASTM A354. 

Can get the 3 kinds data curve report: torsion angle - torque, torque – lock force, extension rate – lock force, torque curve, according the measuring data, can calculate to get the torque coefficient and friction coefficient.
