Core keywords	Fastener tension and torsion testing machine Locking torque tension and torsion testing machine High lock nut tension torsion testing machine
Product function and purpose	It is suitable for the tensile and torsion performance test of high lock nuts. The test content includes the tightening torque, the unscrewing torque, the pre-tightening force and the loosening torque. The locking torque refers to the maximum torque during screwing in, and the value area can be set; the loosening torque refers to the rotating torque under no axial load, that is, the maximum or minimum torque in a screw-out area, and the value area can be set . The total friction parameter µtotal, thread friction parameter µ thread, end face friction coefficient µ end face, tightening coefficient K and other parameters can be obtained.
According to the standard	1. The testing machine is manufactured according to JB / T 9370-1999 "Specification for torsion testing machine".
	2. The testing machine is tested according to GB / t10128-1998 "metallic materials torsion tensile test method at room temperature", gjb715.13 "pre tightening test method for assembled fasteners", mil-std-1312, Test16 "pre tightening test method" and other standards to provide data.
	3. The testing machine can also be tested according to the European standards such as en-14399-1:2005, en-14399-3-6:2006 and ISO 898-1:1999.
