ISO 16047:2005 Fasteners - Torque/clamp force testing

This International Standard specifies the conditions for carrying out torque/clamp force tests on threaded fasteners and related parts.

It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898‑1, ISO 898‑2 or ISO 898‑6, having ISO metric threads with thread sizes M3 to M39. It is also applicable to the combination of other externally and internally threaded fasteners with a triangular ISO thread according to ISO 68‑1.

It is not applicable to set screws and similar threaded fasteners that are not under tensile stresses, nor to screws which form their own mating thread or threaded fasteners having additional self‑locking features.

Then we recommend our BTF series microcomputer-controlled effective torque testing machine

Product Introduction

The BTF series microcomputer-controlled effective torque testing machine is suitable for determining the tightening characteristics of external hexagonal screws under specified conditions. It is used to measure parameters such as bolt torque coefficient, k-factor, tightening torque,coefficient of total friction, coefficient of friction between threads, yield clamping force, yield tightening torque, rotation angle, ultimate clamping force, and ultimate torque. Based on the obtained total friction coefficient and thread friction coefficient, the coefficient of friction between bearing surfaces can be calculated.

This model meets the following standards:

l ISO 16047-2005 Fasteners - Torque/Clamping Force Test

l GB/T 16823.3-1997 Test Method for Tightening of Threaded Fasteners

l JIS B1186 High-strength connection washers (Simplified Chinese - Traditional Chinese )

l JB/T 9370-1999 Technical Conditions for Torsion Testing Machines

l JJG 269-2006 Verification Procedure for Torsion Testing Machines
