M10-M20 Bolt Friction Coefficient Tester Bolt Testing Equipment High-Strength Bolt Tester Intelligent Detection of Torque/Axial Force/Friction Coefficient
Bolt & Fastener Testing
Overview
Friction Coefficient Focus for M10–M20 Fasteners
The M10-M20 Bolt Friction Coefficient Tester — NCMC-2000SE bolt testing equipment for intelligent detection of torque / axial force / friction coefficient — serves tier suppliers and independent labs working M10 and M20 (and intermediate sizes within fixture range) before parts reach OEM assembly lines.
Same NCMC-2000SE platform as larger-span listings, but this page stresses high-strength bolt tester workflows where total friction coefficient, thread friction coefficient, and support surface friction coefficient must be separated for coating, lubricant, and plating approvals.
Who Runs M10–M20 Tests Daily?
Typical users:
- Automotive and machinery fastener suppliers — lot release on ISO16047 / GB/T16823 friction programs
- Galvanizing and coating houses — compare K coefficient before and after surface treatment
- Third-party test houses — accredited reports using ISO2320-2008, GB/T 3098.9-2010, GB/T16823.3-2010, ISO 2320, ISO 261
CHENJI (Jinan Chenji International Trade Co., Ltd.) provides floor-standing cabinet layout for easy load/unload of M10-M20 specimens into the 800mm test space.

Sample Mounting and Thread Preparation
- Select M10-M20 jaw/fixture set from special bolt fixture (NAICE)
- Clean threads and bearing surfaces per customer ISO16047 procedure
- Program equal-rate loading or equal-rate torsion angle — sectional torque/angle switching supported
- Capture preload, thread torque, support surface torque for friction split
- Print curve and report; optional simulated working condition (4-3) for assembly validation
Human-factors cabinet height reduces bending when loading small-diameter bolts repeatedly.
Reading K-Coefficient and Friction Splits
The system calculates K coefficient with axial force and total torque channels aligned. 4-4 Attenuation detection tracks axial force decay — useful for elastomer under-head inserts and soft coatings on M10-M20 trials.
4-5 Yield tightening and 4-6 Tightening damage extend the same M10-M20 setup to R&D without retooling the 2000Nm head.
Frequently Asked Questions
Is hardware different from the M12-M36 listing?
NCMC-2000SE host is shared; difference is marketed M10-M20 fixture emphasis and QC use case.
Imported vs domestic control?
Independent R&D on software and NAICE TEST hardware; GB/T228.1-2010-oriented DSP controller.
Quote and English software?
