Bolt & Fastener Testing
Overview
Standards-Based Fastener Analysis — M12 to M36
The Computer Control M12-M36 High Strength Bolt Torque Coefficient Tester — NCMC-2000SE microcomputer-controlled fully automatic thread analysis and testing system — maps directly to ISO16047, ISO2320-2008, GB/T16823, GB/T 3098.9-2010, GB/T16823.3-2010, ISO 2320, ISO 261, and GB/T228.1-2010 controller design requirements.
Developed under Fastener Industry Association commission, NCMC-2000SE data are recognized by metrology agencies, testing agencies, and bolt manufacturers — breaking reliance on imported equipment through in-house software, measurement, and hardware.
What NCMC-2000SE Measures
One floor-standing cabinet (human-factors layout) covers:
- Axial force (clamping force), total torque, preload
- Thread torque, support surface torque
- Total / thread / support surface friction coefficient
- K coefficient, yield limit torque and axial force
- Breaking torque axial force, tightening angle
Tests include equal-rate loading, equal-rate torsion angle, sectional torque and angle control with smooth mode switching. Real-time curves and printable reports on PC.

Controller and M12-M36 Fixture Notes
NAICE TEST DSP controller (FPGA + ARM, Ethernet TCP/IP) supports multi-channel ±10V analog and encoder inputs for automotive fatigue-grade closed-loop speed.
Main machine: Japan-import AC servo motor and drive, reducer, dynamic torque sensor, load sensor, static torque sensor, guide rail. Safety load 150% rated; linear error 0.3% FS forward/reverse.
For M12-M36 programs, verify sleeve set and jaw replacement tools in the random tool kit before running ISO16047 friction sequences.
Buyer FAQ — NCMC-2000SE
