Snap-on QD2R100 3/8" Drive Torque Wrench 20–100 Nm
Model: QD2R100
The Snap-on QD2R100 is a 3/8" drive click-type torque wrench covering 20–100 Nm, widely used in Thai automotive assembly. Its positive click mechanism provides clear audible and tactile feedback at the set torque, preventing overtorque damage to bolts and studs. ±4% accuracy per ISO 6789 Type I Class C suits engine assembly, brake systems, and wheel fastening applications. Calibration is performed on a traceable torque calibration bench, recommended annually or every 5,000 cycles.

Frequently Asked Questions
How often should a torque wrench be calibrated?+
Every 12 months or every 5,000 cycles per ISO 6789, whichever comes first. Immediate recalibration is needed after dropping, impact, or suspected deviation.
Is ±4% accuracy sufficient for engine component assembly?+
For most OEM assemblies with ±10–15% torque tolerance, yes. Parts requiring tighter tolerance such as some cylinder head bolts may need a Grade A torque wrench (±2%) or an electronic torque multiplier.
How should a torque wrench be stored to maintain accuracy?+
Return to the minimum scale setting (not zero) after each use, store in its case, never use it as a breaker bar, and never use pipe extensions on the handle.
