⚡ At a Glance
- • Torque Range: 5-25 Nm micrometer-style adjustment for light to medium fastenings
- • Best for: Automotive maintenance, bicycle servicing and general workshop fastening tasks
- • Not ideal for: High-torque industrial jobs requiring torque beyond 25 Nm
Micrometer-style torque wrench covers 5–25 Nm with clear dual Nm and lb.ft scales. Simple, precise torque setting suited to workshop fastening tasks.
Smooth ratchet action, with flip-reverse Chrome Vanadium steel head
Flip-reverse ratchet head made from Chrome Vanadium steel uses a smooth-action mechanism to change direction quickly while maintaining engagement on the fastener. The micrometer-style adjuster allows fine torque selection without loose play.
Fast direction changes and steady engagement speed up repetitive jobs and reduce slippage risk. Clean, decisive turning makes delicate fastenings easier to control.
Secure grip and control, with aluminium knurled handle
Knurled aluminium handle improves grip in oily or wet conditions and balances the tool for controlled wrist movement. The textured surface reduces the chance of slipping during torque application.
Firm handling increases confidence when working in tight spaces or when applying repeated torque settings. Reduced hand fatigue during longer jobs keeps accuracy consistent.
Traceable accuracy, with individual test certificate
Each tool is individually tested to a ±4% accuracy tolerance and issued with a uniquely numbered test certificate, with calibration tolerance aligned to BS EN ISO 6789-1:2017. Scales are graduated in both Nm and lb.ft for straightforward reading.
Reliable, certified accuracy supports consistent builds and maintenance checks, making the wrench suitable where traceability matters. Clear dual scales cut down on conversions and measurement errors.
