Overview
Not a beam or digital wrench, the CDI 2502MRMH is a mechanical click-style torque wrench with a micrometer adjustment and dual laser-marked scales. A spring-loaded pull-down lock ring holds the setting in place.
Dual scales in inch pounds and newton meters, a certificate traceable to NIST and a storage case make it a ready calibrated tool. The limitation is range: the top of the scale suits small fasteners, and accuracy is quoted only within the working span.
Who it's for
Technicians and bike or engine builders who need repeatable low torque with a calibration record will use the dual scale and lock ring. Anyone tightening large fasteners needs a wrench with a higher range.
Pros and cons
- Dual scale reading
- Dual direction operation
- Pull-down lock ring
- Individually serialized certificate
- Low maximum torque
- Accuracy differs by direction
- Not suited to heavy fasteners
Performance notes
A click wrench releases at the set value, so the user feels and hears the click and stops pulling. Accuracy is stated for clockwise and counterclockwise pulls and applies from a fifth of the scale upward, so low settings are the least reliable. The lock ring prevents the setting from drifting.
