Selecting measurement units: metric and imperial?

For ease of specification and sourcing, design engineers often select their measurement units to match local standards, or otherwise those used by the design department or the manufacturing facility.

This simple choice at an early stage can make life a lot easier for all concerned and reduce unforced errors of transcription – saving time, saving costs.

So, to make life even easier and ensure engineers/buyers have access to their extensive range of ex-stock catalogue springs, Lee Spring has increased the number of defined metric springs in their catalogue of over 25,000 line items. 

This means that they can deliver standard metric springs anywhere in the world to clean metric dimensions in parallel to imperial sizes – not just conversions – exact metric specifications in compression, extension and torsion, constant force and instrument springs.
