Keensert Functional Equivalent Case Study

We had a customer who was bidding on a job for subassembly for a Defense Department manufacturer. Their bill of materials called for a floating insert in A286 steel with an OEM part number: KNKDL428JT.

This part is an Alcoa part that would not have been delivered for over 29 weeks – that’s more than half of a year! Not only would these parts take way too long, but they were also very expensive.

Functional Equivalents for Keenserts

So, this customer came to us for a solution. We were able to take their print, cross-reference their BOM, and find the functional equivalents they needed.

  • Note: Supplying us with your print is extremely important so that we can determine the internal and external threats, the material in all of the specifications for this key locking insert.

We went to our manufacturer, who was able to provide this part in five weeks with full certifications and a certificate of conformance certifying that it was a functional equivalent to the KNK part.

Why Choose MF Supply for Functional Equivalents?

By providing the functional equivalent, we were able to shorten the delivery time from 29 weeks down to five weeks. We obtained a cost savings of 59%. Our customer won the job. Their work was completed on time. The job was more profitable due to the cost savings. The manufacturer was able to pass those savings on to the end-user, and the job has been a repeater, and it’s been profitable for everyone involved.

If you find yourself in this situation and you’d like to evaluate if a functional equivalent is available for your application, or if you’d like to explore if you can save time and money while maintaining quality by using functional equivalence, our team is here for you!
