Shakeproof™ Thread and MAThread® for Machine Motor


ITW’s customer was using a screw with an adhesive patch to secure their top load washer motor, but the fastener was costly and they were looking for alternatives.

In addition, the customer experienced cross threading issues with the bolt.


ITW’s Shakeproof™ thread was used as an alternative to the adhesive patch.

To address the cross threading issue, a MAThread® was added to the part.


By eliminating the adhesive patch and going to the Shakeproof™ Thread, our customer was able to save $200,000 annually while retaining the locking ability of the fastener. The addition of the MAThread® eliminated cross threading during assembly and the costly down time associate with it.
