Its smooth curves present lower stress risers than any other shape. The profile is actually a modified epicycloid, that is, the radius of curvature is constantly and continuously changing around the entire profile. The result is that the contact between the mail and female is not LINE contact (as in a square drive socket wrench), but conformal AREA contact. The contact patch is wider. This distributes the torque over a larger area, thus lowering the stress. Request A Quote The polygon profile is the greatest torque transmission shape ever devised... The result is that more torque can be transmitted in any given shaft diameter than with any other type of connection: splines, keys, interference fits, roller pins, square drives, hex shapes, and ANY other shape. The familiar square drive used in socket wrenches provides a useful comparison. When the square drive transmits torque, the theoretical contact is line contact at the four (4) corners. This is theoretical because in actuality, the male and female deform slightly to form a contact patch that has a width instead of pure line contact, which has no width. However, the width of the contact patch is small, but it depends on the characteristics of the materials involved.

This is a result of the fine level of workmanship we have received from Stoffel Polygon Systems. Thank you again for your teamwork on this project." Michael O'Hara from Strategic Sourcing Next Learn More What is a Polygon Kinematically ground polygonal shapes have been used as drive connections for more than 45 years. What is now referred to as Polygon Systems was developed by Fortunawerke, Stuttgart, West Germany, who patented a grinding machine capable of producing matched polygonal shaft and bore diameters.
