What is the difference between DIN 915 and DIN 916 set screws?

In summary, DIN 915 and DIN 916 set screws are types of fasteners used to secure objects together in mechanical and industrial applications. They have different designs and shapes, with DIN 915 having a pointed tip and flat head, and DIN 916 having a cup-shaped tip and socket or Allen head. These set screws are not interchangeable, as using the wrong type could result in an insecure connection or damage. The type of set screw to use depends on the specific needs of the application, with DIN 915 being better for flush surfaces and DIN 916 for more secure and tamper-proof connections. In addition to their design, DIN 916 set screws are typically made of stronger materials and have a higher tensile strength compared to DIN

Welcome to PF.
The dog point DIN 915 is designed to enter a prepared hole or slot in the shaft.
The cup point DIN 916 is designed to cut a circular dent and so lock to the shaft.
