SUMMARY

The discussion clarifies the differences between DIN 915 and DIN 916 hexagon socket set screws. The DIN 915 set screw features a dog point designed to fit into a prepared hole or slot in the shaft, making it suitable for applications requiring precise alignment. In contrast, the DIN 916 set screw has a cup point that cuts a circular dent into the shaft, providing a locking mechanism. This distinction is crucial for selecting the appropriate set screw for specific mechanical applications.

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.
