DIN 915 Socket Set Screws, Dog Point
We supply DIN 915 dog point socket set screws in self colour high-strength steel, property class 45H (commonly called grade 14.9), and A2/A4 stainless steel, from M2 to M24. The parallel dog point locates into a drilled hole, keyway or slot, transmitting drive and fixing position without marking the shaft around it.

Is DIN 915 the same as ISO 4028?
DIN 915 and ISO 4028 both cover dog point hexagon socket set screws. The standards are closely related, although dimensional or technical differences may exist. If your drawing specifies either designation, send us the requirement and we can identify the appropriate product.
What is a dog point set screw used for?
The parallel pin-like point engages a hole, keyway or slot in the mating part, so the screw locates and drives rather than gripping by friction - common in shaft couplings and adjustable mechanisms.
Is DIN 915 available in stainless steel?
Yes - DIN 915 dog point set screws are available in A2 and A4 stainless steel across a wide range of metric sizes, alongside high-strength steel, property class 45H (commonly called grade 14.9), self colour.
