DIN916 Cup point Hexagon Socket Set Screws
DIN 916 Hexagon Socket Set Screws feature a cup point designed to provide secure contact with the mating component while the screw is tightened inside a threaded hole. The recessed point allows the screw to grip the surface without requiring a sharp cone or projecting tip, making it suitable for positioning and securing components where a controlled clamping contact is preferred. The internal hexagon drive allows the screw to be installed in compact or recessed locations where access for a conventional wrench is limited. DIN 916 set screws can be used to secure shafts, collars, knobs, gears, guides, and other components against movement within threaded holes.
We supply DIN 916 set screws in carbon steel, alloy steel, and stainless steel, with different strength grades and surface finishes available according to the application. Stainless steel versions can be selected for corrosion-resistant environments, while hardened steel versions are suitable where higher clamping and wear resistance are required. Compared with other DIN set screw point styles, the cup point provides a different balance between holding force, surface contact, and potential marking of the mating component. The appropriate point design should therefore be selected according to whether the priority is secure positioning, surface protection, or resistance to movement.

Dimension Chart of DIN916 Cup Point Set Screws:
The dimension chart covers the main measurements of DIN 916 set screws, including thread size, overall length, cup point geometry, and internal hexagon dimensions. The screw length should be selected according to the available threaded hole depth and the required engagement with the mating component. When choosing a DIN 916 set screw, the hexagon socket size and cup point position should also be considered to ensure adequate tool access and consistent clamping. Custom dimensions can be produced according to drawings when a standard size does not meet the assembly requirements.

Mechanical Property:
ISO 898-5 — Alloy Steel Cup Point Set Screws
DIN 916 cup point set screws made from carbon steel or alloy steel can be specified according to ISO 898-5. This standard defines the mechanical and physical property requirements for set screws based on hardness classes. It covers metric coarse threads from M1.6 to M30 and fine threads from M8 × 1 to M30 × 2.
ISO 3506-3 — Stainless Steel Cup Point Set Screws
For applications requiring corrosion resistance, DIN 916 cup point set screws are also available in stainless steel grades covered by ISO 3506-3. This standard specifies the mechanical and physical properties of set screws made from corrosion-resistant stainless steel, including austenitic and duplex grades.
