SOCKET SCREWS
ISO 4027 Truncated Cone Point Socket Set Screws
Headless socket set screws with truncated cone point for positioning and retention in mechanical assemblies.
Product Overview
The truncated cone point provides localized contact in a prepared seat or on a mating surface. It suits positioning arrangements that allow indentation and require a defined contact location. The point geometry and the seat must be considered together when specifying a retaining arrangement.
State the thread size, overall length, point detail and mating material in the enquiry. Hardness class, thread fit and the permitted setting torque must be selected for the application. Supplier confirmation is required for the requested material and size.

Size Range / Technical Notes
- Size Range
- Specify thread diameter, total length and point geometry. Exact size and material combinations require confirmation.
- Technical Notes
- Legacy DIN 914 corresponds to this product family; use the ordered ISO edition and verify dimensions instead of assuming universal interchangeability. Set screws are not intended for tensile loading. The 2026 title specifies a truncated cone point. Do not assume older DIN 914 cone-point geometry is unchanged. Confirm tip dimensions and the mating seat.
