ISO 4027 Set Screw (Cone Point)
ISO 4027 Cone Point Set Screws
DIN Equivalent: DIN 914 | Hex Socket Headless Screws
ISO 4027 cone point set screws feature a 120° tapered point that digs into the shaft material for maximum grip. The cone point is designed to seat into a pre-made dimple or create its own indentation, providing permanent locking action ideal for high-vibration applications.
Quick Specifications
Key Features
Self-Centering Action
Cone point naturally centers into a drilled dimple or recess. Provides precise, repeatable positioning every time.
Permanent Locking
Point penetrates shaft material creating a mechanical lock. Best choice for fixed positions that won't be adjusted.
120° Included Angle
Standard 120° angle matches common center drill angles. Use with pre-drilled dimples for maximum holding.
High Holding Power
Point penetration plus mechanical interlock provides excellent resistance to rotation and axial movement.

Installation Tips
💡 Best Practice
For maximum holding power, pre-drill a dimple in the shaft using a 120° center drill. The cone point will seat perfectly in the dimple, creating a mechanical interlock that resists both rotation and axial movement.
Without dimple: Cone point will create its own indentation, but holding power is reduced and shaft will be permanently marked.
