Value Collection 831026PR M4 Cone Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 831026PR is an M4 x 0.70 x 4 mm cone point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a hex drive socket sized at 2 mm and a black oxide finish for corrosion resistance in dry or lightly lubricated environments. Conforming to DIN 914 and ISO 4027 standards, this fastener is suited for applications where precise holding force against a shaft or mating surface is required. Machinists, maintenance technicians, and assembly professionals install these screws in mechanical assemblies where the cone point bites into the mating component to resist rotational or axial movement.

This set screw is used in mechanical and industrial applications including motor shaft collars, pulleys, gears, knobs, and coupling assemblies. The cone point geometry concentrates clamping force at a single contact location, making it well suited for permanent or semi-permanent installations into softer shaft materials. The metric M4 x 0.70 thread pitch and 4 mm overall length make it appropriate for compact or space-constrained assemblies common in light machinery, HVAC equipment, and industrial automation components.

Key Features

• Cone point geometry concentrates holding force for secure shaft engagement
• Alloy steel construction to Grade 14.9 (45H) for high tensile and torsional strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Hex drive socket accepts a 2 mm hex key for installation in tight clearances
• Conforms to DIN 914 and ISO 4027 dimensional standards for consistent fit
• Metric M4 x 0.70 thread for use in metric-threaded bores

Compatibility

Designed as a standard metric set screw for use in any M4 x 0.70 threaded bore requiring a cone point, DIN 914 or ISO 4027 compliant fastener.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 2 mm hex key. Ensure the threaded bore is clean and free of debris before driving the screw. Do not exceed the rated torque range for Grade 14.9 alloy steel set screws as specified by the equipment manufacturer. Apply thread-locking compound if vibration is a concern and the application permits it.
