Value Collection 831024PR M4 Cone Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 831024PR is an M4 x 0.70 x 20 mm cone point set screw manufactured from Grade 14.9 (45H) alloy steel with a black oxide finish. Set screws are headless fasteners threaded along their full length, used to secure a component - such as a collar, pulley, or gear - against or into a mating surface. The cone point tip concentrates clamping force at a single location, creating a strong bite into the mating part. This screw conforms to DIN 914 and ISO 4027 standards and is driven with a 2 mm hex key. It is a metric fastener suited for mechanical assemblies, maintenance, and fabrication work across industrial and trade environments.

This set screw is appropriate for applications requiring a positive, vibration-resistant lock between a shaft and hub or between two mated components. The cone point style is commonly selected when a semi-permanent or permanent installation is acceptable, as the point indent into the shaft provides strong resistance to axial and rotational movement. Typical install scenarios include machine component assembly, motor shaft collars, and general industrial maintenance work. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity. This fastener uses metric threading and tooling, making it well suited for equipment with metric fastener standards.

Key Features

• M4 x 0.70 metric thread with 20 mm overall length for precise fitment in metric assemblies
• Cone point geometry concentrates clamping load for strong shaft engagement and resistance to rotation
• Grade 14.9 (45H) alloy steel construction provides high tensile and torsional strength
• Black oxide finish offers mild corrosion resistance and a low-reflectance surface
• Conforms to DIN 914 and ISO 4027 fastener standards
• Driven with a 2 mm hex key for installation in confined spaces

Compatibility

Designed as a standard metric set screw for use in any mechanical assembly specifying an M4 x 0.70 x 20 mm cone point set screw per DIN 914 or ISO 4027.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 2 mm hex key. Ensure the mating shaft or surface is clean and free of debris before seating the cone point, as the point will indent the shaft material upon tightening. Do not exceed the torque capacity of the M4 thread to avoid stripping. Note that cone point set screws can cause permanent marking on shaft surfaces, so verify this style is acceptable for the application before installation.
