Value Collection 831009PR M3 Cone Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 831009PR is an M3 x 0.50 x 4 mm cone point set screw manufactured from alloy steel at Grade 14.9 (45H) for high-strength clamping applications. It features a hex drive with a 1.50 mm hex key size and a black oxide finish that provides moderate corrosion resistance. Conforming to DIN 914 and ISO 4027 standards, this set screw is engineered for precise, repeatable seating against a shaft or mating surface. Machinists, maintenance technicians, and assembly professionals install these fasteners when a positive, biting hold on a shaft or bore surface is required.

The cone point geometry concentrates clamping force at a single contact point, making this set screw well-suited for light-duty shaft locking, positioning, and indexing applications in mechanical assemblies. It is commonly used in machine tool components, motor shaft collars, gears, pulleys, and precision fixtures where metric fasteners are specified. The M3 thread size and 4 mm overall length target compact assemblies with limited engagement depth.

Key Features

• Cone point geometry provides a biting, positive hold on shaft surfaces
• Alloy steel Grade 14.9 (45H) construction delivers high tensile and torsional strength
• Black oxide finish adds mild corrosion resistance and reduces light reflection
• Hex socket drive accepts a 1.50 mm hex key for precise torque application in tight spaces
• Conforms to DIN 914 and ISO 4027 dimensional standards for interchangeability
• Metric thread M3 x 0.50 pitch suits compact precision assemblies

Compatibility

Designed as a metric-standard cone point set screw for use in any assembly specifying an M3 x 0.50 x 4 mm DIN 914 or ISO 4027 fastener. Verify thread engagement depth and shaft hardness before installation.

Installation Notes

Installation requires a 1.50 mm hex key; use a calibrated torque driver where assembly specifications demand controlled clamp load. De-energize and lock out all rotating machinery before servicing shaft fasteners. Inspect the mating shaft for adequate hardness so the cone point seats properly without damaging soft shaft surfaces. Follow applicable machine safety standards and manufacturer assembly guidelines during installation.
