Value Collection 831020PR M4 Cone Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 831020PR is an M4 x 0.70 x 8 mm cone point set screw designed for secure, positive locking against shafts and mating components. Manufactured from Grade 14.9 (45H) alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in a compact metric form factor. Driven by a 2 mm hex key, it conforms to DIN 914 and ISO 4027 dimensional standards. Machinists, assembly technicians, and maintenance professionals install this type of set screw where a penetrating point is needed to bite into a shaft surface and resist rotational or axial movement under load.

Cone point set screws are commonly used in precision mechanical assemblies, motion control components, shaft collars, pulleys, gears, and couplings where permanent or semi-permanent axial locking is required. The cone point geometry concentrates clamping force at a single contact area, making it well suited for softer shaft materials or applications where the point is intended to seat into a drilled indent on the shaft. This part is appropriate for light industrial, manufacturing, and maintenance applications requiring a metric M4 fastener to DIN 914 or ISO 4027 specification.

Key Features

• Cone point geometry for positive shaft penetration and axial retention
• Grade 14.9 (45H) alloy steel construction for high-strength performance
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to DIN 914 and ISO 4027 fastener standards
• 2 mm hex drive for precise torque application in tight spaces
• Metric thread M4 x 0.70 pitch for compatibility with metric assemblies

Compatibility

Designed as a standard DIN 914 and ISO 4027 compliant M4 x 0.70 x 8 mm cone point set screw suitable for use in any metric-threaded application requiring a Grade 14.9 alloy steel fastener of this size.

Installation Notes

Installation is performed with a 2 mm hex key; use a calibrated torque tool where precise clamping force is required. Always de-energize and lock out any machinery before servicing fasteners on rotating components. Cone point set screws can deform softer shaft materials upon tightening — verify shaft material compatibility before installation. Minimum order quantity is 100 pieces; package quantity is 1.
