Value Collection 831080PR Set Screw M6x1 20mm Cone Point

Product Description

The VALUE COLLECTION 831080PR is a metric set screw designed for mechanical assemblies requiring a secure, low-profile fastener with no protruding head. This cone point set screw threads into a tapped hole and bites into a mating shaft or surface to resist rotation and axial movement. It is manufactured from alloy steel to Grade 14.9 (45H) and carries a black oxide finish that provides moderate corrosion resistance and reduces light reflection. The hex socket drive accepts a 3 mm hex key for installation. Machinists, millwrights, and maintenance technicians install this fastener in motors, pulleys, couplings, collars, and similar mechanical components.

This set screw is suited for both light industrial and precision mechanical applications where shaft locking or position fixing is required. The M6 x 1.00 thread pitch and 20 mm overall length make it a common choice for mid-size shaft collars, sprockets, and gear hubs across production machinery, conveyor systems, and general fabrication work. It conforms to DIN 914 and ISO 4027 standards, making it interchangeable with metric fasteners specified to those standards in engineering drawings and OEM documentation.

Key Features

• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• Cone point geometry concentrates clamping force for a positive bite into the shaft surface
• Black oxide finish provides mild corrosion resistance and a non-reflective appearance
• 3 mm hex socket drive compatible with standard hex keys and hex-bit drivers
• Conforms to DIN 914 and ISO 4027 dimensional standards
• Metric thread M6 x 1.00 with 20 mm overall length for consistent dimensional fit

Compatibility

Designed as a DIN 914 and ISO 4027 compliant metric set screw suitable for use in any application specifying an M6 x 1.00 x 20 mm cone point set screw with hex socket drive.

Installation Notes

Installation is performed with a 3 mm hex key or equivalent hex-bit driver; ensure the tool is fully seated before applying torque to avoid rounding the socket. Clean and degrease the tapped hole and shaft contact surface before installation to ensure proper seating of the cone point. De-energize and lock out any machinery before servicing fasteners on rotating components per applicable OSHA lockout/tagout procedures. Avoid reusing set screws that show deformation at the cone point, as this reduces holding force.
