Value Collection 831048PR M5 X 0.80 X 8 Mm Cone Point Set Screw

Product Description

The VALUE COLLECTION 831048PR is an M5 x 0.80 x 8 mm cone point set screw designed for secure, permanent fastening applications where a locking hold is required against a shaft or mating surface. Manufactured from alloy steel to Grade 14.9 (45H), this set screw delivers high tensile and torsional strength suited to demanding industrial and mechanical assembly work. A black oxide finish provides a base level of corrosion resistance and reduces surface reflectivity. The hex drive socket accepts a 2.50 mm hex key for installation and removal. This fastener conforms to DIN 914 and ISO 4027 dimensional standards.

Cone point set screws are commonly used in shaft collars, shaft couplings, gears, pulleys, and similar rotating or fixed assemblies where the point is intended to indent or seat into the mating material for a positive, non-slip hold. This fastener is appropriate for light machinery, tool-and-die, automation equipment, and general mechanical assembly work performed by machinists, maintenance technicians, and mechanical assemblers. The M5 x 0.80 metric thread pitch is a standard size found across a broad range of metric mechanical components.

Key Features

• Cone point geometry seats into mating material for a positive, non-slip hold on shafts and hubs
• Grade 14.9 (45H) alloy steel construction provides high tensile and torsional strength
• Black oxide finish offers mild corrosion resistance and low surface reflectivity
• 2.50 mm hex drive socket for standard hex key installation
• Conforms to DIN 914 and ISO 4027 dimensional standards
• Metric M5 x 0.80 thread size for compatibility with standard metric assemblies

Compatibility

Designed as a standard metric set screw for use in any M5 x 0.80 threaded bore application requiring a cone point fastener per DIN 914 or ISO 4027 specifications.

Installation Notes

Installation is performed with a 2.50 mm hex key. Ensure the threaded bore is clean and free of debris before threading the set screw in by hand to avoid cross-threading. Apply appropriate thread-locking compound if vibration resistance is required. Follow applicable machine safety lockout and tagout procedures before servicing any assembly containing set screws.
