Value Collection 831114PR M8 Cone Point Set Screw 25mm

Product Description

The VALUE COLLECTION 831114PR is an M8 x 1.25 x 25 mm cone point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a hex socket drive requiring a 4 mm hex key and a black oxide finish that provides mild corrosion resistance. This fastener is designed for high-stress clamping and locking applications where the cone point bites into a mating surface or seats into a matching recess to prevent rotational or axial movement. It is commonly installed by machinists, millwrights, and maintenance technicians in industrial and commercial settings.

This set screw is suited for use in shaft-collar assemblies, pulleys, gears, and similar mechanical components where a permanent or semi-permanent holding force is required. The cone point geometry concentrates clamping load at a single contact area, making it appropriate for hardened shafts and precision bores. Overall length is measured as the full 25 mm body length. This fastener conforms to DIN 914 and ISO 4027 dimensional standards, making it compatible with metric hardware systems.

Key Features

• Grade 14.9 (45H) alloy steel construction delivers high tensile and torsional strength
• Cone point geometry concentrates clamping force for secure shaft and bore retention
• 4 mm hex socket drive for use with standard metric hex keys
• Black oxide finish provides mild corrosion and wear resistance
• Conforms to DIN 914 and ISO 4027 dimensional standards
• Metric thread designation M8 x 1.25 with 25 mm overall length

Compatibility

Designed as an OEM-style replacement or standard-service fastener for metric mechanical assemblies requiring a Grade 14.9 cone point set screw with M8 x 1.25 threading and 25 mm overall length per DIN 914 and ISO 4027 specifications.

Installation Notes

Installation is typically performed by a machinist or millwright using a 4 mm hex key or hex bit driver. Ensure the mating shaft or bore is clean and free of debris before seating the cone point. De-energize or lock out any rotating equipment before installing or removing set screws per applicable OSHA lockout/tagout procedures. Do not exceed the torque range appropriate for the fastener grade and thread size as specified in applicable fastener standards.
