Value Collection 833112PR M8 Set Screw Dog Point Alloy Steel

Product Description

The VALUE COLLECTION 833112PR is an M8 x 1.25 x 20 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a hex drive, black oxide finish, and conforms to DIN 915 and ISO 4028 standards. The dog point tip extends beyond the thread to locate or retain mating components with precision, making this fastener well suited for mechanical assemblies, shaft collars, and positioning applications. A 4 mm hex key is required for installation. Machinists, millwrights, and mechanical assembly technicians are the typical installers. Minimum order quantity is 100 pieces.

This set screw is used in industrial and mechanical applications where a protruding dog point is required to engage a mating hole or recess in a shaft or housing. The M8 thread and 20 mm overall length make it a common choice for shaft collar retention, gear hub locking, and precision positioning in light to medium-duty machinery. The Grade 14.9 (45H) alloy steel construction provides high tensile strength for demanding mechanical fastening tasks.

Key Features

• Dog point tip for positive shaft or bore engagement and precise component location
• Grade 14.9 (45H) alloy steel for high tensile and torsional strength
• Black oxide finish provides mild corrosion resistance and reduces galling during installation
• Hex drive (4 mm hex key) for controlled torque application in confined spaces
• Conforms to DIN 915 and ISO 4028 for standardized dimensional compliance
• Metric thread specification: M8 x 1.25, 20 mm overall length

Compatibility

Designed as a DIN 915 and ISO 4028 compliant dog point set screw for use in any M8 x 1.25 threaded bore requiring a projecting dog point for shaft or component retention.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians. Ensure the mating threaded hole is clean and free of debris before threading. Use a calibrated 4 mm hex key or T-handle driver to apply consistent torque. Power down and de-energize any rotating equipment before servicing fasteners on shafts or hubs.
