Value Collection 833041PR M4 Dog Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 833041PR is an M4 x 0.70 x 20 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H) and finished in black oxide. The dog point extension at the tip locates into a mating hole or recess on a shaft, providing positive rotational and axial retention without marring the shaft surface. Drive is via a 2 mm hex key socket. This fastener conforms to DIN 915 and ISO 4028 dimensional standards and is suited for mechanical assemblies where precise positioning and repeatable torque loading are required. Machinists, maintenance technicians, and mechanical assemblers are the typical installers.

This set screw is used in industrial and light commercial mechanical assemblies, tooling fixtures, shaft collars, gear hubs, and rotating component retention applications. The metric M4 x 0.70 thread pitch and 20 mm overall length suit compact assemblies where space is limited. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for precision instrument and machine tool applications where uncoated steel would be unsuitable.

Key Features

• Dog point tip for positive shaft location and axial retention without shaft damage
• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• 2 mm hex key drive for access in confined spaces
• Conforms to DIN 915 and ISO 4028 dimensional standards for interchangeability
• M4 x 0.70 metric thread for use in standard metric tapped holes

Compatibility

Designed as a direct-fit replacement or standard metric fastener for any assembly requiring an M4 x 0.70 x 20 mm dog point set screw conforming to DIN 915 or ISO 4028 specifications.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a 2 mm hex key. Ensure the mating tapped hole is clean, properly formed to M4 x 0.70 tolerance, and the shaft recess or locating hole is aligned before seating the dog point. Apply appropriate thread-locking compound if vibration loosening is a concern in the application. De-energize and lock out any powered equipment before servicing assemblies containing set screws.
