Value Collection 833009PS M3 X 0.50 X 4 Mm Dog Point Set Screw

Product Description

The VALUE COLLECTION 833009PS is an M3 x 0.50 x 4 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H) and finished with a black oxide coating. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft by bearing down on it or seating into a mating recess. The dog point extends beyond the thread end, providing positive shaft location and resistance to lateral movement. The 1.50 mm hex drive accepts a standard metric hex key. This screw conforms to DIN 915 and ISO 4028 dimensional standards.

Dog point set screws in this size range are common in light mechanical assemblies, motion control components, instrumentation, and small-bore shaft collars. The M3 x 0.50 thread pitch is a standard metric coarse series, suitable for tapped holes in steel, aluminum, and similar materials. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. These fasteners are installed by maintenance technicians, machinists, and mechanical assemblers working on equipment where positive shaft registration is required.

Key Features

• Dog point tip for positive shaft location and resistance to axial movement
• Grade 14.9 (45H) alloy steel construction for high clamping force in a compact size
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• 1.50 mm hex drive for standard metric hex key installation
• Conforms to DIN 915 and ISO 4028 dimensional standards
• Metric M3 x 0.50 thread — standard coarse pitch for broad material compatibility

Compatibility

Designed for use in M3 x 0.50 tapped through-holes or blind holes conforming to DIN 915 and ISO 4028 specifications, typical in metric mechanical assemblies requiring dog point shaft retention.

Installation Notes

Installation is performed with a 1.50 mm metric hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any equipment before accessing shaft collars or rotating components. Thread engagement depth should be verified against the tapped hole depth to prevent bottoming or stripping. Minimum order quantity for this part is 100 pieces.
