Value Collection 833116PR M8x1.25x30mm Dog Point Set Screw

Product Description

The VALUE COLLECTION 833116PR is an M8 x 1.25 x 30 mm dog point set screw manufactured from alloy steel at Grade 14.9 (45H). It features a black oxide finish and a 4 mm hex drive, conforming to DIN 915 and ISO 4028 standards. The dog point tip extends beyond the end of the screw body, allowing it to locate into a mating hole or slot to prevent rotational and axial movement of a shaft or collar. This fastener is installed by maintenance technicians, millwrights, and mechanical assemblers working on precision positioning applications where a hardened, high-strength set screw is required.

This set screw is suited for use in industrial machinery, shaft collars, gear hubs, couplings, and mechanical assemblies where a protruding dog point is needed for positive component location. The metric M8 x 1.25 thread pitch and 30 mm overall length make it appropriate for medium-duty clamping and positioning tasks in both OEM manufacturing and field maintenance environments. The black oxide finish provides mild corrosion resistance and reduces light reflection in close-tolerance assemblies.

Key Features

• Dog point tip provides positive shaft location in mating holes or detents
• Grade 14.9 (45H) alloy steel construction delivers high clamping force and hardness
• Black oxide finish offers mild corrosion resistance and a low-reflectance surface
• 4 mm hex drive for precise torque application with standard hex keys
• Conforms to DIN 915 and ISO 4028 dimensional standards for consistent fitment
• Metric M8 x 1.25 thread with 30 mm overall length suits a wide range of shaft collar and hub applications

Compatibility

Designed as a DIN 915 and ISO 4028 compliant metric set screw for use in any M8 x 1.25 threaded bore requiring a dog point style fastener.

Installation Notes

Installation requires a 4 mm hex key or hex bit driver. Before installation, ensure the mating bore and dog point hole or detent are clean and free of debris. Always de-energize or lock out machinery before adjusting set screws on rotating components in accordance with applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of the fastener grade; refer to a standard metric fastener torque table for Grade 14.9 values appropriate to the application.
