Value Collection 833108PR M8 X 1.25 X 12mm Dog Point Set Screw

Product Description

The VALUE COLLECTION 833108PR is an M8 x 1.25 metric set screw with a dog point tip, manufactured from alloy steel at material grade 14.9 (45H). It measures 12 mm in overall length and features a 4 mm hex drive for installation with a standard hex key. The black oxide finish provides a baseline level of corrosion resistance and reduces light reflection. This fastener conforms to DIN 915 and ISO 4028 dimensional standards. It is used in mechanical assemblies where a protruding dog point is needed to locate a mating part, prevent rotational slippage, or index a shaft. Maintenance technicians and machine assemblers are the typical installers.

The 833108PR is suited for industrial and mechanical applications requiring a headless, flush-mount fastener with positive shaft engagement. The dog point extends beyond the screw tip, seating into a matching hole or recess in the shaft or mating component to resist rotational and axial movement. Common use cases include shaft collars, set screw hubs, pulleys, gears, and fixture tooling. This is a metric fastener intended for use in metric-threaded bores conforming to M8 x 1.25 thread form.

Key Features

• Dog point tip provides positive location in mating shaft holes to resist rotational slippage
• Alloy steel construction at grade 14.9 (45H) for high tensile and torsional strength
• 4 mm hex drive for installation with a standard hex key or Allen wrench
• Black oxide finish reduces light reflection and offers mild corrosion resistance
• Conforms to DIN 915 and ISO 4028 dimensional standards for drop-in replacement compatibility
• M8 x 1.25 thread form with 12 mm overall length suits compact mechanical assemblies

Compatibility

Designed as a DIN 915 and ISO 4028 conforming set screw for any M8 x 1.25 threaded bore requiring a dog point fastener. Minimum order quantity is 100 pieces per order.

Installation Notes

Installation requires a 4 mm hex key; confirm the drive is fully seated before applying torque to avoid rounding the socket. Ensure the mating shaft contains a properly sized dog point recess or locating hole before tightening. De-energize and lock out any rotating machinery before servicing or replacing set screws in live equipment. Follow applicable machinery safety standards and the equipment manufacturer's fastener specifications for proper seating depth and loading.
