Value Collection 833124PR M8 X 1.25 X 40mm Dog Point Set Screw

Product Description

The VALUE COLLECTION 833124PR is an M8 x 1.25 x 40 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a 4 mm hex drive socket and a black oxide finish. The dog point extends beyond the thread to locate into a mating hole or slot, providing positive positioning and resistance to lateral movement. This fastener meets DIN 915 and ISO 4028 standards. Machinists, toolmakers, and maintenance technicians install this type of set screw in collars, hubs, pulleys, and shaft assemblies where a protruding point is required for precise component alignment.

This set screw is suited for industrial and mechanical applications where metric fasteners are specified. Typical installations include machine tool assemblies, power transmission components, and fixture work where a dog point is required to engage a corresponding recess or flat on a shaft. The black oxide finish provides a mild level of corrosion resistance while reducing light reflection in precision environments. This fastener is sold individually with a minimum order quantity of 5 units.

Key Features

• Dog point geometry for positive shaft location and lateral load resistance
• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• 4 mm hex drive for standard hex key installation
• Black oxide finish for mild corrosion resistance and reduced glare
• Meets DIN 915 and ISO 4028 dimensional standards
• Metric thread: M8 x 1.25, overall length 40 mm

Compatibility

Designed as a metric set screw conforming to DIN 915 and ISO 4028, suitable for use in collars, hubs, and shaft assemblies specifying an M8 x 1.25 dog point set screw.

Installation Notes

Installation requires a 4 mm hex key or hex bit driver. Ensure the mating shaft recess or flat is properly sized to accept the dog point before torquing. De-energize and lock out any rotating machinery before installing or removing set screws in shaft assemblies. Refer to applicable machine or equipment torque specifications and follow standard mechanical assembly practices.
