Value Collection 833171PR M12 Dog Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 833171PR is an M12 x 1.75 x 16 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H). The dog point extension allows the screw to seat into a mating hole or groove on a shaft, providing positive location and preventing axial movement without marring the shaft surface. A black oxide finish adds moderate corrosion resistance and reduces light reflection. Drive is a 6 mm internal hex (Allen) socket. This fastener meets DIN 915 and ISO 4028 dimensional standards and is suited for mechanical assemblies, machine tools, and motion-control applications where precise shaft retention is required.

Dog point set screws of this size are commonly installed by machinists, millwrights, and maintenance technicians in shaft collars, shaft couplings, gearboxes, pulleys, and similar rotating or sliding components. The M12 x 1.75 metric thread and 16 mm overall length fit standard metric bores. Grade 14.9 (45H) alloy steel provides high proof load and torsional strength appropriate for heavy-duty clamping and locking applications in both industrial and OEM equipment contexts.

Key Features

• Dog point tip seats into shaft bore or groove for positive axial location
• Grade 14.9 (45H) alloy steel delivers high clamping and torsional strength
• Black oxide finish provides light corrosion protection and low reflectivity
• 6 mm hex socket drive for standard Allen key or hex bit installation
• Conforms to DIN 915 and ISO 4028 dimensional standards
• Metric thread M12 x 1.75 with 16 mm overall length

Compatibility

Designed as a standard metric dog point set screw per DIN 915 and ISO 4028, compatible with any M12 x 1.75 tapped hole requiring a dog point style retention fastener.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 6 mm hex key or Allen bit driver. Ensure the mating shaft or component has a properly sized dog point pocket or recess to accept the point before tightening. De-energize and lock out any connected machinery before servicing rotating assemblies. Do not exceed the rated proof load of the fastener; use a calibrated torque wrench appropriate for M12 metric fasteners when torque control is required by the assembly specification.
