Value Collection 833058PR M5 Dog Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 833058PR is an M5 x 0.80 x 25 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H) - one of the highest strength grades available for metric set screws. The dog point tip extends beyond the screw body to locate into a mating hole or groove, preventing shaft rotation or axial movement without marring the shaft surface. A black oxide finish provides moderate corrosion resistance and reduces galling during installation. Drive is a 2.50 mm hex key socket, conforming to DIN 915 and ISO 4028 dimensional standards. Maintenance technicians, millwrights, and mechanical assemblers install this fastener in precision shaft-to-hub applications.

This set screw is suited for light industrial, machine tool, and general mechanical assembly applications where positive shaft location is required. The dog point engages a drilled detent or flat on the shaft, providing axial retention and rotational indexing. Its metric M5 x 0.80 thread pitch and 25 mm overall length fit standard M5 threaded holes in collars, couplings, pulleys, and similar components. Minimum order quantity is 10 pieces; package quantity ships as 1 unit.

Key Features

• Dog point tip for positive shaft location in drilled detents or flats
• Grade 14.9 (45H) alloy steel for high clamping force and tensile strength
• Black oxide finish for mild corrosion resistance and reduced galling
• 2.50 mm hex key drive for precise torque application in tight clearances
• Conforms to DIN 915 and ISO 4028 dimensional standards
• M5 x 0.80 thread, 25 mm overall length - fully metric dimensioned

Compatibility

Designed for use in standard M5 x 0.80 threaded collars, shaft couplings, pulleys, and hubs where a dog point set screw per DIN 915 or ISO 4028 is specified.

Installation Notes

Millwrights and mechanical assemblers should de-energize and lock out all rotating equipment before installing or adjusting set screws. Use a calibrated 2.50 mm hex key and follow the torque specification listed in the equipment manufacturer's service documentation for Grade 14.9 fasteners at M5 diameter. Ensure the mating shaft detent or flat is clean and free of burrs before engaging the dog point. Do not substitute a lower-grade set screw in applications where Grade 14.9 is specified.
