Value Collection 833125PS M8x1.25x50mm Dog Point Set Screw

Product Description

The VALUE COLLECTION 833125PS is an M8 x 1.25 x 50 mm dog point set screw manufactured from alloy steel to Grade 14.9 (45H). The dog point tip extends beyond the thread, providing a locating pin function that seats into a drilled hole or groove on a shaft to prevent axial and rotational movement. Finished in black oxide for moderate corrosion resistance, this screw is driven with a 4 mm hex key. It conforms to DIN 915 and ISO 4028 dimensional standards. Machinists, maintenance technicians, and mechanical assemblers install this fastener in applications requiring positive shaft retention under load.

This set screw is suited for metric mechanical assemblies where a dog point is specified for shaft-to-hub connections, gear hubs, pulleys, collars, and similar power transmission components. The Grade 14.9 (45H) material grade delivers high hardness and clamping force appropriate for demanding industrial and machinery applications. Overall length is measured at 50 mm, and thread pitch is 1.25 mm, consistent with standard M8 coarse thread specifications per ISO metric fastener standards.

Key Features

• Dog point tip provides positive shaft location and prevents axial displacement
• Grade 14.9 (45H) alloy steel for high hardness and clamping strength
• Black oxide finish for moderate corrosion resistance and reduced galling
• 4 mm hex key drive for precise torque application in confined spaces
• Conforms to DIN 915 and ISO 4028 dimensional standards
• M8 x 1.25 coarse metric thread, 50 mm overall length

Compatibility

Designed as a DIN 915 and ISO 4028 compliant metric set screw for use in M8 x 1.25 tapped holes in shaft collars, hubs, pulleys, and mechanical assemblies requiring a dog point retention method.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 4 mm hex key or hex bit driver. The mating component must have a properly drilled dog point recess or groove on the shaft to accept the point. De-energize and lock out all rotating equipment before installation or removal per applicable safety procedures. Do not exceed the rated material grade by substituting this fastener in applications specifying a different point type or thread class without engineering review.
