Value Collection 533104P Set Screw M8x1.25x8mm Cup Point

Product Description

The VALUE COLLECTION 533104P is an M8 x 1.25 x 8 mm cup point set screw designed for secure, non-projecting fastening in mechanical assemblies. Manufactured from alloy steel to Grade 14.9 (45H), this set screw delivers high tensile and torsional strength for demanding industrial and commercial applications. It is driven by a 4 mm hex key and conforms to DIN 916 dimensional standards. The cup point geometry bites into the mating shaft surface to resist axial and rotational movement without requiring a projecting head. Machinists, millwrights, and maintenance technicians commonly install this fastener when assembling gears, collars, pulleys, and similar shaft-mounted components.

This set screw is suited for use in rotating equipment, power transmission assemblies, and precision mechanical fixtures where a flush or recessed fastener is required. The metric M8 x 1.25 thread pitch and 8 mm overall length make it appropriate for mid-size shaft collar and hub applications across general manufacturing, industrial maintenance, and OEM equipment assembly environments. It ships in a minimum order quantity of 100 pieces, making it appropriate for production and MRO restocking purchases.

Key Features

• M8 x 1.25 metric thread with 8 mm overall length for precise fitment in standard M8 tapped holes
• Cup point geometry grips shaft surface to prevent axial and rotational slip
• Grade 14.9 (45H) alloy steel construction provides high clamp load and torsional strength
• 4 mm hex drive for standard hex key or Allen wrench installation
• Conforms to DIN 916 fastener standard for dimensional consistency
• No projecting head — fully recessed installation for safety in rotating assemblies

Compatibility

Designed as a standard DIN 916 metric set screw for use in any M8 x 1.25 tapped hole requiring a cup point, headless configuration. Suitable for shaft collars, gears, pulleys, and mechanical hubs specifying a Grade 14.9 alloy steel fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 4 mm hex key. De-energize and lock out all equipment before servicing any shaft-mounted assembly. Ensure the tapped hole is clean and free of debris before threading the screw. Do not exceed the torque capacity of the fastener grade or the tapped material.
