Value Collection 533108P M8 X 1.25 X 12 Mm Cup Point Set Screw

Product Description

The VALUE COLLECTION 533108P is an M8 x 1.25 metric cup point set screw manufactured from alloy steel to Grade 14.9 (45H). At 12 mm overall length, it seats with a 4 mm hex key drive and conforms to DIN 916 dimensional standards. The cup point geometry creates a small indentation in the mating surface, providing strong resistance to rotation and axial movement without full penetration of the workpiece. This fastener is used in mechanical assemblies where a secure, low-profile hold is required on shafts, collars, and similar components. Installation is performed by machinists, maintenance technicians, and mechanical assemblers.

This set screw is suited for use in machine tool fixtures, shaft collars, pulleys, gears, and general mechanical assemblies requiring a metric M8 x 1.25 thread. The DIN 916 standard ensures dimensional consistency with metric hardware across industrial and commercial equipment applications. The cup point style is appropriate where minor surface marking of the mating shaft is acceptable and a more positive grip than a flat or oval point provides is needed.

Key Features

• M8 x 1.25 metric thread with 12 mm overall length
• Cup point geometry for positive grip and rotation resistance on shaft surfaces
• Alloy steel construction rated to Grade 14.9 (45H) for high tensile strength
• 4 mm hex key (Allen) drive for installation in confined spaces
• Conforms to DIN 916 fastener standard for dimensional interchangeability

Compatibility

Designed for use in metric M8 x 1.25 threaded applications requiring a DIN 916 cup point set screw. Suitable for shaft collars, pulleys, gears, and mechanical fixtures using standard metric hardware.

Installation Notes

Install using a 4 mm hex key torqued to the assembly specification for Grade 14.9 alloy steel fasteners. De-energize and lock out all rotating or powered equipment before servicing any component secured by this set screw. Ensure threads are clean and free of debris before installation to avoid cross-threading. Do not substitute an undersized hex key, as this risks rounding the drive socket.
