Value Collection 533018PR M4 Cup Point Set Screw Din 916

Product Description

The VALUE COLLECTION 533018PR is an M4 x 0.70 x 4 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). The cup point geometry bites into the mating surface to resist rotation and axial movement, making it well suited for shaft-to-hub retention and collar positioning. Drive is a 2 mm internal hex (Allen key). The fastener conforms to DIN 916, ensuring dimensional consistency for metric applications. Machinists, millwrights, and maintenance technicians install this type of hardware during mechanical assembly and repair work across a wide range of equipment.

This set screw is used wherever a headless, flush-seating fastener is required in a metric threaded bore. Common applications include securing shaft collars, pulleys, sprockets, gears, and couplings in industrial machinery, HVAC equipment drives, pump assemblies, and general mechanical systems. The cup point is the standard choice when a permanent or semi-permanent bite into a softer shaft material is acceptable. Overall length of 4 mm suits shallow engagement requirements in compact components.

Key Features

• Cup point geometry provides positive grip into mating shaft surface
• Grade 14.9 (45H) alloy steel delivers high tensile and torsional strength
• 2 mm hex drive for standard Allen key or hex bit installation
• Conforms to DIN 916 for reliable metric dimensional compliance
• Headless design seats fully flush with or below the surface of the threaded component
• M4 x 0.70 thread with 4 mm overall length for compact, shallow-bore applications

Compatibility

Designed for use in any M4 x 0.70 metric threaded bore requiring a DIN 916 cup point set screw for shaft retention or positional locking.

Installation Notes

Installation is performed with a 2 mm hex key or matching hex bit driver. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Thread engagement should be clean and free of contamination before driving the screw to the required seating depth. Avoid applying excessive torque beyond the fastener rating, as over-tightening a high-grade set screw into a softer shaft can cause unintended deformation.
