Value Collection 533003PR Set Screw M3x0.50 Cup Point

Product Description

The VALUE COLLECTION 533003PR is an M3 x 0.50 x 5 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). Set screws are headless fasteners that thread fully into a tapped hole and apply clamping or locking force directly against a shaft, hub, or mating surface. The cup point geometry creates a small indentation in the mating surface for positive retention and resistance to vibration loosening. Driven with a 1.50 mm hex key, this fastener conforms to DIN 916 and is sized in metric units. It is used across mechanical assemblies, motor shafts, collars, pulleys, and precision equipment wherever a flush or recessed fastener is required.

This set screw is suited for residential and commercial mechanical applications including HVAC equipment assemblies, motor shaft collars, fan hubs, and general industrial machinery. The M3 x 0.50 thread pitch and 5 mm overall length fit standard metric tapped holes in light-duty to medium-duty assemblies. Technicians and millwrights working on rotating equipment or component alignment will find this fastener appropriate for precision shaft-locking tasks. The minimum order quantity is 100 pieces per order.

Key Features

• M3 x 0.50 metric thread conforms to DIN 916 standard
• Cup point tip creates a locking indentation in the mating surface for vibration resistance
• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• 1.50 mm hex key drive for precise torque application in tight spaces
• Headless design allows flush or below-surface installation
• 5 mm overall length suits standard light-duty to medium-duty shaft-locking applications

Compatibility

Designed as a DIN 916 metric set screw for use in any M3 x 0.50 tapped hole requiring a cup point headless fastener in mechanical, HVAC, or industrial assembly applications.

Installation Notes

Installation is performed by threading the set screw into a pre-tapped M3 x 0.50 metric hole using a 1.50 mm hex key. De-energize and lock out any rotating equipment or electrical systems before installing or removing set screws on shaft-mounted components. Do not exceed the torque capacity of the M3 thread to avoid stripping the tapped hole or shearing the fastener. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener preload requirements.
