Value Collection A410471 Set Screw M3 X 0.50 Cup Point 316 Ss

Product Description

The VALUE COLLECTION A410471 is a metric cup point set screw designed for secure, low-profile fastening in mechanical assemblies. Manufactured from Grade 316 stainless steel to the Austenitic Grade A4 designation, this fastener resists corrosion in wet, chemical, and marine environments. The M3 x 0.50 thread pitch and 6 mm overall length make it well suited for small-bore applications requiring precise axial or rotational locking. Drive engagement is through a 1.5 mm hex key socket, conforming to DIN 916. Each package contains 25 pieces, allowing technicians to stock a working supply for repeat installations.

Cup point set screws are commonly installed in shaft collars, pulleys, gears, and mechanical couplings across HVAC equipment, pump assemblies, and general industrial machinery. The cup point geometry bites into the mating shaft to resist both axial and rotational movement without requiring a separate locking element. This fastener is appropriate for applications where a flush or recessed installation is required and where stainless steel corrosion resistance is necessary, such as in humid mechanical rooms or outdoor equipment enclosures.

Key Features

• Grade 316 stainless steel construction with Austenitic Grade A4 designation for superior corrosion resistance
• Cup point geometry provides positive shaft engagement and resists rotational and axial slippage
• M3 x 0.50 metric thread conforms to DIN 916 fastener standard
• 1.5 mm hex key drive for recessed, flush installation
• 6 mm overall length suits compact shaft collar and coupling applications
• Sold in a 25-piece package to support service stock requirements

Compatibility

Designed as a DIN 916 metric set screw for use in any M3 x 0.50 threaded bore requiring a cup point fastener. Suitable for shaft collars, mechanical couplings, and small-bore locking applications across industrial and HVAC equipment.

Installation Notes

Installation requires a 1.5 mm hex key or Allen driver. De-energize and lock out any machinery before adjusting or replacing set screws in rotating assemblies. Ensure the mating shaft and threaded bore are clean and free of debris before seating the fastener. Do not exceed the torque capacity appropriate for M3 stainless fasteners, and refer to equipment manufacturer documentation for specific torque requirements.
