Value Collection SS6X04016-050BX M4 Set Screw Din 916

Product Description

The VALUE COLLECTION SS6X04016-050BX is a metric cup point set screw designed for secure, recessed fastening applications in mechanical assemblies. It features an M4 x 0.70 thread profile with an overall length of 16 mm and a 2 mm hex key drive. Manufactured from 18-8 austenitic stainless steel (Grade A2), it offers solid corrosion resistance in moderate-exposure environments. This fastener conforms to DIN 916, a recognized international standard for hexagon socket set screws with cup point. It is installed by machine builders, millwrights, maintenance technicians, and other trade professionals requiring a reliable, non-protruding fastening solution.

Cup point set screws are commonly used to lock shafts, collars, pulleys, gears, and similar rotating or fixed components in place without a protruding head. The cup point configuration bites into the mating surface to resist rotation and axial movement. This fastener is suited for use in light to medium-duty assemblies where a flush or recessed profile is required, including HVAC blower assemblies, pump shaft collars, and general mechanical equipment maintenance in residential and commercial settings.

Key Features

• M4 x 0.70 metric thread with 16 mm overall length for compact, recessed installations
• Cup point geometry bites into mating surfaces to resist axial and rotational movement
• 18-8 austenitic stainless steel (Grade A2) construction resists rust and corrosion
• 2 mm hex key drive for standard Allen wrench installation in tight clearances
• Conforms to DIN 916 fastener standard for consistent dimensional accuracy
• Sold in a minimum order quantity of 50 pieces, suitable for shop stock or bulk repair use

Compatibility

Designed as a DIN 916 standard metric set screw for use in any M4 x 0.70 threaded bore requiring a cup point, recessed-drive fastener.

Installation Notes

Installation is performed with a 2 mm hex key (Allen wrench). Ensure the threaded bore is clean and free of debris before threading the screw in by hand to avoid cross-threading. Apply appropriate thread-locking compound if vibration resistance is required. Do not exceed the recommended seating torque for M4 stainless fasteners as specified by your assembly documentation, as over-torquing can gall or seize stainless threads.
