Value Collection SS6X02512-050BX M2.5 Set Screw Din 916

Product Description

The VALUE COLLECTION SS6X02512-050BX is an M2.5 x 0.45 x 12 mm cup point set screw manufactured from 18-8 austenitic stainless steel, Grade A2. It is driven by a 1.30 mm hex key and conforms to DIN 916, the standard governing socket set screws with cup points. The cup point geometry bites into the mating shaft to resist rotation and axial movement without a protruding head. This fastener is suited for light assemblies, shafting, and precision components where a low-profile, corrosion-resistant locking fastener is required. Installation is performed by machinists, maintenance technicians, and assembly professionals working with metric hardware.

This set screw is used in applications requiring a fully recessed, headless fastener that sits flush or below the surface of the workpiece. Typical uses include securing collars, pulleys, gears, and knobs to shafts in mechanical assemblies. The stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact. The metric M2.5 x 0.45 thread and 12 mm overall length suit small-diameter shaft applications common in instrumentation, light machinery, and HVAC actuator assemblies.

Key Features

• M2.5 x 0.45 metric thread with 12 mm overall length for small-shaft applications
• Cup point geometry provides firm bite into shaft surface to resist rotation and axial movement
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in humid or mildly corrosive environments
• Internal hex drive requires a 1.30 mm hex key for installation and removal
• Conforms to DIN 916 fastener standard for consistent dimensional tolerances
• Sold in multiples of 50 units minimum order quantity

Compatibility

Designed as a standard DIN 916 metric cup point set screw suitable for use in any application accepting an M2.5 x 0.45 threaded headless socket set screw.

Installation Notes

Installation requires a 1.30 mm hex key; use of an incorrect key size can strip the socket and should be avoided. Thread the set screw in by hand to confirm proper thread engagement before applying torque. Ensure the shaft is clean and free of burrs before seating the cup point. No power or fluid shutoff is required for typical bench assembly applications, but follow the appropriate lockout procedures when servicing live machinery.
