Value Collection SS6X02504-050BX Set Screw M2.5 X 0.45 Cup

Product Description

The VALUE COLLECTION SS6X02504-050BX is a metric cup point set screw used to secure components onto shafts, collars, and hubs without a protruding head. Manufactured to DIN 916 standards from 18-8 austenitic stainless steel (Grade A2), it delivers solid corrosion resistance in wet, chemical-adjacent, or outdoor environments. The M2.5 x 0.45 thread pitch paired with a 4 mm overall length makes this a precise fastener for small-bore applications. Drive is a 1.30 mm hex key socket. This box contains 50 pieces, making it suitable for production runs, repair kits, or service truck stock. Installation requires a matching hex key driver and is performed by machinists, maintenance technicians, and trade professionals working with precision assemblies.

This set screw is appropriate for light-duty shaft-locking applications across HVAC equipment, plumbing valve assemblies, electrical enclosure hardware, and general mechanical assemblies where a flush or below-surface fastener is required. The cup point geometry bites into the mating shaft surface to resist rotational and axial movement. The metric M2.5 thread standard makes it compatible with metric-dimensioned components common in imported equipment and precision instruments. Sold in a box quantity of 50 pieces to support volume installation or service work.

Key Features

• DIN 916 standard cup point set screw for metric applications
• 18-8 stainless steel, austenitic Grade A2 for corrosion resistance in wet or chemical environments
• M2.5 x 0.45 thread size, 4 mm overall length for small-bore precision fitment
• 1.30 mm hex key drive for recessed, flush-mount installation
• Cup point geometry provides positive grip on shaft surfaces to resist rotation and axial displacement
• Box of 50 pieces supports production use and service stock

Compatibility

Designed as an OEM-style replacement or service fastener for metric assemblies requiring a DIN 916 M2.5 x 0.45 cup point set screw in stainless steel.

Installation Notes

Installation is performed by machinists or maintenance technicians using a calibrated 1.30 mm hex key driver. Ensure the mating shaft and bore are clean and free of debris before seating the screw. Do not overtighten - stainless steel fasteners at this thread size are susceptible to galling; apply an appropriate anti-seize compound if repeated removal is anticipated. Follow applicable equipment manufacturer torque guidance when specified in service documentation.
