Value Collection SS6X05025-050BX M5 Set Screw Cup Point 18-8

Product Description

The VALUE COLLECTION SS6X05025-050BX is an M5 x 0.80 x 25 mm cup point set screw manufactured from grade 18-8 austenitic stainless steel (Grade A2). It meets DIN 916 standards and is driven by a 2.50 mm hex key. The cup point geometry bites into the mating shaft to resist rotation and axial movement without requiring a separate locking element. This fastener is suited for mechanical assemblies where corrosion resistance and reliable holding force are both required. Machinists, millwrights, and maintenance technicians working with metric hardware will find this screw a direct-fit option in standard M5 threaded bores.

This set screw is used in light to medium-duty mechanical assemblies including shaft collars, shaft couplings, pulleys, gears, and similar components requiring a flush or recessed fastener. Its stainless steel construction makes it appropriate for applications where mild corrosion exposure is a concern, such as food processing equipment, marine-adjacent environments, or outdoor machinery. The metric M5 x 0.80 thread pitch and 25 mm overall length serve a wide range of standard industrial and OEM applications.

Key Features

• Cup point geometry creates an indentation in the shaft for strong rotational and axial holding
• Grade 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance in moderate environments
• Meets DIN 916 fastener standard for consistent dimensional accuracy
• 2.50 mm hex key drive for precise torque application in tight spaces
• M5 x 0.80 metric thread for compatibility with standard metric bores
• 25 mm overall length suits medium-depth engagement applications

Compatibility

Designed for use in any standard M5 x 0.80 metric threaded bore requiring a DIN 916 cup point set screw. Suitable as a direct replacement or new installation in shaft collars, couplings, and similar mechanical components.

Installation Notes

Installation requires a 2.50 mm hex key driver. Ensure the threaded bore is clean and free of debris before driving the screw. Always de-energize and lock out any rotating or powered equipment before servicing fasteners on shafts or couplings. Do not exceed the torque capacity appropriate for M5 stainless fasteners as specified by the equipment manufacturer.
