Value Collection FHS1X02506-050BX Flat Socket Cap Screw M2.5x0.45

Product Description

The VALUE COLLECTION FHS1X02506-050BX is a metric flat socket cap screw engineered for precision fastening applications where a flush or countersunk head profile is required. This screw features an M2.5x0.45 thread, a 6 mm overall length, and a 90-degree flat head driven by a 1.50 mm hex socket. Constructed from 18-8 austenitic Grade A2 stainless steel, it offers reliable corrosion resistance in moderate environments. The fastener is fully threaded and conforms to DIN 7991 standards, making it a dependable choice for metric assembly work across manufacturing, instrumentation, and light mechanical applications.

This flat socket cap screw is suited for applications requiring a low-profile, flush-seating fastener in tight clearance assemblies. Common use cases include precision instrument housings, enclosures, electronic hardware, and small mechanical assemblies where a protruding head would interfere with mating components. The metric thread size and stainless steel construction make it appropriate for both indoor and light outdoor installations where corrosion resistance is a factor. Installers and assembly technicians working with metric hardware will find this screw fits standard metric countersunk hole patterns per DIN 7991 specifications.

Key Features

• M2.5x0.45 metric thread with 6 mm overall length for small-fastener precision applications
• 90-degree flat head profile provides flush seating in countersunk holes
• 1.50 mm hex socket drive for precise torque application with standard metric hex keys
• Fully threaded shank along the entire 6 mm length
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance
• Manufactured to DIN 7991 fastener standard for consistent dimensional compliance

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw compatible with standard M2.5x0.45 countersunk metric threaded holes in precision assemblies and light mechanical hardware.

Installation Notes

Installation requires a 1.50 mm hex key or hex socket driver sized for metric fasteners. Ensure the mating hole is properly countersunk to a 90-degree angle before driving the screw to achieve full flush seating. Do not exceed the recommended torque range for M2.5 stainless steel fasteners, as over-torquing small-diameter stainless screws can cause galling or thread failure. Clean threads and mating surfaces before installation to ensure consistent engagement.
