Metric Blue UST187485 M5x0.80 Button Socket Cap Screw

Product Description

The METRIC BLUE UST187485 is a fully threaded M5x0.80 button socket cap screw manufactured from Grade 12.9 alloy steel with a blue phosphate finish. Designed to ISO 7380 standards, this fastener features a low-profile domed button head driven by a 3.00 mm hex socket. The 25 mm length under head provides positive thread engagement across a range of clamping applications. Grade 12.9 alloy steel delivers high tensile strength suited to demanding mechanical assemblies. The blue phosphate coating provides corrosion resistance and consistent surface hardness. This screw is specified by mechanical assemblers, machine builders, and maintenance technicians working in metric-dimensioned assemblies.

This fastener is used in light to medium-duty industrial and mechanical applications where a low-profile head is required and clearance above the fastened surface is limited. The button head profile distributes clamping load over a wider bearing area than a standard socket head cap screw, making it well suited for sheet metal, enclosures, brackets, and precision machine components. It is installed with a standard 3.00 mm hex key or hex socket bit driver. This SKU is sold individually but requires a minimum order of 100 pieces.

Key Features

• Grade 12.9 alloy steel construction for high tensile strength and fatigue resistance
• Fully threaded M5x0.80 thread profile conforming to metric thread standards
• Low-profile button head reduces protrusion above fastened surface
• 3.00 mm hex socket drive for precise torque application
• Blue phosphate finish provides corrosion resistance
• Manufactured to ISO 7380 fastener standard

Compatibility

Designed as a metric ISO 7380 button socket cap screw for use in any assembly accepting an M5x0.80 fully threaded fastener with a button head profile.

Installation Notes

Install and remove with a 3.00 mm hex key or hex socket bit driver. Ensure mating threads are clean and free of debris before driving. Do not exceed the torque rating specified for Grade 12.9 M5 fasteners per the assembly manufacturer or relevant engineering standard. Inspect threads for damage before reuse in critical load-bearing joints.
