Metric Blue UST184001 Flat Socket Cap Screw M3x0.5

Product Description

The METRIC BLUE UST184001 is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener. It features a 90-degree flat head with a 2.00 mm hex socket drive and is fully threaded along its 16.00 mm overall length. The M3x0.5 thread size and 10.9 alloy steel construction provide high tensile strength in a compact form factor. The metric blue finish offers a degree of corrosion resistance and surface identification. This fastener conforms to DIN 7991 standards and is suited for precision assemblies, machinery, and equipment where a recessed head is required.

This screw is commonly used in mechanical assemblies, industrial equipment, electronics enclosures, and tight-clearance installations where a standard raised-head fastener would interfere with mating components. The flat head seats flush with or below the material surface, making it a standard choice for sheet metal, aluminum extrusions, and engineered plastic housings. Installation is performed with a 2.00 mm hex key or hex bit driver. It is sold individually but requires a minimum order of 100 units per order.

Key Features

• 90-degree flat head profile seats flush for low-clearance and recessed installations
• M3x0.5 metric thread size with full threading along the entire 16.00 mm length
• 10.9 alloy steel grade delivers high tensile and proof load strength
• 2.00 mm hex socket drive compatible with standard metric hex keys and bits
• Metric blue finish for surface protection and visual identification
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for M3x0.5 threaded holes in industrial machinery, precision equipment, and mechanical assemblies requiring a flush or countersunk fastener profile.

Installation Notes

Installation is typically performed by a machinist, assembler, or maintenance technician using a 2.00 mm hex key or drive bit. Ensure the mating hole is properly countersunk to 90 degrees to achieve full head seating. Do not exceed the torque rating for the 10.9 material grade or substitute a lower-grade fastener in high-load applications. Inspect threads and seating surfaces for debris before installation.
