Metric Blue UST184154 Flat Socket Cap Screw M16x2 50mm

Product Description

The METRIC BLUE UST184154 is a metric flat socket cap screw engineered to DIN 7991 standards. It features a 90-degree flat head driven by a 10 mm hex socket and is manufactured from grade 12.9 alloy steel with a Metric Blue finish. At grade 12.9, this fastener delivers high tensile strength suited for demanding bolted joint applications where a flush or countersunk installation is required. The M16x2 thread size and 50 mm overall length make it a direct fit for medium-to-heavy structural and mechanical assemblies. Licensed mechanics, millwrights, and industrial maintenance technicians are the typical installers.

This flat socket cap screw is used in applications where a countersunk, low-profile head is needed to sit flush with or below a mating surface. Common installation scenarios include machinery frames, jigs, fixtures, and structural steel assemblies in both industrial and commercial settings. The fully threaded shank provides maximum thread engagement across the full 50 mm length, which is particularly useful in thin-plate and close-tolerance joint designs.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof-load strength
• 90-degree flat head countersunk profile for flush or recessed installations
• 10 mm hex socket drive for positive torque transfer with standard hex keys
• Fully threaded along the entire 50 mm length for maximum thread engagement
• Metric Blue finish for corrosion resistance and part identification
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M16x2 threaded bores in industrial machinery, structural assemblies, and mechanical equipment requiring a countersunk hex socket fastener.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate 10 mm hex socket key. Ensure the mating bore is properly countersunk to the correct 90-degree included angle before installation. De-energize and lock out all equipment per applicable safety procedures before servicing any fastened assembly. Do not reuse fasteners that show signs of thread damage, galling, or head deformation.
