Value Collection MKFC04C020MBPKG M4x0.7 Flat Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION MKFC04C020MBPKG is a metric flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies, machine components, and precision equipment. Manufactured from grade 10.9 alloy steel and finished with a zinc-blue trivalent chromate coating, this fastener delivers high tensile strength and corrosion resistance without the use of hexavalent chromium. The M4x0.7 thread pitch and 20 mm overall length make it suitable for tight-clearance installations where a standard raised-head cap screw will not fit. Driven with a 2.50 mm hex socket key, it installs cleanly into countersunk holes. Each package contains 50 pieces.

This flat socket cap screw is suited for use in mechanical assemblies, industrial equipment, robotics, and fabrication projects requiring a flush-mount fastener. The fully threaded shank provides maximum thread engagement across the full 20 mm length, making it appropriate for thin material stacks and tapped-hole installations. Typical users include machinists, mechanical assemblers, maintenance technicians, and manufacturing engineers working in metric-standard environments.

Key Features

• Grade 10.9 alloy steel construction provides high tensile and proof load strength
• Zinc-blue trivalent chromate finish meets ROHS and REACH compliance requirements
• Fully threaded shank across the entire 20 mm length for maximum thread engagement
• 2.50 mm hex socket drive allows use in confined or flush-surface installations
• Conforms to DIN 7991 and ISO 10642 fastener standards
• Right-hand metric M4x0.7 thread for compatibility with standard metric tapped holes
• Sold in a 50-piece package to support production and service quantity needs

Compatibility

Designed as a metric flat socket cap screw conforming to DIN 7991 and ISO 10642 standards, suitable for use in any tapped M4x0.7 right-hand threaded hole requiring a countersunk flush-mount fastener.

Installation Notes

Installation requires a properly sized countersunk or flat-bottom counterbored hole to seat the head flush with or below the workpiece surface. Use a calibrated 2.50 mm hex key or bit to drive the fastener; avoid oversized or worn drivers that can strip the socket. Torque to the value specified by the assembly or equipment manufacturer for grade 10.9 M4 fasteners. Always ensure the mating tapped hole meets M4x0.7 metric thread specifications before installation.
