Value Collection 534286BR M20x2.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534286BR is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built to DIN 7991 standard, this screw features a 90-degree flat head driven by a hex socket and is fully threaded along its 40 mm overall length. The M20x2.5 thread size and 12.9 alloy steel construction make it suitable for high-strength bolted joints where a low-profile head is required. A black oxide finish provides mild corrosion resistance and a uniform appearance. Maintenance technicians, machinists, and millwrights commonly install these fasteners in machine assemblies, fixtures, and structural components.

This flat socket cap screw is used in metric-threaded assemblies across industrial, manufacturing, and mechanical maintenance applications. The 90-degree countersunk head seats flush with or below the mating surface, keeping the joint profile clean and snag-free. Fully threaded construction ensures consistent engagement through the full fastener length, making it appropriate for through-hole and tapped applications where maximum thread contact is needed.

Key Features

• DIN 7991 standard for consistent dimensional conformance in metric assemblies
• 12.9 alloy steel grade for high tensile and proof load strength
• 90-degree flat head seats flush in countersunk holes to eliminate protrusion
• Hex socket drive for high torque input in confined spaces
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Fully threaded along entire 40 mm length for maximum thread engagement

Compatibility

Designed for use in M20x2.5 metric-threaded countersunk holes conforming to DIN 7991 specifications in industrial machinery, fixtures, and fabricated assemblies.

Installation Notes

Installation requires a correctly sized hex socket or hex key rated for high-strength fasteners. Ensure the countersunk hole geometry matches the 90-degree included angle before installation. Apply appropriate thread-locking compound or torque per the equipment manufacturer's specifications. Always de-energize and lock out equipment before servicing fastened assemblies in powered machinery.
