Value Collection 534294BR Flat Socket Cap Screw M20x2.5

Product Description

The VALUE COLLECTION 534294BR is a metric flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. Built to DIN 7991, it features a 90-degree flat head with a hex socket drive and is manufactured from 12.9 grade alloy steel with a black oxide finish. The M20x2.5 thread and 60 mm overall length make it well suited for heavy-duty mechanical assemblies where high tensile strength and a low-profile head are required. This is a fully threaded fastener. Licensed tradespeople and machine maintenance technicians are the primary installers.

This flat socket cap screw is used in industrial, manufacturing, and mechanical maintenance settings where a countersunk fastener is needed to sit flush with or below a mating surface. Typical applications include machine frames, fixtures, tooling plates, and structural assemblies requiring high clamp load. The 12.9 alloy steel grade delivers tensile strength suitable for demanding static and dynamic load conditions. The black oxide coating provides moderate corrosion resistance and reduces light reflection in precision environments.

Key Features

• DIN 7991 fastener standard for predictable dimensional and mechanical conformance
• 12.9 alloy steel material grade for high tensile and proof load capacity
• 90-degree flat head allows flush or countersunk seating in mating materials
• Hex socket drive accepts standard metric hex keys and socket bits
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• Fully threaded along the entire shank length

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw for use in any application specifying an M20x2.5 thread, 60 mm overall length, and 90-degree countersunk head geometry.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical maintenance technicians using a properly sized metric hex key or hex socket driver. The mating material must be drilled and countersunk to the correct 90-degree angle to ensure full head seating and proper clamp load distribution. Verify thread engagement depth and countersink geometry before final torque. Do not substitute an imperial hex driver, as rounding the socket will damage the fastener head.
