Value Collection 534288BR Flat Socket Cap Screw M20x2.5

Product Description

The VALUE COLLECTION 534288BR is a metric flat socket cap screw engineered for high-strength fastening applications. Built to DIN 7991 specifications, it features a 90-degree flat head with a hex socket drive, making it suitable for flush or countersunk installations where a low-profile fastener is required. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this screw offers high tensile strength and moderate corrosion resistance. The M20x2.5 thread size and 45mm overall length make it a heavy-duty fastener appropriate for precision mechanical assemblies, tooling, and structural connections requiring a fully threaded shaft.

This fastener is used in industrial, mechanical, and structural applications where a countersunk socket cap screw is required to sit flush with or below the mating surface. The Grade 12.9 rating indicates very high tensile strength, making this screw suitable for high-load bolted joints in machinery, fixtures, dies, and equipment frames. It is commonly installed by machinists, millwrights, and maintenance technicians working in manufacturing or industrial maintenance environments. Minimum order quantity is 10 pieces.

Key Features

• Grade 12.9 alloy steel construction provides very high tensile and proof load strength
• Black oxide finish delivers moderate corrosion resistance and a low-reflectance appearance
• 90-degree flat head with hex socket drive allows flush or countersunk installation
• Fully threaded M20x2.5 shank along 45mm overall length
• Conforms to DIN 7991 fastener standard for dimensional consistency
• 12mm hex socket drive size for standard tooling compatibility

Compatibility

Designed as a metric-standard countersunk socket cap screw for use in any application requiring a DIN 7991-compliant M20x2.5 flat head fastener with a 45mm overall length.

Installation Notes

Installation requires a 12mm hex key or hex socket driver. Ensure the receiving hole is countersunk to a 90-degree angle to match the flat head geometry before installation. Torque to the value specified by the joint designer or applicable engineering standard for Grade 12.9 fasteners of this thread size. Always confirm thread engagement depth and mating material compatibility before final assembly.
