Value Collection 534302BR Flat Socket Cap Screw M20x2.5

Product Description

The VALUE COLLECTION 534302BR is a metric flat socket cap screw engineered for high-strength fastening applications. Built from 12.9 grade alloy steel with a black oxide finish, this fastener delivers tensile strength suitable for heavy-duty machine assembly, tooling fixtures, and structural connections where a flush or countersunk head profile is required. The 90-degree flat head seats into a countersunk hole, keeping the fastener surface flush with the mating component. Drive engagement is through a 12 mm hex socket. Installation requires a hex key or socket driver of the correct size. This screw is sold individually and is appropriate for mechanical maintenance professionals, machinists, and industrial assembly technicians.

This fastener is designed for metric applications conforming to DIN 7991. The M20x2.5 thread size and 80 mm overall length make it suited for medium-to-heavy structural assemblies, machine frames, and equipment housings where a low-profile countersunk head is specified. Partial threading allows engagement with thicker material sections. The black oxide coating provides mild corrosion resistance in dry or lightly oiled environments. Typically used in industrial maintenance, precision machining, and equipment fabrication settings.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load capacity
• 90-degree flat head profile seats flush in countersunk holes
• 12 mm hex socket drive for positive torque engagement
• Partially threaded shank provides grip length in thicker assemblies
• Black oxide finish offers mild corrosion resistance in controlled environments
• Conforms to DIN 7991 fastener standard for consistent dimensional accuracy

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in any M20x2.5 threaded countersunk application requiring a 12.9 grade fastener.

Installation Notes

Installation should be performed by a qualified mechanic or machinist using a calibrated hex key or socket driver. Ensure the mating hole is machined to the correct 90-degree countersink angle and thread specification before driving the fastener. Follow applicable torque specifications from the equipment manufacturer or relevant standards for 12.9 grade M20 fasteners. Do not reuse fasteners that show signs of thread damage, galling, or deformation.
