Value Collection 534266BR Flat Socket Cap Screw M16x2

Product Description

The VALUE COLLECTION 534266BR is a metric flat socket cap screw manufactured from 12.9 grade alloy steel with a black oxide finish. The 90-degree flat head seats flush with or below the mating surface, making it well suited for applications where a low-profile or countersunk fastener is required. Drive engagement is through a 10 mm hex socket. The M16x2 thread is partially threaded along an 80 mm overall length. At grade 12.9, this fastener delivers high tensile and proof-load strength, appropriate for heavy-duty mechanical assemblies. Licensed tradespeople, machinists, and maintenance technicians working on industrial equipment, tooling, and structural assemblies are the primary installers.

This fastener is used in metric-standard mechanical assemblies requiring a flush or countersunk head profile. Typical applications include machine tool frames, fixture plates, hydraulic component mounting, and structural steel fabrication where a protruding head would interfere with adjacent surfaces or moving parts. The partial threading allows for a stronger grip in thick material sections. Conformance to DIN 7991 ensures dimensional consistency across metric hardware ecosystems used in industrial and manufacturing environments.

Key Features

• 12.9 alloy steel grade for high tensile strength in demanding assemblies
• 90-degree flat head design seats flush or countersunk to clear mating surfaces
• 10 mm hex socket drive for high-torque installation with standard hex keys or socket tooling
• Partially threaded shank provides shear strength and accurate positioning in thick-section joints
• Black oxide finish offers mild corrosion resistance and reduces light reflection in precision equipment
• Manufactured to DIN 7991 for consistent metric dimensional compliance

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M16x2 threaded holes in industrial machinery, fixtures, and structural assemblies requiring a countersunk hex-socket fastener.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 10 mm hex key or socket driver. Ensure the mating countersink angle matches 90 degrees before installation. Thread engagement depth should comply with applicable engineering standards for the base material type. Do not use impact tooling that exceeds the rated drive engagement for the socket size.
