Value Collection 532690BR Hex Socket Cap Screw M36x4 180mm

Product Description

The VALUE COLLECTION 532690BR is a metric hex socket cap screw with an M36 x 4.00 thread and 180 mm length under head, manufactured from alloy steel with a black oxide coating. This is a partially threaded, high-strength fastener rated to material grade 12.9, making it suitable for demanding structural and mechanical assemblies where precise clamping force and torque retention are required. The hex drive socket accepts a standard hex key or Allen wrench for installation and removal. At approximately 4.0 pounds per unit, this is a heavy-duty fastener intended for industrial, heavy equipment, and structural applications. It conforms to DIN 912 and ISO 898-1 fastener standards.

This screw is used in industrial machinery, heavy equipment assembly, structural steel fabrication, and mechanical engineering applications where an M36 coarse-pitch thread is specified. The black oxide finish provides mild corrosion resistance and reduces light reflection on exposed fastener heads. Partial threading is standard for this length class, allowing the unthreaded shank to bear shear loads in close-tolerance bored holes. Installation is typically performed by millwrights, maintenance mechanics, or structural assembly technicians working to engineered torque specifications for grade 12.9 fasteners.

Key Features

• M36 x 4.00 metric coarse thread, partially threaded, 180 mm length under head
• Alloy steel construction, material grade 12.9 for high tensile and proof load ratings
• Black oxide coating for mild corrosion resistance and reduced surface reflectivity
• Hex socket drive compatible with standard hex keys and Allen-drive tooling
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant M36 x 4.00 hex socket cap screw suitable for industrial machinery, heavy fabrication, and structural assemblies specifying a grade 12.9 alloy steel fastener in this thread and length class.

Installation Notes

Installation should be performed by qualified mechanical or structural personnel following the engineered torque specifications for grade 12.9 M36 fasteners as defined by the applicable design standard. Ensure mating threads are clean, free of debris, and that thread engagement depth meets minimum requirements per DIN or ISO guidelines before applying final torque. Always consult the assembly drawing or structural specification for lubrication requirements, as dry torque and lubricated torque values differ significantly at this fastener size. Do not substitute a lower material grade fastener in applications specifying grade 12.9.
