Holo-krome 760009985 Hex Socket Cap Screw M36 X 4.00

Product Description

The HOLO-KROME 760009985 is a metric hex socket cap screw engineered for high-strength fastening applications. It features an M36 x 4.00 thread size with a 560 mm (22.047 inches) length under head, manufactured from alloy steel with a black oxide finish. The grade 12.9 material classification places this fastener in the highest standard strength category for metric alloy steel cap screws, making it suitable for heavy-duty mechanical assemblies, structural connections, and precision machinery where clamping load and torque resistance are critical. The internal hex drive accepts a standard hex key for installation and removal in confined or recessed applications.

This fastener is used in industrial, commercial, and heavy equipment applications requiring a large-diameter, long-length metric cap screw. Typical installation scenarios include press frames, large bore machinery, structural steel assemblies, and fabricated equipment requiring a flush or recessed head profile. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, making it compatible with metric fastener specifications common in both domestic and internationally manufactured equipment. Installation is typically performed by millwrights, maintenance mechanics, or industrial assembly technicians.

Key Features

• Grade 12.9 alloy steel construction for maximum tensile and proof load capacity
• M36 x 4.00 thread form conforming to ANSI B1.13M and ISO 4762
• 560 mm (22.047 inches) length under head for deep-reach or long-grip applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Internal hex socket drive for high-torque installation with standard hex keys
• Sold individually, allowing single-piece procurement for repair and replacement use

Compatibility

Designed as a standard metric hex socket cap screw conforming to ISO 4762 and ANSI B1.13M, suitable for use in any application specifying an M36 x 4.00 grade 12.9 alloy steel socket head cap screw.

Installation Notes

Installation of large-diameter grade 12.9 cap screws should be performed by a qualified mechanic or millwright using a calibrated torque wrench to achieve the specified clamp load for the joint. Always de-energize, lock out, and tag out any equipment before removing or replacing structural fasteners. Do not substitute a lower-grade fastener in any joint originally specifying grade 12.9. Thread engagement depth and hole preparation should meet the requirements of the applicable engineering standard for the assembly.
