Holo-krome 760009994 M36 X 4.00 Hex Socket Cap Screw

Product Description

The HOLO-KROME 760009994 is a metric hex socket cap screw designed for high-load bolted joints in industrial and mechanical assemblies. It features an M36 x 4.00 thread profile with a 640 mm length under head, providing substantial clamping length for heavy structural connections. Manufactured from alloy steel to a Grade 12.9 material specification, it delivers high tensile and proof-load capacity well above standard fastener grades. The black oxide finish provides a base level of corrosion resistance and reduces surface reflectivity. Installation requires a hex socket drive. This fastener weighs 12.22 pounds per unit.

This screw is suited for heavy-duty mechanical, structural, and industrial applications where high-strength metric fasteners are required. Typical installations include machine frames, press assemblies, heavy equipment mounting, and structural steel connections. Its large diameter and extended shank length make it appropriate for thick-material stack-ups where standard-length cap screws fall short. Maintenance technicians, millwrights, and industrial mechanics are the primary installers. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, making it compatible with metric tooling and engineering specifications common in North American and international industrial environments.

Key Features

• Grade 12.9 alloy steel construction for high tensile strength under heavy load
• M36 x 4.00 thread size with 640 mm length under head for thick-material applications
• Hex socket drive for torque application with standard socket tooling
• Black oxide finish provides mild corrosion resistance and low-reflectance surface
• Conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as a metric hex socket cap screw conforming to ISO 4762 and ANSI B1.13M standards, suitable for use in any M36 x 4.00 threaded hole or nut requiring a Grade 12.9 fastener.

Installation Notes

Installation requires a properly sized hex socket driver capable of handling the torque demands of a Grade 12.9 M36 fastener. Power down or de-energize any equipment before fastener service on machinery. Consult the equipment manufacturer or applicable structural engineering specifications for required torque values, as Grade 12.9 fasteners require precise preload to perform correctly. Do not substitute lower-grade fasteners in joints specified for Grade 12.9.
