Holo-krome 76906 M36 X 4.00 Hex Socket Cap Screw 100mm

Product Description

The HOLO-KROME 76906 is a fully threaded hex socket cap screw designed for high-strength mechanical fastening applications. It features an M36 x 4.00 metric thread profile and a 100 mm length under head, manufactured from alloy steel with a black oxide coating. At Material Grade 12.9, this fastener delivers exceptional tensile strength, making it suitable for heavy-duty assemblies where fastener integrity under load is critical. The black oxide finish provides moderate corrosion resistance and reduces light reflection. This screw is installed using a hex drive tool and is commonly specified by mechanical engineers, millwrights, and industrial maintenance technicians.

This fastener is suited for industrial and commercial applications requiring large-diameter, high-strength metric socket cap screws. Typical installation scenarios include heavy machinery assembly, structural bolted connections, tooling fixtures, and equipment maintenance where M36 metric fasteners are called for. The fully threaded design allows engagement along the entire shank length, maximizing thread contact in through-hole or deep-socket applications.

Key Features

• M36 x 4.00 metric thread for large-diameter high-load fastening
• 100 mm length under head, fully threaded
• Alloy steel construction at Material Grade 12.9 for maximum tensile strength
• Black oxide coating for corrosion resistance and low-glare finish
• Hex socket drive for high-torque installation with standard Allen or socket tooling
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-specification metric hex socket cap screw for industrial machinery, heavy equipment, and structural assemblies requiring M36 x 4.00 Grade 12.9 fasteners conforming to ISO 4762 and ANSI B1.13M standards.

Installation Notes

Installation should be performed by a qualified millwright, mechanical technician, or maintenance professional using a properly sized hex key or socket drive rated for high-torque applications. De-energize and lockout-tagout all associated equipment before disassembling or replacing fasteners in powered machinery. Do not substitute a lower-grade fastener in applications specifying Grade 12.9. Verify thread engagement depth and mating thread condition before final assembly.
