The fastener measures 220 millimeters in length under the head and is manufactured from alloy steel to Grade 12.9, the highest standard strength class for metric hex socket cap screws. A black oxide coating provides mild corrosion resistance and reduces surface glare. This screw is driven with a hex key (Allen wrench) and is suited for high-load structural assemblies where a recessed drive profile is required. Mechanical contractors, millwrights, and industrial maintenance technicians are the primary installers of this fastener class.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy mechanical assemblies, machine frames, hydraulic component mounting, press tooling, and structural steel fabrication where metric threading and high clamping force are required. The M36 x 4.00 thread pitch and 220-millimeter shank length make it appropriate for thick-section bolted joints. Compliance with ANSI B1.13M, ISO 4762, and ISO 898-1 standards ensures dimensional and mechanical property consistency across sourcing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for maximum tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eM36 x 4.00 metric thread for heavy-duty bolted connections\u003c\/li\u003e\n  \u003cli\u003e220-millimeter length under head accommodates thick-section joints\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for high-torque installation in confined or recessed mounting locations\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B1.13M, ISO 4762, and ISO 898-1 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric hex socket cap screw for industrial machinery, structural steel assemblies, and heavy mechanical equipment requiring M36 x 4.00 thread fasteners conforming to ISO 4762 and ANSI B1.13M specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of Grade 12.9 fasteners should be performed by qualified mechanical or industrial trades personnel familiar with metric torque specifications and joint design. Always verify thread engagement depth and mating thread condition before installation. Follow applicable ASME or ISO bolted-joint standards for torque sequencing and preload requirements.
