Holo-krome 760009990 Hex Socket Cap Screw M36 X 4.00

Product Description

The HOLO-KROME 760009990 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. With a thread size of M36 x 4.00 and a length under head of 600 mm (approximately 23.62 inches), this fastener handles demanding clamping loads where standard-grade hardware falls short. It is manufactured from alloy steel to material grade 12.9, the highest standard tensile class for metric fasteners, and finished with a black oxide coating that provides moderate corrosion resistance and a clean appearance. Installation requires a hex socket drive tool sized for M36 fasteners. Mechanical assemblers, millwrights, and heavy equipment technicians are the typical installers.

This screw is suited for heavy industrial equipment, large hydraulic machinery, structural steel assemblies, and fabrication applications that require a high-tensile metric cap screw. The M36 thread size and 600 mm shank length make it appropriate for thick-section joints, tie-rod applications, and deep-clearance bolted connections. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1, making it compatible with metric fastener specifications used across North American and international manufacturing environments.

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 standards
• 600 mm length under head suits deep-reach and thick-section bolted joints
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Hex socket drive for high-torque installation in confined or recessed locations

Compatibility

Designed as a standard metric hex socket cap screw per ISO 4762 and ANSI B1.13M, compatible with M36 x 4.00 tapped holes and metric nuts meeting ISO 898-1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the correct hex socket size for M36 fasteners. De-energize all equipment and relieve any hydraulic or pneumatic pressure before disassembling the joint. Apply thread lubricant or anti-seize compound as required by the joint specification to achieve accurate clamp load. Do not impact-drive grade 12.9 fasteners without confirming suitability, as shock loading can cause brittle fracture in high-tensile hardware.
