Holo-krome 76810 M24 X 3.00 Hex Socket Cap Screw 55mm

Product Description

The HOLO-KROME 76810 is a metric hex socket cap screw engineered for high-load fastening applications in industrial, mechanical, and structural assemblies. Sized at M24 x 3.00 with a 55 mm length under head, this fastener is fully threaded and driven with a standard hex socket. The alloy steel construction meets Material Grade 12.9, the highest common strength class for metric fasteners, delivering exceptional tensile and proof load capacity. A black oxide finish provides moderate corrosion resistance and reduces surface reflectivity. This screw is installed by millwrights, maintenance mechanics, and machine technicians working on equipment requiring precision metric fastening.

This fastener suits a wide range of industrial and OEM applications including machine frames, hydraulic components, tooling fixtures, heavy equipment assemblies, and structural joints where high-strength metric hardware is required. The fully threaded M24 shank allows engagement along the full length of the fastener, making it well suited for through-bolting and blind-hole applications. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, ensuring dimensional interchangeability with metric hardware across global equipment platforms.

Key Features

• M24 x 3.00 thread size with 55 mm length under head
• Material Grade 12.9 alloy steel for maximum tensile strength
• Fully threaded shank for versatile fastening configurations
• Black oxide coating for mild corrosion and wear resistance
• Hex socket drive for high-torque installation in confined spaces
• Conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a direct-fit metric fastener for applications requiring M24 x 3.00 hex socket cap screws per ISO 4762 and ANSI B1.13M specifications. Dimensionally interchangeable with any M24 x 3.00 Grade 12.9 socket head cap screw meeting those standards.

Installation Notes

Installation is performed by qualified mechanics or technicians using a calibrated torque wrench and the correct metric hex key or socket bit. Grade 12.9 fasteners should be installed to manufacturer-specified torque values for the joint design - do not substitute a lower-grade fastener in a Grade 12.9 application. Ensure mating threads are clean and undamaged before installation. Thread lubricant or anti-seize may be used where specified by the equipment manufacturer.
