Holo-krome 76572 Hex Socket Cap Screw M24 X 3.00 120mm

Product Description

The HOLO-KROME 76572 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features an M24 x 3.00 thread size with a length under head of 120 mm (approximately 4.72 inches), partially threaded shank, and is manufactured from alloy steel at a Grade 12.9 material rating - one of the highest strength classes available for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces surface reflectivity. The internal hex drive requires a matching hex key or Allen driver for installation and removal.

This screw is suited for demanding mechanical and industrial applications where high clamp load and tensile strength are required. It is commonly used in machine tool assemblies, heavy equipment, hydraulic components, and structural fixtures. The partially threaded shank provides a bearing surface that helps resist shear loads in bolted joints. Installation is performed by machinists, millwrights, maintenance technicians, and mechanical contractors working with metric-standard hardware.

Key Features

• M24 x 3.00 thread size with 120 mm length under head (approximately 4.72 inches)
• Grade 12.9 alloy steel construction for maximum tensile and yield strength
• Partially threaded shank provides shear-load resistance in precision joints
• Black oxide finish for mild corrosion protection and reduced glare
• Internal hex socket drive for high-torque installation in confined spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit metric hex socket cap screw conforming to DIN 912 and ISO 4762 standards, compatible with any M24 x 3.00 threaded bore requiring a Grade 12.9 partially threaded cap screw.

Installation Notes

Installation and removal require a correctly sized hex key or Allen driver rated for the applied torque; use of an undersized or worn driver can damage the socket recess. Verify thread engagement depth and mating material strength before applying full torque, as Grade 12.9 fasteners can exceed the capacity of softer base materials. De-energize or lock out any equipment before accessing fastener locations in live machinery, following applicable OSHA lockout/tagout procedures.
