Holo-krome 76568 M24 X 3.00 Hex Socket Cap Screw 100mm

Product Description

The HOLO-KROME 76568 is a metric hex socket cap screw in M24 x 3.00 thread size with a 100 mm length under head. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suited for heavy-duty fastening applications. The black oxide coating provides a baseline level of corrosion resistance and reduces light reflection on exposed hardware. Drive type is internal hex (Allen), allowing high torque application in confined spaces. This screw is partially threaded, consistent with standard cap screw geometry for clamping force on unthreaded shanks.

The 76568 is used in industrial machinery, structural assemblies, tooling fixtures, and mechanical equipment where high-strength metric fasteners are required. Its M24 coarse-pitch thread and grade 12.9 rating make it appropriate for joints that see significant load, vibration, or shear stress. Machinists, millwrights, and maintenance technicians are the primary installers in manufacturing and heavy equipment environments.

Key Features

• M24 x 3.00 metric coarse thread for broad compatibility with standard metric tapped holes
• Grade 12.9 alloy steel construction for maximum tensile and proof load ratings
• 100 mm length under head, partially threaded for proper clamping in bolted joints
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Internal hex (socket) drive accepts standard Allen wrenches and hex bit drivers
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed for use in any application requiring a DIN 912 or ISO 4762 compliant M24 x 3.00 metric hex socket cap screw in grade 12.9 alloy steel.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a properly sized hex key or socket driver. Always verify that the mating tapped hole meets M24 x 3.00 thread specification and is rated for grade 12.9 fastener loads before installation. De-energize and lock out all equipment before accessing the fastening location. Do not substitute a lower-grade fastener in joints designed for 12.9 hardware.
