Holo-krome 76573 Hex Socket Cap Screw M24 X 3.00 Alloy Steel

Product Description

The HOLO-KROME 76573 is a metric hex socket cap screw engineered for high-strength fastening in demanding industrial and mechanical applications. It features an M24 x 3.00 thread with a 130 mm length under head, partial threading, and is manufactured from alloy steel with a black oxide finish. At material grade 12.9, this fastener delivers the tensile strength required for critical bolted joints in heavy equipment, tooling fixtures, and structural assemblies. The hex socket drive accepts a standard hex key or Allen-style bit for controlled torque installation in confined spaces.

This screw is suited for use in machine tool assemblies, hydraulic and pneumatic equipment, industrial presses, and structural steel fabrication where high clamping force and precise torque are required. The partial threading is typical for larger-diameter cap screws, providing a shank section that improves shear load performance. Maintenance technicians, millwrights, and industrial mechanics will encounter this fastener in both OEM builds and field repair scenarios.

Key Features

• Material grade 12.9 alloy steel for maximum tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• M24 x 3.00 metric thread per ANSI B1.13M, DIN 912, and ISO 4762 standards
• Partially threaded shank improves shear resistance in load-bearing joints
• Hex socket drive allows installation in recessed or close-clearance locations
• Conforms to ISO 898-1 for mechanical property requirements

Compatibility

Designed as a direct-fit fastener for applications specifying DIN 912 or ISO 4762 hex socket cap screws in M24 x 3.00 thread size at 130 mm length under head.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or trained technicians using a calibrated torque wrench with the appropriate hex bit or Allen key. Ensure mating threads are clean and free of debris before installation, and apply thread lubricant or anti-seize compound only where called for by the equipment manufacturer. Grade 12.9 fasteners should not be reused in critical joints after being torqued to yield. Follow equipment OEM torque specifications for the M24 thread size and joint material.
