The HOLO-KROME 76552 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile strength and is suited for demanding load-bearing joints. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. At 65 mm in length under the head with a fully threaded shank, the M24 x 3.00 thread profile makes it a standard choice for machine builders, maintenance technicians, and fabricators working with metric fastener systems.
This screw is used in industrial machinery, hydraulic equipment, structural fabrication, and heavy equipment maintenance wherever a high-strength metric socket cap fastener is required. The M24 x 3.00 thread size and 65 mm under-head length suit medium-to-heavy flange connections, mounting plates, and bolted joints that require torque-intensive installation. It is installed with a standard hex (Allen) key or socket driver. Compliance with ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 makes this screw appropriate for applications where fastener standards must be documented.
Designed as a standard metric hex socket cap screw for any application requiring an M24 x 3.00 thread, fully threaded, grade 12.9 fastener per DIN 912 and ISO 4762 specifications.
Installation is performed by qualified mechanical technicians or tradespeople using a correctly sized hex key or hex socket driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound as required by the joint specification to achieve accurate clamp load at the target torque. Do not mix metric and unified inch fasteners in the same joint.
