Holo-krome 76224 Hex Socket Cap Screw M8 X 1.25 12mm

Product Description

The HOLO-KROME 76224 is a metric hex socket cap screw engineered for high-strength fastening applications. It features an M8 x 1.25 thread profile with a 12 mm length under head and is fully threaded from head to tip. Manufactured from grade 12.9 alloy steel with a black oxide coating, this fastener delivers high tensile strength and moderate corrosion resistance in a compact, low-profile head format. The internal hex drive allows torque to be applied in tight clearance areas where a wrench cannot reach. It conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, making it a recognized choice for precision mechanical assemblies.

This screw is suited for use in mechanical, industrial, and manufacturing environments where high-clamping force and accurate thread engagement are required. Typical applications include machinery frames, jigs and fixtures, hydraulic components, and fabricated assemblies where a flush or low-profile fastener head is preferred. The fully threaded configuration ensures maximum thread engagement across the full length of the fastener, which is particularly useful in short blind-hole applications. Licensed trades and industrial maintenance technicians regularly specify grade 12.9 socket cap screws in applications governed by engineered load requirements.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded M8 x 1.25 thread form for maximum engagement in short blind holes
• Internal hex drive allows installation in recessed or tight-clearance locations
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 dimensional and material standards

Compatibility

Designed as a standard metric hex socket cap screw for use in any application requiring an M8 x 1.25 thread form and a 12 mm length under head per DIN 912 and ISO 4762 specifications.

Installation Notes

Installation requires a properly sized hex key or Allen driver matched to the M8 socket head to avoid cam-out and drive damage. Always verify thread engagement depth and hole condition before fastening. Grade 12.9 fasteners should not be substituted for lower-grade hardware without confirming the joint design allows it. Follow applicable mechanical or structural standards for torque requirements based on the application and mating material.
