Value Collection MP42758 Hex Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION MP42758 is a metric hex socket cap screw engineered for high-strength fastening applications. Sized at M8 x 1.25 with a 70 mm length under head, this partially threaded fastener is manufactured from alloy steel and finished with a black oxide coating. It carries a material grade of 12.9, indicating a tensile strength class suitable for demanding mechanical assemblies. The hex socket drive accepts a standard hex key or Allen wrench for installation. It meets DIN 912 and ISO 898-1 fastener standards, making it appropriate for precision engineering and industrial maintenance work.

This screw is commonly used in mechanical assemblies, machinery maintenance, equipment fabrication, and general industrial fastening where a high-grade metric socket cap screw is required. The black oxide finish provides modest corrosion resistance and reduces light reflection in exposed installations. It is suitable for use in both production environments and field service applications by maintenance technicians, millwrights, and industrial mechanics. The partial threading engages the full thread engagement depth appropriate for the specified mating material thickness.

Key Features

• M8 x 1.25 thread size with 70 mm length under head
• Partially threaded shank for precise clamping in through-hole assemblies
• Alloy steel construction with 12.9 material grade for high tensile strength
• Black oxide coating for corrosion resistance and reduced reflectivity
• Hex socket drive compatible with standard hex keys and Allen drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any M8 x 1.25 threaded hole requiring a grade 12.9 partially threaded fastener.

Installation Notes

Installation should be performed by qualified mechanical technicians using a correctly sized hex key or socket driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply appropriate thread lubrication or locking compound per the assembly specification. Do not exceed the rated clamp load for the 12.9 grade material when torquing.
