Value Collection MP42757 Hex Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION MP42757 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. Manufactured from alloy steel with a black oxide finish, this screw carries a material grade of 12.9, indicating exceptional tensile strength suitable for demanding clamping and structural connections. The M8 x 1.25 thread size with a 60 mm length under head makes it a standard choice for medium-duty metric fastening where a flush, recessed-drive installation is required. Licensed trade professionals and maintenance technicians reach for this hardware in production, maintenance, and equipment repair settings.

This screw is suited for use in general industrial machinery, precision tooling, structural assemblies, and equipment where metric fasteners conforming to DIN 912 and ISO 898-1 standards are specified. The partially threaded shank provides a smooth bearing surface in the grip zone, which improves joint integrity in applications where shear loads are present. It is commonly installed in fabrication shops, manufacturing facilities, and maintenance environments requiring repeatable, high-clamp-force fastening.

Key Features

• M8 x 1.25 metric thread with 60 mm length under head for standard medium-duty metric fastening
• Material grade 12.9 alloy steel provides high tensile strength and fatigue resistance
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance
• Partially threaded shank improves shear load performance and joint stability
• Internal hex drive (socket head) allows torque application in confined spaces using a standard Allen key or hex driver
• Conforms to DIN 912 and ISO 898-1 fastener standards for consistent dimensional and mechanical performance

Compatibility

Designed as an OEM-compatible replacement or stock fastener for metric assemblies requiring an M8 x 1.25 socket cap screw per DIN 912 and ISO 898-1 specifications.

Installation Notes

Installation is performed using a properly sized hex key or socket driver matched to the M8 socket head. Ensure mating threads are clean and free of debris before installation. Grade 12.9 fasteners should not be substituted in applications rated for lower-grade hardware without engineering review. Follow applicable torque specifications for the assembly and material being joined, as listed in the equipment manufacturer documentation or relevant industry standards.
