• Optimized thread engagement with Class 6g thread fit and coarse 1.25mm pitch, facilitating quick assembly and reducing cross-threading risks.
• Space-saving low-profile head design allows installation in confined areas while maintaining a high clamp force.
• Versatile partially threaded shank enables precise clamping on specific sections, ideal for components requiring targeted fastening pressure.
• Guaranteed dimensional consistency and material integrity, manufactured to meet DIN 6912 specifications for dependable interchangeability.

Professional Applications & Engineering Value

This M8 socket head cap screw is engineered to address critical challenges in machinery assembly, automotive manufacturing, and heavy equipment. The black-oxide alloy steel construction combats rust and wear, essential for operations exposed to oils, moisture, or varying temperatures. Its partially threaded design ensures that unthreaded sections bear directly against components, distributing load efficiently and preventing loosening under vibration. The low-profile socket head with a pilot recess offers a flush fit, reducing protrusion in compact designs while the hex drive allows high torque application without stripping. Complying with DIN 6912, these metric screws deliver reliable performance in high-stress applications, from conveyor systems to precision tooling, where Class 8.8 strength and consistent thread fit are non-negotiable for safety and longevity.

Specification Summary & Compliance

This screw features M8 x 1.25mm coarse metric thread with Class 6g tolerance for precise fit, a partially threaded shank with minimum 13mm thread length, and overall 20mm length. Manufactured from alloy steel with Rockwell C20 hardness, it meets DIN 6912 dimensional and mechanical specifications. The product is RoHS 3 (2015/863/EU) compliant, ensuring it is free from hazardous substances for safe use in regulated industries.
