Professional Applications & Engineering Value
Engineered for demanding industrial applications, this M4 flat head screw combines black-oxide alloy steel with a Class 10.9 strength rating to address common challenges like vibration loosening and material fatigue. The fully threaded coarse pitch (0.7mm) and standard 90° countersink angle enable flush mounting in metal frameworks, machinery, and automotive components, reducing protrusion risks. With Rockwell C32 hardness and 120,000 psi tensile strength, it withstands heavy loads while the hex drive simplifies maintenance in confined spaces. Ideal for assembly lines requiring metric coarse thread reliability, this screw meets DIN 7991/ISO 10642 standards for consistent performance in OEM and MRO settings.
Specification Summary & Compliance
This fastener adheres to Class 6g thread tolerance for metric coarse threads (M4 x 0.7mm) and is manufactured per DIN 7991/ISO 10642 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The flat head profile and 10mm length maintain dimensional precision for seamless integration into standardized assemblies.
