• Optimal torque transmission through the 1.5 mm hex drive design, preventing stripping during installation and maintenance
• Space-saving flat head profile with 90° countersink angle for flush mounting in confined spaces and streamlined designs
• Enhanced durability with Rockwell C32 hardness, maintaining structural integrity under repeated mechanical stress
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable and safe manufacturing practices

Professional Applications & Engineering Value

These M2.5 metric flat head screws deliver critical engineering solutions where space constraints meet high mechanical demands. The black-oxide alloy steel construction provides superior protection against oxidation and chemical exposure in industrial settings, while the Class 10.9 strength grade ensures reliable performance in vibration-prone equipment. The fully threaded design with coarse 0.45 mm pitch enables rapid installation and secure fastening in metals and engineered plastics. Ideal for precision machinery, automotive components, and electronic enclosures, these hex drive screws maintain clamping force under dynamic loads, reducing maintenance frequency and downtime in continuous operations.

Specification Summary & Compliance

Manufactured to precise metric thread standards with Class 6g tolerance for consistent fit. The right-hand coarse thread (M2.5 x 0.45 mm) and 5 mm length provide standardized compatibility across industrial components. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance restriction adherence. The flat head profile maintains 90° countersink angle specifications for uniform flush mounting in prepared seats.
