Key Features & Benefits at a Glance
- Superior corrosion resistance from high-quality brass material, ensuring long-term reliability in harsh industrial environments.
- Exceptional tensile strength of 70,000 PSI provides secure, vibration-resistant fastening for demanding applications.
- Class 6g thread fit with coarse 0.45 mm pitch enables quick, easy installation and reduces cross-threading risks.
- 1.5 mm hex drive design offers enhanced torque transmission and slip-resistant engagement during assembly.
- Full threading along the 8 mm length ensures maximum grip and uniform load distribution across joined materials.
- Rockwell B55 hardness rating maintains thread integrity and resists wear under repeated use.
- Compliance with DIN 7991, RoHS 3, and REACH guarantees adherence to international safety and environmental standards.
Professional Applications & Engineering Value
Engineered for precision and durability, these M2.5 brass flat head screws address common industrial challenges like corrosion, vibration loosening, and assembly efficiency. The hex drive and coarse thread pitch simplify installation in tight spaces, reducing labor time while the 90° countersink angle ensures a flush fit for streamlined surfaces. Ideal for electronics, machinery, and automotive components, the fully threaded design and Class 6g metric thread provide consistent clamping force, preventing joint failure in high-stress environments. Made from lead-free brass, they offer inherent antimicrobial properties and electrical conductivity, making them suitable for electrical enclosures and medical devices where hygiene and safety are critical.
Specification Summary & Compliance
This screw features a metric M2.5 x 0.45 mm coarse thread with Class 6g tolerance for precise fit, and an 8 mm length with full threading. It conforms to DIN 7991 manufacturing standards and is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I for lead as an alloying element, alongside full REACH (EC 1907/2006) adherence as of June 2023, ensuring environmental and safety regulations are met.
