Key Features & Benefits at a Glance
- Enhanced tamper resistance with a specialized hex drive that deters unauthorized removal, ideal for secure installations.
- Superior corrosion resistance thanks to 18-8 stainless steel and a passivated finish, ensuring longevity in harsh environments.
- High tensile strength of 80,000 PSI and Rockwell B96 hardness for reliable load-bearing and mechanical durability.
- Precise Class 6g thread fit and coarse M4 x 0.7mm threading for easy installation and strong holding power.
- Fully threaded design maximizes grip and distribution of stress along the entire 10mm length.
- Compliance with ASTM F879M, RoHS 3, and REACH ensures safety, environmental responsibility, and industry-standard quality.
- Low-profile button head with a rounded design minimizes protrusion and reduces snagging in compact assemblies.
Professional Applications & Engineering Value
This M4 tamper-resistant hex button head screw is engineered to address critical challenges in industrial and security-focused applications. Made from 18-8 stainless steel with a passivated finish, it resists oxidation and chemical exposure, making it suitable for outdoor equipment, electronics enclosures, and machinery in corrosive settings. The tamper-resistant hex drive prevents unauthorized access, while the fully threaded coarse pitch ensures quick, secure fastening in metals and plastics. Its rounded head profile reduces the risk of injury and interference, providing a flush fit in assemblies where space and safety are priorities. Ideal for securing access panels, public infrastructure, and high-value assets, this screw combines durability with compliance to meet rigorous engineering demands.
Specification Summary & Compliance
This screw features a metric M4 x 0.7mm coarse thread with a Class 6g thread fit for precise dimensional accuracy. It is fully threaded and measures 10mm in length, with a head diameter of 7.59mm. The product conforms to ASTM F879M specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
