S-90388A125 M6 x 16 mm ASME B18.3.4M, ISO 7380 Tamper-Resistant Torx Steel Button Head Screws

Key Features & Benefits at a Glance

• Enhanced tamper resistance with T27 Torx drive design, preventing unauthorized access in public or high-security installations
• Superior corrosion protection from black-oxide coating on alloy steel, extending service life in demanding industrial environments
• High-load bearing capacity with 130,000 psi tensile strength and Rockwell C38 hardness, ensuring reliable performance under stress
• Optimized thread engagement through Class 6g fit and coarse 1 mm pitch, enabling faster installation and vibration resistance
• Secure fastening in confined spaces with low-profile button head design (3.3 mm height), maintaining structural integrity while minimizing protrusion
• Full-thread coverage along the 16 mm length, providing consistent clamping force across the entire engagement surface
• Global compliance assurance meeting ASME, ISO, RoHS 3 and REACH standards, guaranteeing quality and environmental responsibility

Professional Applications & Engineering Value

Engineered for critical industrial applications where security and durability are paramount, these M6 metric screws with black-oxide alloy steel construction address common failure points in machinery, electronic enclosures, and public infrastructure. The tamper-resistant T27 Torx drive specifically counters vandalism and unauthorized maintenance in transportation systems, access control panels, and medical equipment. The fully threaded coarse pitch design ensures rapid assembly in production lines while maintaining vibration resistance in dynamic load conditions. With Rockwell C38 hardness and 130,000 psi tensile strength, these rounded head screws withstand repetitive stress cycles in automotive assemblies and heavy equipment without compromising the class 6g thread fit precision.

Specification Summary & Compliance

Manufactured to ASME B18.3.4M and ISO 7380 specifications with Class 6g thread tolerance for consistent metric threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Standard right-hand thread direction with 16 mm length and 10.5 mm head diameter maintains dimensional accuracy across production batches.
