Key Features & Benefits at a Glance
- Enhanced tamper resistance with T15 Torx drive for secure installations in restricted-access environments
- Superior corrosion protection from black-oxide coating on alloy steel, extending service life in demanding conditions
- High-load capacity with 130,000 psi tensile strength and Rockwell C38 hardness for reliable performance under stress
- Precise thread engagement through Class 3A UNC coarse threading, ensuring vibration resistance and faster assembly
- Low-profile rounded head design providing smooth surface finish and reduced snagging in compact assemblies
- Full threading along 1/2" length for maximum grip depth and uniform load distribution across joined materials
- Regulatory compliance with ASME B18.3, RoHS, and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
Engineered for industrial machinery, electronic enclosures, and automotive assemblies, these 8-32 UNC T15 Torx rounded head screws address critical fastening challenges. The black-oxide alloy steel construction combats rust and wear in humid or high-friction environments, while the tamper-resistant Torx drive prevents unauthorized disassembly in public or safety-critical equipment. With coarse UNC threading and Class 3A fit, the screws maintain clamp force under vibration, reducing maintenance frequency. The fully threaded 1/2" length ensures consistent holding power in varied material thicknesses, making them ideal for production lines requiring repeatable, high-strength fastening solutions.
Specification Summary & Compliance
This fastener maintains Class 3A thread tolerance per UNC standards with coarse 8-32 threading and right-hand orientation. Manufacturing adheres to ASME B18.3 specifications for dimensional consistency. The screw is verified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting international environmental and safety regulations for industrial components.
