Key Features & Benefits at a Glance
- Exceptional tensile strength of 130,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Precise Class 3A thread fit provides superior engagement and vibration resistance, minimizing loosening in dynamic environments.
- Black-oxide coating on alloy steel offers enhanced corrosion resistance and a durable, non-reflective finish for long-term use.
- Fully threaded design allows for maximum grip length and consistent holding power along the entire fastener.
- 82° countersink angle and flat head enables a flush, secure fit in tapered seats, improving aesthetics and safety.
- 1/8" hex drive facilitates easy installation and high torque application with standard tools, speeding up assembly.
- Compliance with ASME B18.3, ASTM F835, RoHS 3, and REACH ensures adherence to industry standards and environmental regulations for global sourcing.
Professional Applications & Engineering Value
These 10-24 UNC flat head screws are engineered to address common industrial challenges such as vibration-induced loosening and corrosion in harsh environments. The Black-Oxide Alloy Steel construction, combined with a coarse thread and Class 3A fit, delivers superior clamp load retention and ease of installation in materials like metal and hardened plastics. Ideal for machinery, automotive assemblies, and electronic enclosures, the fully threaded design ensures uniform stress distribution, while the hex drive allows for efficient torque application without slippage. This makes them a reliable choice for engineers seeking high tensile strength and compliance with ASME B18.3 and ASTM F835 standards, enhancing overall assembly durability and reducing maintenance needs.
Specification Summary & Compliance
This product meets precise dimensional tolerances, including a Class 3A thread fit per UNC standards and an 82° countersink angle for optimal seating. It conforms to ASME B18.3 and ASTM F835 specifications, ensuring consistent quality and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, supporting environmentally responsible manufacturing and use in regulated industries.
