Key Features & Benefits at a Glance
- Exceptional tensile strength of 130,000 psi ensures reliable performance in demanding industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel prolongs service life in harsh environments, minimizing maintenance needs.
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, enhancing joint integrity.
- Hex drive design with 1/8" drive size allows for easy installation and high torque application, speeding up assembly processes.
- 82° countersink angle and flat head enables a flush fit in tapered seats, improving aesthetics and preventing snagging.
- Partially threaded shank offers optimal grip on materials without unnecessary threading, ensuring efficient clamping force.
- Compliance with ASTM F835 and environmental regulations guarantees quality and safety, supporting sustainable procurement practices.
Professional Applications & Engineering Value
These 10-24 UNC flat head screws are engineered to address common industrial challenges, such as vibration loosening and corrosion in heavy machinery. The black-oxide alloy steel construction, combined with a coarse thread and Class 3A thread fit, ensures a secure, durable connection that withstands high-stress conditions in automotive, aerospace, and construction sectors. The hex drive facilitates quick installation with standard tools, reducing labor time, while the partially threaded design concentrates force where needed, preventing material damage. Ideal for applications requiring reliable fastening solutions, these screws deliver long-term performance and compliance with industry standards.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including a Class 3A thread fit and UNC coarse threading for consistent engagement. It meets ASTM F835 specifications for mechanical properties, ensuring high tensile strength and hardness (Rockwell C39). Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material restrictions.
