Key Features & Benefits at a Glance
- Vibration-resistant locking with Nylon Patch thread locker ensures secure fastening in dynamic or high-stress environments.
- Exceptional tensile strength of 130,000 psi provides reliable load-bearing capacity for demanding industrial applications.
- Corrosion-resistant black-oxide finish on alloy steel enhances durability and extends service life in various operating conditions.
- Precise Class 3A thread fit guarantees tight tolerances and smooth assembly, reducing the risk of cross-threading.
- Wide temperature tolerance from -65° to 250°F maintains performance in extreme thermal environments.
- Fully threaded UNC coarse design allows for faster installation and superior grip in a range of materials.
- Hex drive compatibility with 3/32" drive enables easy installation and removal using standard tools.
Professional Applications & Engineering Value
Engineered for reliability, these black-oxide alloy steel flat head screws address critical challenges in industrial settings, such as vibration-induced loosening and material fatigue. The Nylon Patch thread locker effectively counters rotational forces, making them ideal for machinery, automotive assemblies, and electronic enclosures where consistent clamp load is essential. With a Rockwell C39 hardness and coarse UNC threading, they offer excellent resistance to stripping and wear, while the flat head design sits flush for streamlined profiles. These features collectively enhance assembly integrity, reduce maintenance needs, and support long-term operational safety in high-stress applications.
Specification Summary & Compliance
This screw adheres to Class 3A thread fit for precise dimensional accuracy and features UNC coarse thread spacing with full threading. Manufactured in compliance with ASTM F835 specifications, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe and sustainable use in global markets.
