Key Features & Benefits at a Glance
- Vibration-resistant locking with Nylon Patch thread locker ensures secure fastening in high-motion environments, preventing loosening under stress.
- Exceptional tensile strength of 170,000 psi provides reliable performance in heavy-duty and high-load applications.
- Thermal stability with an operating range of -70° to 250°F maintains integrity in extreme temperature conditions.
- Precise Class 3A thread fit offers superior engagement and reduces the risk of cross-threading in critical assemblies.
- Durable black-oxide coating on alloy steel enhances corrosion resistance and extends service life in harsh industrial settings.
- Hex socket drive design allows for high-torque installation and easy access in confined spaces.
- Compliance with ASME B18.3 and environmental standards ensures consistent quality and adherence to RoHS 3 and REACH regulations.
Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 10-32 UNF socket head cap screw addresses common challenges like vibration-induced loosening and thermal expansion. The Nylon Patch thread locker provides reliable locking without requiring additional adhesives, making it ideal for machinery, automotive, and aerospace applications where maintenance access is limited. Constructed from black-oxide alloy steel with a Rockwell C37 hardness, it withstands high stress and corrosive conditions, while the fine UNF thread and Class 3A fit ensure precise alignment and load distribution. These features make it a top choice for assemblies requiring repeated disassembly and reassembly without performance degradation.
Specification Summary & Compliance
This screw features a 10-32 UNF fine thread with Class 3A thread fit for high precision, a partially threaded design, and a length of 2 inches. It meets ASME B18.3 specifications and is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and consistent performance in regulated industries.
