Key Features & Benefits at a Glance
- Vibration-resistant locking with permanent nylon patch ensures reliable fastening in high-stress environments, eliminating the need for additional locking hardware.
- Superior corrosion resistance from 18-8 Stainless Steel construction provides long-lasting performance in harsh or outdoor industrial settings.
- High tensile strength of 70,000 psi and Rockwell B55 hardness deliver exceptional durability and load-bearing capacity for demanding applications.
- Wide temperature tolerance (-70° to 250° F) maintains locking integrity across extreme thermal cycles, ideal for automotive or machinery uses.
- Precise Class 3A thread fit with UNC coarse threading ensures easy installation and secure engagement, reducing assembly time and errors.
- Hex drive design allows for high-torque application with standard tools, enhancing installation efficiency and grip.
- Full threading provides consistent clamping force along the entire length, improving joint stability in dynamic loads.
Professional Applications & Engineering Value
This 10-24 UNC screw with nylon patch locking addresses critical challenges in industrial assembly, where vibration loosening can compromise safety and performance. Made from 18-8 Stainless Steel, it resists rust and chemical exposure in environments like marine equipment, food processing, or outdoor machinery. The coarse thread and Class 3A fit enable quick, secure fastening in materials prone to stripping, while the rounded button head offers a low-profile, snag-resistant design for confined spaces. Engineers value its compliance with ASME B18.3 and military standards, ensuring reliability in aerospace, automotive, and heavy machinery applications where failure is not an option.
Specification Summary & Compliance
This screw features a 10-24 UNC coarse thread with Class 3A precision fit for tight tolerances, and is manufactured to meet ASME B18.3, ASTM F879, and MIL-DTL-18240 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
