S-94690A707 2-56 x 1/4" Plastic Binding Head Slotted Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to nylon plastic construction, eliminating rust and galvanic compatibility issues in harsh environments.
• Superior electrical insulation properties for safe use in electrical assemblies and sensitive electronic applications.
• Wide rounded binding head design provides a larger bearing surface for secure fastening and reduced risk of material damage.
• Reliable performance across a broad temperature range from -40°F to 185°F, ensuring stability in various operating conditions.
• Coarse UNC threads with Class 2A fit offer easier, faster assembly and reduced cross-threading risk compared to fine threads.
• Fully threaded shank maximizes grip and holding power along the entire length for a more secure connection.
• Compliance with RoHS 3 (2015/863/EU) ensures the product meets stringent environmental and safety standards for global use.

Professional Applications & Engineering Value

Engineered for precision and durability, this 2-56 UNC nylon plastic screw with a wide rounded binding head and slotted drive is ideal for applications requiring non-conductive, lightweight, and corrosion-resistant fastening. The nylon material provides excellent dielectric strength, making it perfect for electrical enclosures, PCB mounting, and consumer electronics where electrical isolation is critical. Its coarse thread and Class 2A thread fit ensure quick, reliable installation in plastic or soft metal components, reducing assembly time and minimizing thread stripping. The temperature resistance from -40°F to 185°F allows consistent performance in both indoor and outdoor environments, addressing common issues like thermal expansion and chemical degradation. These features make it a top choice for industries such as automotive, telecommunications, and appliance manufacturing, where reliability and regulatory compliance are paramount.

Specification Summary & Compliance

This screw adheres to UNC (Unified Coarse) thread standards with a Class 2A thread fit for consistent dimensional accuracy and ease of assembly. Manufactured in the inch system, it features a 2-56 thread size, 1/4" length, and is fully threaded for maximum engagement. The product is RoHS 3 (2015/863/EU) compliant, confirming it is free of hazardous substances and suitable for use in regulated markets. No specific hardness rating is provided, as it is typical for non-metallic fasteners where mechanical properties are derived from the nylon material's inherent characteristics.
