S-94690A717 4-40 x 9/32" Plastic Binding Head Slotted Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to nylon plastic construction, ideal for humid or chemically exposed environments without rust or degradation.
• Secure and reliable fastening with Class 2A thread fit, ensuring consistent engagement and reducing the risk of loosening in vibration-prone applications.
• Wide binding head design provides a larger bearing surface for enhanced load distribution and prevents pull-through in softer materials.
• Broad temperature tolerance from -40° to 185°F, maintaining integrity and performance in varied operating conditions.
• RoHS 3 compliance guarantees environmental safety and meets stringent regulatory standards for electronic and consumer goods.
• Slotted drive convenience allows for easy installation and removal with standard screwdrivers, simplifying assembly processes.
• Fully threaded shank offers maximum grip length and adjustability for precise fastening in diverse material thicknesses.

Professional Applications & Engineering Value

This 4-40 UNC coarse thread nylon plastic rounded head screw is engineered to address common industrial challenges, such as galvanic corrosion in mixed-material assemblies and electrical insulation requirements. The nylon material provides inherent non-conductivity, making it perfect for electrical applications where metal fasteners could cause short circuits. Its wide binding head profile and coarse threading ensure quick installation and strong holding power in plastics, wood, or soft metals, reducing assembly time and improving reliability. With a temperature range of -40° to 185°F, it performs consistently in both cold storage and moderate heat environments, offering a durable, lightweight alternative to metal screws that won't corrode or conduct electricity.

Specification Summary & Compliance

This screw adheres to UNC coarse thread standards with a Class 2A thread fit for precise dimensional accuracy and smooth assembly. It is manufactured in the inch system with a length of 9/32" and is fully threaded for optimal performance. Compliance includes RoHS 3 (2015/863/EU), ensuring it is free from hazardous substances and suitable for global markets requiring environmental and safety regulations.
