S-91970A620 3/8"-16 x 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance for long-lasting performance in harsh environments like marine or chemical settings, eliminating rust issues common with metal fasteners.
• Superior electrical insulation properties prevent electrical conductivity, making them ideal for safe use in electrical assemblies and sensitive electronic equipment.
• Wide temperature tolerance from -40°F to 185°F ensures reliable operation in both freezing and moderately high-temperature conditions without degradation.
• Class 2A thread fit provides consistent, reliable engagement for easy installation and secure fastening in various industrial applications.
• External hex drive design allows for straightforward installation with standard tools, reducing assembly time and improving efficiency.
• RoHS 3 compliance guarantees environmental safety and adherence to strict regulatory standards for hazardous substance restrictions.
• Lightweight and durable nylon construction offers high strength-to-weight ratio, reducing overall assembly weight while maintaining integrity.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 3/8"-16 UNC nylon hex head screws solve critical challenges where metal fasteners fail. The nylon plastic material inherently resists corrosion from moisture, chemicals, and saltwater, making them perfect for marine applications and chemical-resistant assemblies. Their non-conductive properties prevent electrical shorts, ideal for electrical enclosures, control panels, and sensitive devices. With a coarse thread and fully threaded design, they ensure quick, secure fastening in plastics and soft materials, reducing stripping risks. This combination of durability and insulation extends equipment lifespan and enhances safety in B2B procurement for OEMs and maintenance teams.

Specification Summary & Compliance
