S-93939A712 2-56 x 1" Plastic Fillister Head Slotted Screws

Key Features & Benefits at a Glance

• Non-conductive and corrosion-resistant nylon plastic ensures reliable performance in electrical and chemical environments without risk of short circuits or rust.
• High-profile fillister head with slotted drive provides enhanced grip and easier installation with standard tools, reducing assembly time.
• Class 2A thread fit with coarse UNC threading delivers consistent engagement and quick assembly in various materials, minimizing cross-threading risks.
• Wide temperature resistance from -40°F to 185°F maintains structural integrity in fluctuating thermal conditions, ideal for outdoor or HVAC applications.
• RoHS 3 (2015/863/EU) compliance guarantees environmentally safe use, meeting strict regulatory standards for hazardous substance restrictions.
• Fully threaded 1" length design offers maximum holding power and adjustability across the entire shank for secure fastening.
• Lightweight and durable nylon construction reduces overall component weight while resisting wear, vibration, and impact in industrial settings.

Professional Applications & Engineering Value

This 2-56 UNC nylon plastic screw with a fillister head and slotted drive addresses critical needs in electrical enclosures, automotive assemblies, and consumer electronics where metal fasteners pose conductivity or corrosion risks. The nylon material inherently resists moisture, chemicals, and electrical currents, preventing galvanic corrosion and ensuring insulation. Its coarse thread spacing and Class 2A fit enable rapid installation in plastics and soft metals, reducing labor costs and improving production efficiency. Engineers value the high-profile rounded head for its low protrusion and secure seating, which minimizes snagging in compact designs while providing reliable torque transmission. Ideal for temperature-sensitive environments, it maintains performance from sub-zero to moderate heat, supporting applications in industrial machinery, packaging equipment, and marine components without degradation.
