S-94613A533 1/4"-20 x 1/4" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant nylon construction ensures long-lasting performance in humid or chemically exposed environments without rust or degradation.
• Electrical insulation properties prevent current conduction, making them ideal for safe use in electrical assemblies and sensitive electronic equipment.
• Wide temperature tolerance from -40° to 185°F maintains structural integrity and dimensional stability in both freezing and moderately high-heat conditions.
• External hex drive and hex head design allows for quick, secure installation with standard wrenches, reducing assembly time and improving torque application.
• Class 2A thread fit with UNC coarse threading provides reliable engagement and easy alignment, minimizing cross-threading risks in repetitive industrial use.
• RoHS 3 (2015/863/EU) compliance guarantees adherence to environmental safety standards, supporting sustainable and eco-conscious manufacturing practices.
• Lightweight off-white nylon material offers non-magnetic, non-conductive advantages while blending discreetly in finished product designs.

Professional Applications & Engineering Value

Engineered for demanding electrical and industrial applications, these 1/4"-20 UNC nylon hex head screws address critical challenges like galvanic corrosion, electrical short circuits, and weight reduction. The nylon plastic construction inherently resists moisture, chemicals, and UV exposure, eliminating the need for additional protective coatings. With a fully threaded design and coarse thread spacing, they deliver superior holding power in plastic, composite, or soft metal substrates, reducing vibration-induced loosening. The external hex drive ensures high torque transmission without stripping, streamlining maintenance in confined spaces. Ideal for panel fastening, enclosure assembly, and marine equipment, these screws combine temperature resistance with electrical insulation to enhance safety and durability in sensitive operational environments.

Specification Summary & Compliance

These screws adhere to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy and interchangeability. The 1/4"-20 thread size and coarse thread spacing comply with unified screw thread specifications, ensuring reliable performance in general-purpose assemblies. Manufacturing follows industry guidelines for nylon plastic fasteners, with full compliance to RoHS 3 (2015/863/EU) regulations, confirming the absence of restricted hazardous substances. Suitable for use within a temperature range of -40° to 185°F, they meet functional demands without compromising material properties or thread integrity.
