S-91244A712 1/2"-13 x 1" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance ensures long-lasting performance in harsh chemical or moisture-rich environments without rust or degradation.
• Excellent electrical insulation properties prevent current leakage and short circuits, ideal for electrical assemblies and sensitive electronic applications.
• Wide temperature tolerance from -40° to 185°F maintains structural integrity and functionality in both freezing and elevated temperature conditions.
• Class 2A thread fit with UNC coarse threading provides reliable, easy installation and secure fastening with standard tools, reducing assembly time.
• External hex drive design offers high torque capability and straightforward tool engagement for efficient tightening in confined spaces.
• Lightweight nylon construction reduces overall assembly weight while providing durable, non-conductive, and non-magnetic characteristics.
• RoHS 3 compliance guarantees environmental safety and regulatory adherence for global manufacturing and supply chain requirements.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these nylon plastic hex head screws deliver exceptional value in applications where metal fasteners fail. The off-white nylon material inherently resists corrosion from chemicals, saltwater, and UV exposure, eliminating galvanic corrosion risks in multi-material assemblies. With a fully threaded UNC coarse design and Class 2A thread fit, these screws ensure consistent clamping force and vibration resistance in electrical enclosures, marine equipment, and food processing machinery. The external hex drive allows for high-torque installation using common wrenches, speeding up production lines while the broad temperature range supports use in outdoor or thermally variable environments. Ideal for electrical insulation and non-sparking requirements, they enhance safety in hazardous locations without compromising on durability.

Specification Summary & Compliance

This screw adheres to UNC coarse thread standards with a 1/2"-13 thread size and Class 2A thread fit for precise dimensional accuracy and interchangeability. The fully threaded shank and right-hand thread direction comply with common assembly practices. Manufacturing follows industry norms for hex head screws, featuring a 23/64" head height and 3/4" head width for optimal drive stability. It is fully RoHS 3 (2015/863/EU) Compliant, meeting stringent restrictions on hazardous substances for environmental and health safety in global markets.
