S-90387A337 1/4"-20 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced Durability & Strength: Glass-filled nylon construction provides superior mechanical strength compared to standard plastic nuts, resisting cracking and deformation under load.
• Wide Temperature Resilience: Maintains integrity and performance in environments ranging from -20° to 230° F, ideal for applications with thermal cycling.
• Superior Corrosion & Chemical Resistance: Inherently resistant to rust, galvanic corrosion, and many chemicals, eliminating the need for protective coatings and reducing long-term maintenance.
• Reliable Thread Engagement: Precision-molded UNC coarse threads with a Class 2B fit ensure easy, consistent installation and a secure, vibration-resistant hold.
• Lightweight & Non-Conductive: Plastic material reduces overall assembly weight and provides excellent electrical insulation for sensitive electronic or electrical applications.
• Standard External Hex Drive: Familiar standard hex profile allows for quick installation and removal using common wrenches and sockets, streamlining assembly processes.
• Global Compliance & Safety: Conforms to RoHS 3 and REACH environmental regulations, ensuring safe use in regulated markets and sustainable manufacturing practices.

Professional Applications & Engineering Value

This glass-filled nylon hex nut is engineered to solve critical challenges in corrosive, electrically sensitive, or weight-conscious industrial environments. Its 1/4"-20 UNC coarse thread and Class 2B fit provide reliable fastening in assemblies where metal corrosion is a primary concern, such as in marine hardware, chemical processing equipment, and outdoor enclosures. The glass-filled nylon material offers a unique combination of high tensile strength and temperature resistance, making it a robust alternative to metal in applications requiring thermal stability from -20° to 230° F. Its off-white color and plastic composition are ideal for consumer appliances, automotive components, and electronics, where non-conductivity and aesthetic consistency are vital. By specifying this nut, engineers effectively eliminate galvanic corrosion risks, reduce part weight, and ensure long-term reliability without sacrificing performance.

Specification Summary & Compliance

This nut features a 1/4"-20 UNC coarse thread with a standard Class 2B thread fit for consistent engagement. The external hex drive has a standard profile with a width of 7/16" and a height of 15/64". It is manufactured from high-grade glass-filled nylon plastic and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety standards for industrial components.
