S-98945A041 3/8"-16 Flange Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from fiberglass construction, ideal for harsh environments like marine and chemical processing.
• Excellent electrical insulation prevents current conduction, enhancing safety in electrical assemblies and sensitive equipment.
• Reliable coarse thread engagement with UNC 3/8"-16 and Class 2B fit ensures quick assembly and vibration resistance.
• Integrated flange design with 3/4" diameter distributes load, eliminating the need for a separate washer and speeding up installation.
• Durable external hex drive provides secure tool grip for high-torque applications and easy maintenance.
• RoHS 3 compliance guarantees environmental safety and meets global regulatory standards for hazardous substances.
• Lightweight yet strong fiberglass material reduces overall weight without compromising on mechanical integrity.

Professional Applications & Engineering Value

This fiberglass flange nut is engineered to address critical challenges in demanding sectors. Its non-conductive properties make it indispensable for electrical enclosures, power distribution systems, and telecommunications, where stray currents can cause failures. In marine and chemical applications, the inherent corrosion resistance of fiberglass withstands saltwater, acids, and alkalis, prolonging service life and reducing maintenance costs. The UNC coarse thread and Class 2B fit facilitate rapid installation in high-volume production lines, while the integrated flange enhances joint stability by increasing the bearing surface. By combining electrical insulation with mechanical durability, this nut delivers a cost-effective fastening solution that minimizes downtime and ensures operational safety in corrosive or electrically sensitive environments.
