S-91244A628 3/8"-16 x 1 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance eliminates rust concerns in humid or chemical environments, reducing maintenance costs
• Excellent electrical insulation properties prevent current leakage and short circuits in electrical assemblies
• Wide temperature tolerance from -40° to 185°F maintains structural integrity in varying operational conditions
• External hex drive design provides secure tool engagement for efficient installation with standard wrenches
• Class 2A thread fit ensures consistent mating with nuts and threaded components for reliable fastening
• RoHS 3 compliance meets environmental regulations for hazardous substance restrictions in industrial applications
• Partially threaded shank allows precise clamping force control where full threading isn't required

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this 3/8"-16 UNC nylon plastic hex head screw solves critical challenges in electrical, marine, and chemical processing applications. The nylon construction provides inherent corrosion resistance where metal fasteners would deteriorate, while the electrical insulation properties make it ideal for electrical enclosures, control panels, and electronic assemblies. The coarse UNC thread and external hex drive design enable quick installation and removal in maintenance-heavy environments. With operational capability from -40° to 185°F, this fastener maintains performance in both freezing conditions and elevated temperature applications, offering a durable alternative to metallic options where conductivity or corrosion presents engineering challenges.

Specification Summary & Compliance

This inch system fastener features 3/8"-16 UNC coarse threads with Class 2A thread fit tolerance for consistent mating performance. The partially threaded design provides a 1" minimum thread length on the 1½" overall length body. Manufactured to meet RoHS 3 (2015/863/EU) compliance standards, this screw contains no restricted hazardous substances, making it suitable for global industrial applications requiring environmental regulation adherence.
