S-91970A716 1/2"-13 x 1 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-free performance with durable Nylon Plastic construction, ideal for harsh environments where metal fasteners would degrade
• Secure and reliable fastening with Class 2A thread fit, ensuring consistent engagement and reducing the risk of loosening under vibration
• Easy installation and removal using standard 3/4" external hex drive, compatible with common wrenches for efficient assembly
• Versatile temperature resistance from -40° to 185°F, maintaining integrity in both freezing and moderately high-heat applications
• Reduced part weight and electrical insulation due to nylon material, perfect for applications requiring non-conductive or lightweight components
• Optimized grip and alignment with partially threaded design, providing enhanced clamping force on specific joint sections
• Environmentally compliant and safe for regulated industries, meeting RoHS 3 standards for hazardous substance restrictions

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these 1/2"-13 UNC coarse thread hex head screws solve critical challenges in assembly and maintenance. The Nylon Plastic material offers inherent resistance to chemicals, moisture, and corrosion, eliminating galvanic issues when used with dissimilar metals. This makes them ideal for electrical enclosures, marine equipment, and food processing machinery where non-conductive and non-corrosive properties are essential. The coarse thread design ensures quick installation and robust holding power in softer materials or plastics, while the partially threaded shank concentrates clamping force precisely. With a broad temperature range from -40° to 185°F, these screws perform reliably in outdoor, automotive, and HVAC applications, providing long-term durability without the need for protective coatings.
