S-91244A620 3/8"-16 x 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance ensures long-lasting performance in harsh or chemically active environments without rust or degradation.
• Excellent electrical insulation properties prevent electrical conductivity, making them ideal for electronic assemblies and sensitive equipment.
• Wide operating temperature range from -40° to 185°F maintains integrity and function in both freezing and moderately high-heat conditions.
• Class 2A coarse thread fit provides reliable, easy engagement and reduces cross-threading risks during high-speed assembly.
• External hex drive design allows for quick installation and removal with standard tools, boosting assembly line efficiency.
• RoHS 3 compliance guarantees environmental safety and meets stringent international regulations for hazardous substances.
• Lightweight and non-magnetic nylon construction reduces overall weight and avoids interference in magnetic-sensitive applications.

Professional Applications & Engineering Value

Engineered for demanding settings, these 3/8"-16 UNC nylon hex head screws deliver critical advantages where metal fasteners fall short. The off-white nylon plastic material inherently resists corrosion from moisture, chemicals, and salts, eliminating the need for additional coatings. This makes them a top choice for electrical enclosures, marine hardware, and food processing equipment. The fully threaded coarse UNC design ensures strong holding power across the entire length, while the external hex drive supports rapid torque application with common wrenches. By providing reliable electrical insulation and stability across a -40° to 185°F temperature range, these screws prevent short circuits and thermal failure, enhancing safety and durability in industrial assemblies.

Specification Summary & Compliance

This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent, precision threading. Dimensions include a 3/8"-16 thread size, 1/2" length, and 9/16" head width for secure fastening. It is manufactured in accordance with industry practices for inch system measurements and is RoHS 3 (2015/863/EU) Compliant, ensuring it is free from restricted hazardous substances and suitable for global supply chains.
