S-93897A686 3/8"-16 Shoulder Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to Nylon 6/6 material, ideal for harsh or wash-down environments.
• Electrical insulation properties prevent current conduction, enhancing safety in electrical assemblies.
• Wide temperature tolerance from -40° to 185° F ensures reliable performance in varied operating conditions.
• Precise Class 2A thread fit and UNC coarse threading provide smooth assembly and secure fastening.
• 1/4" hex drive socket head allows for high-torque installation with standard tools, reducing slippage.
• 1" shoulder length with controlled tolerances acts as a reliable spacer or pivot in mechanical designs.
• RoHS 3 compliance meets environmental regulations, supporting sustainable manufacturing practices.

Professional Applications & Engineering Value

This Nylon 6/6 Plastic Shoulder Screw is engineered to solve common industrial challenges such as galvanic corrosion, electrical isolation, and weight reduction. The 3/8"-16 UNC coarse thread ensures quick and secure engagement, while the smooth socket head with a 1/4" hex drive facilitates easy installation in confined spaces. Its 1" shoulder length provides a precise bearing surface for rotating components like gears and pulleys, reducing wear and maintaining alignment. Ideal for applications in electronics, food processing, and automotive sectors, this screw offers a non-conductive, temperature-resistant alternative to metal fasteners, ensuring long-term reliability without compromising performance.

Specification Summary & Compliance
