S-93897A708 3/8"-16 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-free operation with Nylon 6/6 plastic construction, ideal for harsh or chemical environments where metal fasteners would degrade.
• Precise component alignment ensured by the 1 3/4" shoulder length with tight tolerances, providing a stable pivot or spacer in assemblies.
• High-strength engagement from the 3/8"-16 UNC coarse thread with Class 2A fit, offering reliable fastening and easy assembly.
• Broad temperature resilience from -40° to 185° F, maintaining integrity and performance in varied operating conditions.
• Secure, flush installation with the smooth socket head and 1/4" hex drive, allowing for high torque application and a clean finish.
• Environmental regulation compliance with RoHS 3, ensuring the screw is free from hazardous substances for global industrial use.
• Reduced part wear and noise due to the self-lubricating nature of Nylon, extending the life of mating components.

Professional Applications & Engineering Value

This Nylon 6/6 Plastic Shoulder Screw is engineered to solve critical challenges in precision assemblies. The 1 3/4" shoulder length with minimal tolerance provides an exact datum for rotating parts like gears, bearings, and linkages, eliminating misalignment and reducing wear. Made from Nylon 6/6, it offers excellent electrical insulation and resistance to many chemicals, making it superior to metal in corrosive or non-conductive applications. The 3/8"-16 UNC coarse thread with a Class 2A fit ensures quick and secure fastening, while the smooth socket head design allows for a streamlined profile. Ideal for use in machinery, electronics, and automotive subsystems, this screw delivers reliable performance where thermal stability (from -40° to 185°F) and regulatory compliance are paramount.
