S-93897A694 3/8"-16 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-resistant Nylon 6/6 construction eliminates rust and galvanic corrosion in harsh environments, extending service life
• Excellent electrical insulation properties prevent current conduction, enhancing safety in electrical assemblies
• Wide operating temperature range (-40° to 185° F) ensures reliable performance in both freezing and elevated temperature conditions
• Precision Class 2A thread fit provides consistent, secure fastening with reduced risk of cross-threading during installation
• 1 1/4" shoulder length with tight tolerances offers precise component alignment and acts as a reliable bearing surface
• 1/4" hex socket drive allows for high-torque installation in confined spaces with standard tools
• RoHS 3 compliance meets international environmental standards for restricted substances

Professional Applications & Engineering Value

This Nylon 6/6 plastic shoulder screw delivers critical engineering advantages where metal fasteners fail. The 3/8"-16 UNC coarse threading with Class 2A fit ensures rapid assembly with vibration resistance, while the smooth socket head design accommodates high-torque applications. The precisely machined 1 1/4" shoulder serves as an axle or pivot point in machinery, providing exact component spacing without additional bushings. Ideal for electrical insulating applications, conveyor systems, and food processing equipment, this corrosion-resistant shoulder screw eliminates conductivity concerns and withstands temperature fluctuations from -40° to 185°F without degradation.

Specification Summary & Compliance

Manufactured to inch system standards with Class 2A thread fit and UNC coarse threading. Features a shoulder diameter of 1/2" with tolerance of -0.012" to -0.002" and shoulder length of 1 1/4" with tolerance of -0.015" to 0.015". This socket head shoulder screw is RoHS 3 (2015/863/EU) Compliant and meets standard manufacturing specifications for plastic fasteners.
