S-93897A701 3/8"-16 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-resistant Nylon 6/6 construction ensures reliable performance in humid or chemically aggressive environments without rust or galvanic corrosion.
• Precision 1 1/2" shoulder length with tight tolerances provides accurate alignment and spacing for rotating components like gears and pulleys.
• Wide operating temperature range (-40° to 185° F) maintains structural integrity and dimensional stability across diverse industrial conditions.
• Smooth socket head with 1/4" hex drive allows for clean installation and high torque application without marring surfaces.
• Class 2A thread fit with 3/8"-16 UNC coarse threads delivers secure fastening and easy assembly in plastic or soft material applications.
• RoHS 3 compliance meets international environmental standards for hazardous substance restriction in electronic and consumer products.
• Non-conductive and lightweight properties prevent electrical shorts and reduce overall assembly weight in sensitive equipment.

Professional Applications & Engineering Value

Engineered for precision motion control and alignment, this Nylon 6/6 plastic shoulder screw solves critical challenges in assemblies requiring electrical insulation, corrosion resistance, and weight reduction. The 1 1/2" shoulder length with standard fit acts as a precise axle or pivot point in conveyor systems, packaging machinery, and automotive components, eliminating the need for additional bushings. Its 3/8"-16 UNC coarse threads and smooth socket head withstand vibrational forces while preventing galvanic corrosion in mixed-material assemblies. Ideal for electrical enclosures, food processing equipment, and marine applications where metal fasteners would cause contamination or degradation.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit per UNC standards with shoulder diameter tolerance of -0.012" to -0.002" and shoulder length tolerance of -0.015" to 0.015". Manufacturing follows inch system specifications for right-hand UNC threads and standard shoulder profile. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for applications requiring hazardous substance restriction compliance.
