S-93996A726 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant secure fastening with integrated Nylon Patch thread locker, preventing loosening in dynamic applications.
• Superior corrosion resistance from 18-8 Stainless Steel construction, ensuring longevity in harsh industrial environments.
• High-strength performance with a 70,000 psi tensile strength and Rockwell B55 hardness for demanding mechanical assemblies.
• Precise alignment and spacing enabled by the accurately machined 5/8" shoulder with tight diameter and length tolerances.
• Wide operational temperature range from -70° to 250°F, maintaining integrity in extreme conditions.
• Easy installation and removal using a standard 3/32" hex socket drive, reducing assembly time and tooling complexity.
• Reliable thread engagement with Class 2A UNC coarse threads, ensuring consistent fit and reduced cross-threading risk.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical challenges in precision assemblies where alignment, durability, and vibration resistance are paramount. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it ideal for machinery, automotive, and electronic enclosures exposed to moisture or chemicals. The Nylon Patch thread locker secures the fastener against vibrations, eliminating the need for secondary locking devices and reducing maintenance. With a 5/8" shoulder length manufactured to precise tolerances, it acts as a reliable pivot, spacer, or axle in linkages, gears, and rotating mechanisms, ensuring accurate component positioning and smooth operation. The hex socket head allows for high-torque installation in confined spaces, enhancing assembly efficiency for engineers and technicians.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent engagement. The shoulder features a diameter of 3/16" (tolerance: -0.001" to 0") and length of 5/8" (tolerance: 0" to 0.002") for precise assembly. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial use.
