S-98256A204 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior strength-to-weight ratio from Grade 2 Titanium construction, providing 40,000 psi tensile strength for demanding applications without adding bulk.
• Precise component alignment ensured by the 3/16" shoulder with tight diameter and length tolerances, minimizing assembly play and vibration.
• Reliable, vibration-resistant thread engagement with Class 3A UNC coarse threads, offering superior fit and holding power in high-stress environments.
• Easy installation and high-torque capability via the 3/32" hex socket drive and knurled head, preventing tool slippage and speeding up assembly.
• Excellent corrosion resistance and durability inherent to titanium, coupled with a Rockwell B80 hardness for long service life in harsh conditions.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring suitability for global industrial supply chains.
• Versatile right-hand UNC thread design for broad compatibility with standard components and simplified sourcing.

Professional Applications & Engineering Value

This Grade 2 Titanium Shoulder Screw is engineered to solve critical alignment and strength challenges in precision assemblies. The 3/16" shoulder length with controlled tolerances acts as a precise pivot or spacer, eliminating misalignment in machinery, robotics, and aerospace components. The UNC coarse thread and Class 3A fit provide robust, vibration-resistant fastening, crucial for dynamic loads. The socket head with hex drive allows for compact installation in confined spaces, while the knurled texture enhances grip during manual adjustments. Made from titanium, it resists corrosion and reduces weight without sacrificing the 40,000 psi tensile strength, making it ideal for applications where both performance and regulatory compliance (RoHS 3, REACH) are mandatory.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precision. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for exacting dimensional control. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted substances for industrial and international use.
