S-96654A139 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Nylon patch thread locker maintains secure fastening in temperatures from -70° to 250°F, preventing loosening in dynamic industrial environments.
• Corrosion-resistant durability: 18-8 stainless steel construction with passivated finish ensures long-term reliability in harsh or moist conditions.
• Precise component alignment: 10mm shoulder with tight diameter tolerance provides accurate positioning for rotating parts and assemblies.
• High-strength performance: 70,000 psi tensile strength and Rockwell B55 hardness withstand heavy loads and repeated use.
• Efficient torque transmission: Hex socket head with 3mm drive allows for high-torque installation without stripping.
• Standardized compatibility: Metric M5x0.8mm coarse thread with Class 6g fit ensures interchangeability with existing metric components.
• Environmental compliance: Meets RoHS 3 and REACH regulations for safe use in regulated industries.

Professional Applications & Engineering Value

This precision shoulder screw solves critical alignment and vibration challenges in mechanical assemblies. The 10mm shoulder length with precise diameter control acts as a pivot or bearing surface, eliminating the need for additional spacers in machinery, automotive, and electronics applications. Made from 18-8 stainless steel with a passivated finish, it resists corrosion while the nylon patch thread locking technology secures joints against shock and vibration. The hex socket head design enables flush mounting and high torque application in confined spaces, making it ideal for industrial fasteners requiring both precision and reliability under thermal stress from -70° to 250°F.

Specification Summary & Compliance

This M5 shoulder screw features a 6mm thread length with Class 6g thread fit per metric standards, ensuring consistent engagement. The shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm provide precise assembly control. Manufactured to industrial fastener specifications, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for global supply chains.
