S-96654A146 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Secure vibration-resistant fastening with an integrated nylon patch thread locker that maintains integrity from -70° to 250°F, reducing maintenance and loosening in dynamic environments.
• Exceptional corrosion resistance due to 18-8 stainless steel and passivated finish, ensuring long-term reliability in harsh or humid industrial settings.
• Precise alignment and smooth rotation with a 30mm shoulder length and tight diameter tolerance, minimizing wear and enabling accurate component positioning.
• High-strength performance offering 70,000 psi tensile strength and Rockwell B55 hardness for dependable use in heavy-duty and high-stress applications.
• Easy installation and removal with a hex socket head design, allowing efficient torque application in confined spaces without stripping.
• Reliable thread engagement through Class 6g metric coarse threads (M5x0.8mm), ensuring consistent fit and reducing cross-threading risks.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making it suitable for regulated industries and global supply chains.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges such as misalignment, vibration-induced failure, and corrosion. The 18-8 stainless steel construction, combined with a passivated finish, provides superior resistance to rust and chemicals, extending service life in demanding environments like machinery, automotive assemblies, and electronic enclosures. The integrated nylon patch thread locker secures the fastener against loosening under dynamic loads, reducing downtime for re-tightening. With a precise shoulder fit and 30mm shoulder length, it ensures accurate alignment of moving parts—such as in bearings, pulleys, or linkages—minimizing friction and wear. The hex socket head allows for easy access in tight spaces, streamlining maintenance and assembly processes while supporting high tensile strength requirements.

Specification Summary & Compliance

This shoulder screw features a Class 6g thread fit for metric coarse threads (M5x0.8mm), with a shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm, ensuring precise dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for industrial applications with strict environmental and safety standards.
