S-98451A141 M8 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance and electrical conductivity with 360 Brass construction, ideal for harsh environments and electronic assemblies.
• Enhanced durability and load-bearing capacity from Rockwell B55 hardness and 40,000 psi tensile strength, reducing wear and failure risks.
• Accurate alignment and smooth rotation due to the precise 10mm shoulder diameter with tight ±0.025mm tolerance, minimizing part wobble.
• Secure, high-torque installation enabled by the hex socket drive, preventing stripping and ensuring reliable fastening in confined spaces.
• Consistent thread engagement and interchangeability with Class 6g metric coarse threads, speeding up assembly and maintenance.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Optimized for heavy-duty applications with a robust 13mm thread length and coarse 1.25mm pitch, providing strong holding power.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address common industrial challenges like misalignment, corrosion, and assembly inefficiency. The 360 Brass material offers excellent machinability and resistance to rust, making it suitable for precision machinery, automotive components, and electrical enclosures. The hex socket drive allows for easy installation in tight spaces, while the Class 6g thread fit ensures reliable performance in dynamic loads. Its 10mm shoulder diameter with precise tolerances acts as a pivot or spacer, reducing wear on moving parts and extending equipment life. By integrating coarse pitch threads and robust construction, this fastener delivers consistent performance in high-vibration and heavy-duty applications, streamlining maintenance and reducing downtime.

Specification Summary & Compliance

This shoulder screw features a metric M8x1.25mm coarse thread with Class 6g tolerance for precise fit, and a shoulder diameter of 10mm with tolerance of -0.025 to 0 mm for accurate alignment. It complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence in industrial use.
