Key Features & Benefits at a Glance
- Superior corrosion resistance with 360 Brass construction, ideal for harsh environments and electrical applications
- Precise alignment and pivot functions enabled by the accurately machined 6mm shoulder with tight diameter tolerance
- High mechanical strength offering 40,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance
- Easy installation and removal with the hex socket drive, reducing tool slippage and assembly time
- Consistent thread engagement ensured by Class 6g thread fit, minimizing the risk of cross-threading in automated assembly
- Broad industrial compliance meeting RoHS 3 and REACH standards for safe use in regulated markets
- Durable coarse threading (M5x0.8) providing robust fastening in high-vibration applications
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 360 Brass material offers excellent machinability and natural corrosion resistance, making it suitable for marine, electrical, and food-grade equipment where stainless steel may cause galvanic issues. The 10mm shoulder length with precise tolerances acts as a reliable pivot or spacer in rotating mechanisms, reducing bushing wear and maintaining component alignment. With its socket head hex drive and Class 6g thread fit, it ensures secure fastening in automated production lines, while the coarse metric thread enhances durability in high-vibration environments like machinery and automotive subsystems.
Specification Summary & Compliance
This shoulder screw conforms to Metric system standards with M5x0.8 coarse threads and Class 6g thread fit for consistent performance. The shoulder features a diameter of 6mm with tolerance of -0.025 to 0 mm and length of 10mm with tolerance of 0 to 0.05 mm, ensuring precise assembly. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) standards, confirming its suitability for industrial and consumer applications.
