Key Features & Benefits at a Glance
- Vibration-resistant locking: Integrated nylon patch thread locker maintains secure fastening in dynamic applications from -70° to 250°F
- Exceptional corrosion resistance: 18-8 stainless steel construction with passivated finish provides superior protection against rust and chemical exposure
- Precision alignment: 4mm shoulder diameter with tight tolerance ensures accurate component positioning and reduces wear
- High-strength performance: 70,000 psi tensile strength and Rockwell B55 hardness withstand heavy loads and repeated use
- Reliable thread engagement: Class 6g thread fit with M3x0.5mm coarse spacing ensures consistent, secure mating with components
- Easy installation in confined spaces: Hex socket drive with 2mm key size allows efficient tightening even in limited access areas
- Industry compliance ready: Meets RoHS 3 and REACH environmental standards for global manufacturing applications
Professional Applications & Engineering Value
This precision M3 shoulder screw with 25mm shoulder length delivers critical engineering solutions for industrial applications requiring exact component alignment and vibration resistance. The 18-8 stainless steel construction combined with passivated finish ensures long-term reliability in harsh environments, while the integrated nylon patch thread locker prevents loosening under dynamic loads. The hex socket drive enables secure installation in confined spaces common in machinery, automation systems, and precision instruments. With Class 6g thread fit and precise shoulder tolerances, this fastener eliminates play between components, reducing wear and maintaining alignment in rotating assemblies, pivot points, and guide mechanisms where dimensional stability is paramount.
Specification Summary & Compliance
This metric shoulder screw features M3x0.5mm coarse threads with Class 6g thread fit tolerance, 4mm shoulder diameter with -0.025 to 0 mm tolerance, and 25mm shoulder length with 0 to 0.05 mm tolerance. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
