Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure
- High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing in demanding applications
- Precise alignment and spacing enabled by the 8mm shoulder with tight diameter tolerance (-0.072 to -0.01 mm)
- Secure, tamper-resistant fastening through the hex socket drive requiring only a 3mm hex key
- Consistent thread engagement with Class 5g6g thread fit and coarse 0.7mm pitch for quick assembly and vibration resistance
- Durable performance backed by Rockwell B79 hardness for long-term wear resistance
- Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated use
Professional Applications & Engineering Value
This M4 shoulder screw delivers critical engineering solutions where precise component alignment and corrosion resistance are paramount. Manufactured from 316 Stainless Steel, it excels in marine, chemical processing, and food industry applications where moisture and corrosive agents degrade ordinary fasteners. The 8mm shoulder length with controlled tolerance provides exact positioning for rotating parts, bearings, and linkages, eliminating misalignment and reducing wear. The hex socket drive allows compact installation in confined spaces while the Class 5g6g thread fit ensures consistent clamping force. With 70,000 psi tensile strength, it maintains integrity under dynamic loads, making it ideal for machinery, automation systems, and precision instruments requiring reliable, long-lasting fastening.
Specification Summary & Compliance
This precision shoulder screw features M4 x 0.7mm coarse metric thread with Class 5g6g tolerance for assured fit. The shoulder diameter (6 mm) maintains -0.072 to -0.01 mm tolerance, while shoulder length (8 mm) holds 0 to 0.25 mm tolerance. Manufactured to industrial standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability.
