- Enhanced assembly precision due to Class 5g6g thread fit, ensuring reliable mating with components and minimizing play.
- High mechanical strength offering 70,000 psi tensile and 45,000 psi shear strength for demanding applications and extended service life.
- Secure and efficient driving with a knurled hex socket head, providing excellent grip and preventing tool slippage during installation.
- Accurate component alignment via the 50mm shoulder with tight diameter tolerance, functioning as a precise pivot or axle.
- Broad industrial compatibility through compliance with ISO 7379, RoHS 3, and REACH standards, ensuring safety and regulatory acceptance.
- Optimized for coarse threading with 1mm pitch, enabling faster assembly and disassembly in general engineering uses.
Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address common challenges in machinery assembly, such as misalignment and wear. The 18-8 stainless steel material provides excellent corrosion resistance, crucial for operations in moist or chemically aggressive settings, while the Rockwell B83 hardness ensures durability against abrasion. The 50mm shoulder length acts as a stable bearing surface or locator, reducing stress on threads and enhancing pivot accuracy in linkages, gears, and rotating assemblies. Combined with a hex socket drive and knurled head, it offers secure torque transmission and easy handling, streamlining maintenance in automated systems and precision equipment.
Specification Summary & Compliance
The screw features an M6 x 1mm coarse thread with Class 5g6g fit per metric standards, ensuring dimensional accuracy. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for precise fits. It conforms to ISO 7379 manufacturing specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations.
