Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel and black oxide finish, ideal for harsh industrial environments.
- High tensile and shear strength (70,000 psi tensile, 35,000 psi shear) ensures reliable performance under heavy loads.
- Precision thread fit with Class 5g6g tolerance for secure, vibration-resistant fastening in metric assemblies.
- Easy installation and grip thanks to the hex socket drive and knurled head, reducing slippage during tightening.
- Accurate shoulder dimensions with tight tolerances (e.g., shoulder diameter -0.072 to -0.01 mm) for consistent alignment in machinery.
- Durable hardness at Rockwell B79 provides long-lasting wear resistance in repetitive applications.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.
Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address common industrial challenges such as misalignment and corrosion in precision equipment. Made from 316 stainless steel with a black oxide finish, it offers exceptional resistance to chemicals and moisture, making it suitable for automotive, aerospace, and marine applications. The hex socket drive and knurled head facilitate quick assembly in tight spaces, while the coarse metric thread (M4x0.7mm) and Class 5g6g fit ensure stable connections that withstand vibrations and dynamic loads. The precisely machined shoulder (14mm length) acts as a pivot or spacer, reducing wear on components and extending service life in robotic arms, conveyor systems, and electronic enclosures.
Specification Summary & Compliance
This shoulder screw features a metric thread with M4 size, 0.7mm pitch, and Class 5g6g tolerance for high precision. Dimensions include a head diameter of 9mm, shoulder diameter of 5mm (tolerance: -0.072 to -0.01 mm), and shoulder length of 14mm (tolerance: 0 to 0.25 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
