Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. The 316 stainless steel material provides excellent resistance to corrosion and chemicals, making it suitable for demanding environments like food processing, marine, and chemical plants. The 40mm shoulder length acts as a precise datum for locating parts, reducing the need for additional bushings or spacers, which simplifies assembly and lowers costs. The socket head with hex drive allows for compact installation in tight spaces, while the knurled texture enhances handling during manual adjustments. Its metric thread (M6x1) and high tensile strength ensure secure fastening in dynamic applications, from conveyor systems to precision instruments, providing long-term reliability and reduced maintenance.
