Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and washdown applications.
- Precise component alignment and pivot points enabled by the 8mm shoulder with tight diameter tolerance, reducing wear on mating parts.
- High-strength fastening with 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance under significant load.
- Secure, non-slip installation provided by the knurled head and 5mm hex socket drive, allowing for high-torque application.
- Wide compatibility and easy assembly with a standard M8x1.25 coarse right-hand thread and Class 5g6g fit for common metric applications.
- Guaranteed dimensional consistency and interchangeability, manufactured in full compliance with the ISO 7379 standard.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to solve critical alignment and rotational challenges in mechanical assemblies. The precision-machined shoulder acts as a built-in spacer or pivot, eliminating the need for separate bushings and reducing assembly complexity. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it a durable choice for food processing, packaging, and automation equipment. The coarse thread pitch ensures rapid installation, while the hex socket drive and knurled head provide a secure grip for high-torque tightening in confined spaces. Its robust construction directly addresses the need for high-strength, long-lasting fasteners in demanding industrial applications.
Specification Summary & Compliance
This shoulder screw features an M8x1.25 coarse metric thread with a Class 5g6g thread fit for standard applications. The shoulder diameter is held to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm. The product is manufactured to meet the dimensional and mechanical specifications of ISO 7379. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
