S-90265A179 M2 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
• High tensile and shear strength (70,000 psi tensile, 45,000 psi shear) for reliable load-bearing in demanding applications.
• Precise thread fit with Class 5g6g tolerance, enabling smooth assembly and secure fastening without play.
• Enhanced grip and torque application from the knurled socket head and 2 mm hex drive, reducing slippage during installation.
• Accurate shoulder dimensions (4 mm diameter, 6 mm length) for consistent alignment and spacing in mechanical assemblies.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and regulatory adherence.
• Durable material hardness (Rockwell B83) that resists wear and deformation under repeated use.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and component wear. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it ideal for electronics, automotive, and machinery where exposure to moisture or chemicals is a concern. The coarse pitch thread (0.4 mm) and Class 5g6g thread fit ensure quick, secure fastening with minimal risk of cross-threading. The knurled socket head with a 2 mm hex drive provides superior torque transfer, reducing tool slippage and damage in tight spaces. With a 4 mm shoulder diameter and 6 mm shoulder length, it serves as a reliable spacer or pivot in applications like rotating shafts and precision instruments, enhancing durability and reducing maintenance needs.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with precise thread dimensions including M2 x 0.4 mm coarse pitch and Class 5g6g thread fit. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally safe and regulated industrial use.
