S-90270A681 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
• Precise component alignment and location ensured by the smooth, 20mm long shoulder with a precise fit, reducing assembly errors.
• High mechanical strength and durability from a Rockwell B55 hardness and 70,000 psi tensile strength, preventing failure under load.
• Secure and reliable fastening with a Class 6g metric coarse thread (M5x0.8), providing excellent grip and vibration resistance.
• Efficient installation and removal using the standard socket head, allowing for high torque application in confined spaces.
• Guaranteed material safety and compliance by meeting RoHS 3 and REACH regulations, ensuring suitability for sensitive industries.
• Consistent dimensional accuracy with tight shoulder diameter and length tolerances, enabling repeatable and predictable performance.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial assemblies. The M5x0.8 coarse thread and 20mm shoulder length work in tandem to securely fasten components while the unthreaded shoulder acts as a precise bearing surface or pivot, eliminating the need for separate spacers or bushings. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it a reliable choice for machinery, automotive sub-assemblies, and electronic enclosures exposed to demanding conditions. The socket head design facilitates a clean installation with a flush finish, which is crucial for applications where protruding hardware is not an option.

Specification Summary & Compliance

This M5 shoulder screw features a Metric M5x0.8 thread with a Class 6g tolerance for a reliable fit. The shoulder diameter is 6 mm with a tolerance of -0.025 to 0 mm, and the shoulder length is 20 mm with a tolerance of 0 to 0.05 mm, ensuring precise fit and alignment. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
