S-90269A561 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure
• Enhanced durability and wear resistance from the black oxide finish, providing long-lasting performance in demanding applications
• Precise alignment and smooth rotation ensured by the 100mm shoulder with tight length tolerance (±0.25mm) and standard fit
• High tensile strength of 70,000 psi and minimum shear strength of 35,000 psi for reliable, heavy-duty fastening under stress
• Accurate and secure threading with Class 5g6g metric coarse thread (M5x0.8), reducing the risk of cross-threading and ensuring consistent engagement
• Easy installation and removal using a standard 3mm hex drive socket head, allowing for efficient assembly in confined spaces
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global industrial and electronics markets

Professional Applications & Engineering Value

These M5 shoulder screws are engineered to address critical alignment and durability challenges in precision machinery, automation systems, and assembly jigs. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, which is vital in humid or chemically aggressive settings like marine equipment or food processing plants. Combined with the black oxide finish, the screws reduce friction and prevent galling, extending service life in high-cycle applications. The 100mm shoulder length with minimal tolerance variation provides a stable pivot or spacer, minimizing misalignment in rotating components such as gears, pulleys, or linkages. This design ensures smooth operational performance, reduces maintenance downtime, and supports industrial applications requiring reliable, repeatable fastening solutions.

Specification Summary & Compliance

This shoulder screw features Class 5g6g thread fit per metric standards, ensuring precise thread engagement and interchangeability. The shoulder diameter tolerance is tightly controlled from -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing high dimensional accuracy for engineering assemblies. Manufactured from 316 stainless steel with a black oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, affirming its suitability for regulated industries and environmentally conscious procurement.
