S-93985A531 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced durability and corrosion resistance with 416 Stainless Steel construction and Rockwell C26 hardness, ensuring long service life in harsh industrial environments.
• Precise alignment and secure component positioning thanks to the 1/4" shoulder diameter with tight tolerances (±0.001") and precise shoulder fit.
• High tensile strength of 120,000 psi provides reliable fastening under heavy loads, reducing the risk of mechanical failure.
• Fine UNF threads (10-32) with Class 2A fit offer superior vibration resistance and secure engagement in precision assemblies.
• Easy installation and removal with a standard hex drive (1/8"), allowing for efficient maintenance and assembly in confined spaces.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and suitability for global markets and sensitive applications.
• Smooth head texture and standard socket profile minimize galling and provide a clean, professional finish for high-visibility uses.

Professional Applications & Engineering Value

These 10-32 UNF shoulder screws are engineered to address critical challenges in precision machinery, such as misalignment and component wear. The 416 Stainless Steel material, combined with a Rockwell C26 hardness, offers excellent resistance to corrosion and abrasion, making them ideal for industrial applications like robotics, automotive assemblies, and electronic enclosures. The fine thread design and Class 2A fit ensure stable performance in high-vibration environments, while the 1/4" shoulder diameter with tight tolerances provides accurate pivoting and alignment. This reduces assembly time and maintenance costs, delivering reliable engineering value in demanding settings where precision and durability are paramount.
