S-97008A210 10-24 x 1/2" Thumb Screws

Key Features & Benefits at a Glance

• Tool-Free Operation: Spade head design allows for quick manual tightening and loosening, reducing assembly time and eliminating the need for tools in maintenance or adjustments.
• Exceptional Durability: Made from zinc-plated steel with a Rockwell B55 hardness, providing excellent resistance to wear and deformation in demanding industrial environments.
• High Tensile Strength: Withstands up to 40,000 psi, ensuring reliable fastening under stress and preventing failure in heavy-duty applications.
• Secure Flanged Design: Integrated flange increases bearing surface, distributing load more evenly and reducing the risk of surface damage or loosening under vibration.
• Precise Thread Fit: Class 2A thread fit ensures smooth engagement and consistent performance, minimizing cross-threading and ensuring reliable connections.
• Corrosion Resistance: Zinc plating offers a protective barrier against rust and corrosion, extending the screw's service life in various operational conditions.
• Environmental Compliance: RoHS 3 (2015/863/EU) compliant, making it suitable for use in regulated industries and eco-conscious manufacturing processes.

Professional Applications & Engineering Value

This 10-24 UNC thumb screw is engineered to address common challenges in industrial settings where rapid assembly and disassembly are critical. The zinc-plated steel construction, combined with a Rockwell B55 hardness and 40,000 psi tensile strength, ensures it can handle repetitive use without stripping or breaking. The spade head design enables easy manual operation, ideal for applications in machinery access panels, electronic enclosures, and prototyping where tools may not be readily available. Its coarse thread spacing and fully threaded body provide quick engagement and strong holding power, while the flanged feature prevents over-tightening and protects sensitive surfaces. This makes it a reliable choice for maintenance-heavy environments, reducing downtime and improving operational efficiency.

Specification Summary & Compliance

This thumb screw adheres to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy and smooth installation. It features a right-hand thread direction and coarse thread spacing, ensuring compatibility with standard industrial components. Manufactured in compliance with RoHS 3 (2015/863/EU) regulations, it meets environmental safety requirements for hazardous substance restrictions, making it suitable for global supply chains and regulated industries.
