S-90179A836 10-32 x 1 1/2" Thumb Screws

Key Features & Benefits at a Glance

• Effortless manual tightening and loosening with the spade head design, eliminating the need for tools in quick-access applications.
• Enhanced durability and resistance to wear thanks to the steel construction and Rockwell B55 hardness, ensuring long service life in demanding environments.
• Reliable load-bearing capability with a tensile strength of 40,000 psi, providing secure fastening under stress without failure.
• Precise and consistent thread engagement from the Class 2A thread fit and fine thread spacing, reducing the risk of cross-threading and improving assembly efficiency.
• Increased stability and anti-loosening performance due to the integrated flange, which distributes pressure and minimizes surface damage.
• Full thread coverage along the 1 1/2" length for versatile positioning and adjustable clamping in various industrial setups.
• Safe for use in regulated industries as it is RoHS 3 compliant, meeting environmental standards without compromising performance.

Professional Applications & Engineering Value

This 10-32 UNF thumb screw is engineered to address common challenges in industrial settings, such as the need for rapid assembly and disassembly without specialized tools. The spade head offers an ergonomic grip, reducing operator fatigue in high-frequency maintenance tasks, while the steel material and Rockwell B55 hardness ensure it withstands mechanical stress and corrosion in harsh conditions. With a fully threaded design and Class 2A thread fit, it provides precise alignment and vibration resistance, making it ideal for applications in electronics enclosures, machinery panels, and automotive components where fine thread spacing enhances sealing and load distribution. The inclusion of a flange further prevents over-tightening and protects sensitive surfaces, delivering reliable fastening solutions that boost productivity and reduce downtime.
