S-90179A827 10-32 x 3/8" Thumb Screws

Key Features & Benefits at a Glance

• Effortless hand-tightening with a spade head design that provides superior grip and torque without tools, reducing assembly time in maintenance and prototyping.
• Enhanced durability and wear resistance thanks to Rockwell B55 hardness, ensuring the screw maintains its integrity under repeated use in industrial environments.
• High tensile strength of 40,000 psi delivers reliable clamping force and resistance to loosening in vibration-prone applications.
• Flanged design increases bearing surface area, distributing load evenly and preventing damage to softer materials.
• Fully threaded shank allows for maximum adjustability and secure fastening along the entire 3/8" length.
• Precise Class 2A thread fit ensures smooth engagement and consistent performance with standard UNF nuts and tapped holes.
• Right-hand fine thread (10-32 UNF) offers excellent holding power and is ideal for applications requiring fine adjustment and secure fastening.

Professional Applications & Engineering Value

This 10-32 UNF steel thumb screw is engineered to address common challenges in industrial settings, such as the need for quick, tool-free adjustments without compromising on strength. The spade head design allows operators to apply maximum torque by hand, making it ideal for frequent access panels, electronic enclosures, and machinery guards where speed and convenience are critical. Made from robust steel with a Rockwell B55 hardness, it resists deformation and wear, even in high-cycle applications. The flanged base and fully threaded body ensure a secure, vibration-resistant fit, while the fine thread and Class 2A tolerance provide reliable performance in precision assemblies, reducing the risk of cross-threading and ensuring long-term operational reliability.
