• High tensile strength of 70,000 psi ensures reliable fastening under load, reducing the risk of mechanical failure
• Precise Class 2A thread fit with 10-32 UNF fine threads provides secure engagement and vibration resistance in assemblies
• Full threading along the 1" length offers maximum adjustability and holding power across the entire fastener
• Low-profile round head design minimizes protrusion, making it ideal for applications with limited clearance
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets international supply chain requirements

Professional Applications & Engineering Value

This 10-32 UNF thumb screw is engineered to address common challenges in industrial assembly and maintenance, where tool-free operation and reliable fastening are critical. The Black-Oxide Steel construction provides excellent resistance to rust and wear, making it suitable for environments exposed to moisture, oils, or frequent handling. The fully threaded design and fine thread spacing ensure a tight, secure fit that resists loosening under vibration, which is essential in machinery, electronics enclosures, and automotive components. The knurled head texture offers a non-slip surface for quick adjustments, reducing installation time and improving ergonomics. With a Rockwell B84 hardness and robust 70,000 psi tensile strength, this screw delivers consistent performance in high-stress applications, from securing panels to positioning devices, while its low-profile head fits seamlessly in compact designs.
