Key Features & Benefits at a Glance
- Effortless hand-tightening with a knurled round head for superior grip in tight spaces, reducing tool dependency and speeding up assembly.
- Exceptional corrosion resistance from 18-8 stainless steel, ensuring long-term reliability in harsh industrial environments.
- High tensile strength of 80,000 psi and Rockwell B83 hardness for secure, heavy-duty fastening that withstands significant loads.
- Precision 10-32 UNF fine threading with Class 2A fit for smooth engagement and reliable performance in applications requiring fine adjustments.
- Low-profile round head design minimizes protrusion, making it ideal for compact assemblies without compromising on usability.
- Partially threaded shank allows for controlled clamping force and easier alignment in varied mounting scenarios.
- Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global standards for industrial components.
Professional Applications & Engineering Value
This 10-32 UNF knurled thumb screw in 18-8 stainless steel addresses common industrial challenges by combining durability with user-friendly design. The knurled round head provides a secure grip for manual tightening in applications where tools are impractical, such as electronic enclosures, machinery panels, and medical devices. Its fine UNF threading and Class 2A fit ensure precise, vibration-resistant connections, reducing the risk of loosening in dynamic environments. With a low-profile head and partial threading, it offers flexibility for adjustable fixtures and space-constrained assemblies, while the corrosion-resistant material extends service life in humid or chemical-exposed settings, making it a reliable choice for OEM and MRO needs.
Specification Summary & Compliance
This thumb screw features a 10-32 UNF thread with Class 2A tolerance for consistent fit and performance. It adheres to industry standards for dimensional accuracy, including a thread diameter of 0.19" and fine thread spacing. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global supply chains.
