Key Features & Benefits at a Glance
- Effortless hand-tightening with a knurled acetal plastic head for superior grip and comfort in repetitive adjustments.
- Exceptional corrosion resistance provided by 18-8 Stainless Steel construction, ensuring long-term reliability in various environments.
- Precise and secure fastening with a Class 3A UNF fine thread fit, offering high vibration resistance and minimal loosening.
- Space-saving low-profile round head design ideal for applications with limited clearance without compromising on turning leverage.
- Broad thermal compatibility as the acetal plastic head performs reliably in temperatures from 32° to 180° F.
- Maximum thread engagement from the fully threaded shank, distributing load evenly for stronger, more durable connections.
- Global compliance assurance, meeting RoHS 3 and REACH standards for safe use in regulated industries.
Professional Applications & Engineering Value
This 10-32 UNF low-profile thumb screw is engineered to solve common assembly challenges in electronics, machinery, and instrumentation. The combination of a 18-8 stainless steel body and acetal plastic head provides an optimal balance of strength and lightweight, non-magnetic properties. The fine thread and Class 3A fit ensure precise alignment and high resistance to vibrational loosening in dynamic environments. The knurled texture on the head allows for quick, tool-free adjustments, reducing assembly time and improving operator efficiency in maintenance-heavy or frequently accessed panels. Its compliant design makes it a reliable choice for industrial applications requiring repeated manual handling without the risk of corrosion or material degradation.
Specification Summary & Compliance
This thumb screw adheres to UNF thread standards with a 10-32 thread size and Class 3A thread fit for high precision and consistency. The manufacturing ensures a fully threaded 1/2" length with a right-hand thread direction. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material restrictions are met for global industrial use.
