S-96115A480 M3.5 Thumb Nuts

Key Features & Benefits at a Glance

• Enhanced manual grip with knurled round head design for secure, tool-free tightening and loosening in confined spaces
• Superior corrosion resistance due to zinc-plated brass construction, ensuring longevity in humid or demanding environments
• Increased load distribution from the integrated flange, reducing surface pressure and preventing damage to assembled materials
• Reliable thread engagement with Class 6H coarse metric threading, providing consistent fit and vibration resistance in dynamic applications
• Quick installation and adjustment enabled by the fully threaded M3.5 x 0.6 mm right-hand design, speeding up assembly processes
• Broad compatibility with standard metric coarse threaded components, facilitating easy integration into existing systems
• Environmental compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices

Professional Applications & Engineering Value

This zinc-plated brass flanged thumb nut addresses common industrial challenges where rapid access, corrosion resistance, and manual operation are critical. The knurled head texture ensures a firm grip even with gloved hands, eliminating the need for tools in maintenance-heavy sectors like electronics enclosures, machinery panels, and automotive assemblies. Its M3.5 coarse thread with Class 6H tolerance offers excellent thread alignment and durability against loosening under vibration, while the flange design distributes clamping force evenly, protecting sensitive surfaces from indentation. Ideal for applications requiring frequent disassembly—such as prototyping, test fixtures, and consumer products—this component reduces downtime and enhances operational efficiency.

Specification Summary & Compliance

This thumb nut features a 9 mm collar diameter, 10 mm head diameter, and 7 mm total height with fully threaded M3.5 x 0.6 mm coarse metric threads conforming to Class 6H internal thread fit standards. Manufactured from zinc-plated brass, it complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and is REACH (EC 1907/2006) compliant as of the latest substance evaluation, ensuring adherence to international environmental and safety regulations.
