## Summary description

The EFB Elektronik 29311.1 bolt is made of durable metal with a nickel finish, ensuring resistance to corrosion and wear. This high-quality bolt is designed for reliable fastening in various applications, providing strength and stability. Ideal for both professional and DIY projects, it offers easy installation and long-lasting performance.

## Long description

The EFB Elektronik 29311.1 bolt is a UNC 4-40 threaded metal fastener with a nickel finish and an included nut. Designed for general-purpose fastening, this bolt combines a standard imperial thread form with a galvanised treatment to resist corrosion and provide a smooth appearance. Its metal construction delivers mechanical strength suitable for light to medium-duty assemblies in electronics, small machinery, enclosures, and repair projects.
Advantages
The nickel finish and galvanised surface increase corrosion resistance and reduce the risk of surface wear, while the metal body offers reliable tensile strength and dimensional stability. Compatibility with standard UNC 4-40 threaded holes and the supplied nut simplifies installation and replacement. The bolt’s compact size and common thread pitch make it convenient for use in confined spaces and with standard hand or power tools.
Suitable for (tasks / use cases)
Securing electronic components and PCB standoffs where UNC 4-40 threads are specified
Fastening small panels, enclosures, and chassis in light machinery
Repairing or assembling consumer electronics and hobby projects
Applications requiring moderate corrosion resistance in indoor or sheltered outdoor environments
When it may not be suitable
This bolt is intended for light to medium-duty applications; it is not specified for high-strength structural uses or heavy machinery where higher-grade fasteners are required. Despite the galvanised and nickel finish, it may not provide sufficient long-term corrosion protection in highly corrosive marine or chemical environments.
Key specifications
Thread form: UNC 4-40 (imperial coarse thread)
Material: metal (steel-based construction)
Surface finish: nickel plating with galvanised treatment
Pack contents: bolt with matching nut included
Typical applications: electronics, enclosures, light machinery
How to use
Select a mating hole or threaded insert sized for UNC 4-40 threads. Align the bolt through the parts to be joined, hand-start the nut onto the bolt, and tighten with an appropriate screwdriver or wrench for the bolt head and a corresponding tool for the nut. Apply torque appropriate for small metal fasteners to avoid stripping threads; use threadlocker if vibration resistance is required. For repeated disassembly, inspect threads for wear and replace if deformation or corrosion is present.
What to consider before purchase
Confirm that UNC 4-40 thread form and imperial sizing match your application
Verify that the bolt’s material and nickel/galvanised finish meet your corrosion-resistance requirements
Ensure the included nut and bolt length are suitable for the thickness of parts being joined
Usage recommendations
Use standard hand tools sized for UNC 4-40 hardware and avoid over-torquing. For assemblies exposed to vibration, consider a thread-locking compound or a locking washer. Store spare bolts in a dry environment to maintain the nickel finish and galvanised protection.
