Stainless Steel Spring Wire 0.8mm x 400mm (40pcs)
The braxan stainless steel spring wire is sized to 0.8mm in diameter and 400mm in length, offering versatile options for DIY and industrial tasks. Constructed from durable 304 stainless steel, this wire resists rust and corrosion while delivering reliable elasticity for long-term use. Its straight, burr-free surface facilitates handling and processing, reducing soft deformation during bending or shaping. The wire’s composition supports a range of applications from crafting to light mechanical assemblies, where consistent tension or return force is needed. The 40-piece pack provides ample quantity for multi-project use or spare components for ongoing projects.
Brass Rod 0.8mm x 400mm (Pack of 10)
These MECCANIXITY brass solid round rods are precision-cut to 400mm and 0.8mm in diameter, suitable for gear shafts, model axles, and small lathe projects. Brass offers favorable machinability and corrosion resistance, making it ideal for prototype parts, bearings, and delicate mechanical assemblies. The high hardness of brass provides structural integrity while remaining workable for milling and turning. A pack of ten provides a cost-effective option for batch manufacturing or replacement parts, whether used in RC models or craft projects requiring a lightweight, durable metal rod.
Fully Threaded Rod M5 x 400mm 0.8mm Thread Pitch (1 Pack)
This MECCANIXITY fully threaded rod is built from 304 stainless steel and measures M5 with a 0.8mm thread pitch over a 400mm length. It’s designed for assembly fastening, screwing into nuts or tapped holes, and adapting to U-bolts or hangers. Common uses include guide rails, machine tools, and other equipment where adjustable fastening is required. The 400mm length and corrosion resistance of 304 stainless steel support reliable performance in varied environments, enabling straightforward installation and durable service life.
Fully Threaded Rod M5 x 400mm 0.8mm Thread Pitch (2 Pack)
A two-pack option of the same M5 stainless steel threaded rods provides flexibility for larger projects or parallel assemblies. Like the single pack, these rods offer strong corrosion resistance and consistent threading, making it easier to assemble and secure components across multiple points. The 400mm length supports longer fixtures and structural elements while the 0.8mm thread pitch ensures precise engagement with compatible nuts and tapped holes. This pair is suitable for bulk projects, educational kits, or workshop inventory.
Copper Flat Bar 0.8mm Thick x 20mm Wide x 400mm Long
The 5PCS C110 copper flat bars are dimensioned near 0.8mm thickness with a 400mm length, ideal for electrical connections, flexible circuit supports, and lightweight structural elements. Copper’s conductivity, hardness, and corrosion resistance support reliable performance in electronics assemblies, prototype wiring, and DIY battery contact projects. The bars come polished and ready for cutting, bending, or machining to fit precise designs, enabling efficient fabrication on a variety of hobby and professional tasks.
Meccanixity Carbon Fiber Strip 400mm x 1mm x 3mm
This carbon fiber strip offers a pultruded profile with a 400mm length, 1mm thickness, and 3mm width. While not 0.8mm, it complements the range by providing a high-strength, lightweight alternative for kites, RC aircraft spars, drone frames, and light structural elements. Pultruded construction aligns fibers in a single direction for improved stiffness and tensile strength. It resists corrosion and high temperatures, making it suitable for demanding environments where weight reduction is important.
Buying Guide: Key Purchase Considerations
- Material properties: Stainless steels (304) resist corrosion and offer good elasticity, ideal for springs and structural links. Brass and copper provide machinability and conductivity, respectively, while carbon fiber offers high strength-to-weight ratios with thermal stability.
- Diameter and length tolerances: Verify that the 0.8mm diameter aligns with your drill bits, holes, or mating parts. Ensure the 400mm length fits your project’s dimensions or can be cut to size without compromising strength.
- Threaded vs. non-threaded: Fully threaded rods enable easy fastening and adjustable assemblies, but require compatible nuts and tapped holes. Consider whether you need smooth shank sections for simple pin connections.
- Corrosion resistance: For outdoor or humid environments, stainless steel and brass offer durability, while copper can oxidize and darken over time. Carbon fiber is highly resistant to corrosion but may require protective coatings in aggressive conditions.
- Machinability and finish: Smooth burr-free surfaces simplify handling and reduce risk of cuts or snags. Brass and copper are easier to machine; stainless steel offers greater rigidity and longevity.
- Package quantity: Packs of 10 or 40 pieces provide bulk options for ongoing projects. Consider your project scale to avoid excess inventory or shortage.
- Compatibility with tools: Check compatibility with looms, lathes, drills, and nuts. Ensure thread pitch and nut sizes match your hardware stock.
- Cost-to-value: While metal rods and wires vary in price by material, the long-term durability and ease of use often justify higher initial investment for critical components.
In selecting components with a 400mm length and 0.8mm diameter, evaluate the intended function—whether structural support, fastening, or conductive use—and balance practicality with material performance to achieve reliable results across your projects.
