Unique-Bargains 20Pcs Stainless Steel 50x1mm Transmission Round Rod

Stainless Steel Rods for Model Transmission

This pack contains 20 stainless steel round rods intended for mechanical transmission in car model toys and similar maker projects. The silver-tone material resists corrosion and suits hardware or mould applications where small-diameter shafts are required. Each rod measures 50 mm in length and 1 mm in diameter. Builders working on drivetrain components for scale vehicles will find the quantity convenient for spares or multi-axle builds.

Capacity and Limits for Small-Scale Drivetrains

The 1 mm diameter suits lightweight torque transfer in plastic or metal gearboxes typical of hobby-grade RC chassis. Stainless steel provides adequate surface hardness for bushings or simple bearings without rapid wear. The rods are not suited for high-load output shafts or applications requiring larger diameters or keyed profiles. Users needing thicker axles or splined shafts must source different stock.

Ready-to-Use Lengths Reduce Workshop Time

Supplied at a uniform 50 mm length, the rods eliminate the need to cut and deburr raw bar stock for each axle or link. The 20-piece count covers a complete four-wheel drive train with several spares for replacements or design iterations. No additional coatings, lubricants or fasteners are included in the package. Builders must supply their own retaining clips, collars or set screws to secure the rods in place.
