Shaft Round Rod Axles 2mm x 70mm (100 PCS) - Hobby DIY Pack

In this review the reviewer looks at a simple but useful pack of model hardware: 100 round shaft axles sized 2mm by 70mm for STEM and hobby projects. The bottom line is that this pack is for makers who need a large quantity of uniform metal shafts for cutting, drilling and fitting into small RC toy vehicles and other models; its biggest selling point is the volume and consistent size, which makes stocking and repeated builds far easier. The review focuses on fit, versatility and value for small-scale DIY work.

Key Features

• 100 pieces per pack: A large quantity means you can use multiple shafts across projects or keep spares for repairs without hunting for replacements.
• Standard diameter: The 2mm diameter fits many small model hubs and couplings used in RC toy cars and helicopters, reducing custom machining for simple installs.
• Cut-to-length convenience: Each 70mm shaft can be trimmed to the exact length you need, offering flexibility for axles, drives or linkages.
• Multi-use for STEM projects: These shafts serve well in classroom builds and hobby prototypes where repeatable, low-cost parts are required.
• Compatible with small driveline systems: The uniform shaft dimensions make it easier to create consistent assemblies for power transfer in mini drivetrains.

Who It's For

This pack is aimed at hobbyists, educators running STEM workshops and model builders who frequently work on small RC cars, toy helicopters and similar vehicles and need consistent, replaceable axles. Anyone making multiple builds or teaching hands-on mechanical concepts will find the quantity and simple dimensions especially useful.

It is not intended for heavy-duty or high-torque full-size applications, and builders who require hardened, precision-ground shafts with certified tolerances should look at specialty suppliers. For light model work and classroom use, however, this pack is a practical, low-cost option.

Pros & Cons

Pros

• High count provides good value and ready spares for repairs and iterative builds.
• Uniform 2mm diameter simplifies part selection and compatibility with small hubs and fittings.
• 70mm length gives room to cut custom sizes for many model applications.

Cons

• Not specified as hardened or precision-ground, so may be unsuitable where exact tolerances or heavy loads are required.

Specifications

Our Verdict

For educators and hobbyists who need a bulk supply of simple, cut-to-length axles for light RC and model work, this 100-piece pack is practical and economical. It delivers consistent size and flexibility for many DIY builds, though those needing precision or hardened shafts should consider a more specialized option.
