High Strength Shafts & Hardware
High Strength Shaft Hardware is a stronger version of the standard VEX shaft system, designed for robots that require more torque and durability. These 1/4" shafts resist twisting and bending, making them ideal for drivetrains, gearboxes, and other high-load mechanisms.
Use High Strength Bearings to support rotating shafts and Spacer Kits to properly position components while reducing friction.
VEX V5 2", 3", and 4" High Strength Shafts are slightly shorter than their corresponding #8-32 standoffs, allowing them to sit on bearings between structural pieces without requiring cutting.
NOTE: 1/4" High Strength Shafts can only be used with 1/4" accessories, including:
- The High Strength Gear Kit (276-2250)
- The 84T High Strength Gear (276-3438)
- 3.25" Wheels that include a removable wheel insert
1/4" High Strength Shafts are tougher, stronger, and ready for even the most stressful robotic applications. These thicker shafts are more resistant to both twisting and bending fatigue, meaning that you should have no fear of designing high-torque gearboxes or high-impact drivetrains.
- Size - 0.25" (6.35mm) Square Bar
- Works with all VEX V5 High Strength Gears
- Works with the 3.25" Omni Wheel and 3.25" Traction Wheel
- Four lengths: 2", 3", 4", 24"
- Use the 24" to make your own custom length shafts


Removable High Strength Shaft Inserts for High Strength Gears and some wheels that allow for versatility in user application. Switch from a driven gear (square hole) to a free spinning one (round hole) in seconds.
- Increased versatility during design and construction
- Free spinning plastic and high strength metal inserts available
- Fits VEX V5 drive shafts (0.125" square bars)


The High Strength Shaft Bearing is a larger version of the Bearing Flat that is designed for the 0.25" High Strength Shafts.
VEX V5 2", 3", and 4" High Strength Shafts are actually designed about 1mm shorter than their respective 2", 3", and 4" #8-32 Standoffs.
This means that if you use standoffs to hold together two pieces of metal, the High Strength Shaft can rest on High Strength Shaft Bearings attached to those two pieces without any cutting required.
- Mounts directly onto VEX V5 structure
- Low friction allows shafts to turn smoothly
- Mount with Screws & Nuts or Attachment Rivets




High Strength Shaft Adapters adapt the high strength shaft bores in gears, sprockets and wheels to 1⁄8” square shafts.




High Strength Spacers are designed for use on VEX V5 High Strength Shafts. Spacers are often used to properly position objects on a shaft or to reduce friction between rotating objects.
- Four sizes available
- Eliminate slop on shafts
- Add space between metal parts
- Diameter - 0.39" (10mm)
- Hole - .25" square
- Height - .0625", 0.125", 0.25", 0.5"
