Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise. Specifications:

Tee nuts are used to put steel threads into wood. Drill a hole sized to fit the barrel, then hammer in the locking prongs until the top of the tee nut is flush with the surface. This creates a strong fastening method between wooden components and other components.
This new custom designed collar clamp has been designed specifically with FIRST Robotics Competition teams in mind. This product is Out of Stock until Mid March
This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load. This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.
The NEW 40:1Tetrix Max; TorqueNADO Motor Gearboxes give more rpm when compared to the 60:1 gearbox included with the TorqueNADO motor. These gearboxes are designed with the same 37 mm diameter as the original 60:1 gearbox, while using the same 6 mm D-shaft and alignment pins, so getting the additional speed you need is a breeze.
The Bumper Wood Corner Bracket is designed to connect two plywood planks together to form a strong 90 degree bumper corner.

Whether you are building an elite custom drivetrain or a championship manipulator, you need your components to stay where they're supposed to. These lightweight spacers come in 3/8", 1/2", and 5 mm hex bores to accommodate the most common shaft types They can also be used on round shafts and bolts (5mm is great for #10 hardware!). If you need to space a lot grab some 1" spacers. If you need ultimate precision pick up some 0.063" spacers. Not sure which spacers you need? Keep a handful of all six sizes in your shop and never go hungry for spacers again!
These spacers are molded in black polycarbonate, a tough, crack resistant material that FIRST teams are familiar with. These spacers should resist stress cracking. If polycarbonate isn't rugged enough for your high load application or you need custom length spacers, check out our Aluminum Hex Spacer Extrusion.
Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?
Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -
General Dimensions:
Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.
The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:
Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM.
