An "L" shaped structure typically used for structural framing and a part used to form the "skeleton" of the robot. Ideal for attaching and supporting towers.

Can be used to support and connect other structural components to stiffen a chassis, can be mounted flush to a piece of aluminum structural metal to reinforce its square holes, can provide a flat surface on a chassis to mount components like the brain, radio, and battery.

A member that has end connectors which provide an additional connection point. They are one of the members included in the chassis kits. A structure system beam used to form the "skeleton" of the robot.

A flexible structure part used to form the "skeleton" of the robot or specialized applications. Similar to the flat plates, but have more flexibility.

A structure member that has excellent strength and bending resistance is great for building robust robots. Another part (system beam) used to form the "skeleton" of the robot. The wider the member, the less likely it is to bend or twist, however will make it heavier.

A piece used to strengthen an angled joint. Pictured are angle, L and plus type.

Framework and working parts of an automobile or robot; framework to which components are attached.

A commonly used type of bearing in the VEX system. This bearing has three holes in a row. An axle is passed through the center hole which allows it to spin freely.

A piece that is used to hold a moving piece (such as an axle to spin freely) in place relative to the rest of the system.

Provides five points of contact for creating a connection between two structural metal components using one screw and nut. Each corner is sized and shaped to securely fit into a square hole pattern of many structural metal components. The center of the retainer is sized and slotted to securely fit a hex nut, allowing a #8-32 screw to be securely tightened without the need of a wrench to hold the nut.

Allows shafts to spin smoothly through the square holes in a structural metal component. When mounted, provides two points of contact within the structural metal. One end contains a post which is sized and shaped to securely fit into the square hole of the structural metal. The center hole is sized and slotted to securely fit a hex nut, allowing a #8-32 screw to be tightened without the need of a wrench to hold the nut. The hole on the end of the retainer provides a smooth round support for a shafts or a shoulder screw to spin in.

Provides two points of contact for connecting one piece of structural metal to another piece using one screw and nut. One end contains a post which is sized and shaped to securely fit into the square hole of a structural metal component. The other end is sized and slotted to securely fit a hex nut, allowing a #8-32 screw to be tightened without the need of a wrench to hold the nut.

Availabe in two thicknesses 4.6 mm and 8 mm. Ideal for application where there does not need to be as much contact surface, such as a shaft between a wheel and a piece of strutural metal. They work well for filling in space on a screw between a piece of structural metal and gear / sprocket when they are being mounted together.

A plate that connects a piece to a shaft so that they rotate together.

Put on drive shafts to stop them or objects on them from slipping.

A thick metal ring that can be locked down on an axle to keep it, or parts on it, from moving side to side.

Are used to separate two parts from one another while creating a rigid connection. A hex shaped bar with #8 - 32 threaded hole cut into each end. They are tightened by using a 1/4" side of the open-ended wrench.

A general term for pieces (such as screws, nuts, bolts, rivets and standoffs) whose primary purpose is to hold two or more components together.

Nonlocking, great for prototyping due to its small size. Fits in the standoff retainer and C- channel easily.

A standard nut that includes a toothed "crown" designed to bite into a mounting surface and prevent the nut from slipping.

A type of hex nut with a plastic ring inserted in one end to grip the shaft of the bolt and prevent the nut from spinning off. This is useful when parts need to be loosely attached to each other without coming apart.

A plastic tie for securing wires or other parts to the robot.

A flat ring of steel that may be split, toothed, or embossed; used in threaded connections to distribute loads, span large openings, relieve friction, or prevent loosening.

Thinnest of the washers/spacers available and have a low coefficient of friction.
