    1/2 in. Hex Collar Clamps, Silver Thin (0.25in) - 1 part

    (124 In stock)

    These custom designed collar clamps have been designed specifically with FIRST Robotics Competition teams in mind. The one-piece collar clamp is a nice fractional 1/2 in. width to make shaft stackups easy. The clamping force is provided by a 10-32 socket head screw, which is bigger than most used in the competition marketplace.  This provides a high-strength clamping solution that shouldn't strip out when you need it most. You can even replace the 10-32 screw if it becomes lost with the screws historically used in the AM14U family of chassis. These thoughtfully designed collar clamps also have small bosses on each side. This allows these collar clamps to be installed directly adjacent to an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation.

    Box Tube Extrusion, 1 X 1 in., .063 Wall Thickness, 6 ft. Length


    These aluminum box extrusions are robust and lightweight solutions for custom robot frames, superstructures and mechanism construction. Made to all of your favorite English sizes, the classic 2x1 thin wall tubing is now joined by its thicker-walled counterpart. We have also introduced two thicknesses of 1x1 sizes that teams know and love to build their medium-sized mechanisms. 

    For smaller mechanisms, we recommend using our 5/8 square box tube that is also compatible with our S3 line of brackets and gussets.

    Available Sizes:

    • 2 x 1 x 1/16 in. (0.063 in.) 6061-T6 alloy
    • 2 x 1 x 1/8 in. (0.125 in.) 6061-T6 alloy
