    1/4-20 x 7/16 Tee Nut

    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.

    Bearing, 1/2 inch Hex Bore, Flanged, (FR8ZZ-HexHD)

    (187 In stock)

    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.


    • Inside diameter: 0.500-0.502 inch hex bore
    • Outside diameter: 1.125 inch
    • Flange thickness: 0.062 inch
    • Overall thickness: 0.312 inch

    Hex Molded Spacers, 1/2 Hex, 0.5 inch length


    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.
