    Quick-Release Pins for Blind Holes
    3D CAD models available

    Often used to position and hold parts during assembly and inspection, mate these pins with a receptacle to secure them in blind holes. Install the receptacle (sold separately) in the hole so you can insert the pin to join components. Three retaining balls lock pins in place until released.

    Add-a-Handle Quick-Release Pins
    3D CAD models available

    Customize these pins with a knob or handle (not included) that's the size, shape, texture, and color you want. Pins have a retaining ball that holds them in place until you pull to remove.
    Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.
