M4 Shear Pins


M2 sized nylon screw



Shear pins are a great way to secure your rocket when concerned about drag separation or in a dual deployment configuration. As nylon screws, you simply use a tap to create a hole into your air frame and coupler. Our starter set includes a tap and 10 nylon screws.  The reload pack has 20 screws.  Available in M2 at 3/8″ long M3 at 1/2″ long, and M4 at 1/2″ long sizes.  Please note!  M4 can be destructive to un-reinforced cardboard!  Using CA or Epoxy after tapping is critical to avoid airframe damage!
