Thank you for viewing. These are Ebi Nuts stored in a factory. They are unused and offered at a bargain price. These are, at most, used but unused items. Please refrain from purchasing if you are looking for something in new condition. No returns accepted. Shipping will be done by removing the nuts from the original box and placing them in a bag. Thank you for your consideration. Lobtex Ebi Nut NSK-6M Lobtex's Ebi Nut NSK-6M is a blind fastener that allows you to easily create female threads from one side on materials where tapping is difficult, such as thin plates, pipes, and plastic plates where welding is not possible. It combines the functions of a rivet and a nut.
