Abstract
A pen needle having a cylindrical hub including a distal section that is received in a needle holder and a proximal section having threads that mate with a pair of lugs in an adaptor mounted on a medication delivery pen. The distal end of the pen needle includes a plurality of splines that mate with splines in the needle holder to prevent the pen needle from rotating within the needle holder and aid in threading the pen needle onto the adaptor. The pen needle is fully received in the needle holder to shield the proximal point of the pen needle and can only be removed from the needle holder by using the adaptor or a cartridge retainer having the proper pair of lugs thereon.
