A steady pin, which is renovated from a push pin, contains a threaded stem and an elliptical cylinder head with a vertical concave periphery surface. The threaded stem can provide the steady pin with a better horizontal load holding capability and a better tacking repetability at the same tacked position on a wall or a board when the steady pin is tacked by a user. The elliptical head of the steady pin can generate a proper amount of torque on a steady pin by user\s thumb and index finger such that the rotating motion of the steady pin is easy to be performed. The vertical concave periphery surface on the steady pin head is utilized to generate a vertical force from the user\s fingers to push the steady pin into or pull the steady pin out of a wall, bulletin, or notice board.

A steady push pin comprising a threaded stem with a pointed end and an elliptical cylinder head, which is formed with the cross sections transverse to said threaded stem being larger nearby both ends and smoothly getting smaller from said both ends inwards along the length such that the smallest cross section transverse to said threaded stem is at an optimal location somewhere in between said both ends, whereby said steady push pin can be tacked into a solid media and used as a means to hang or somewhat vertically hold an article on said solid media with both vertical and horizontal load holding capability.
