The "Christmas tree gecko" is a real fastener, also known as a "Christmas tree anchor bolt" or "Christmas tree expansion bolt"; it has an expansion sleeve section with a dense ring of teeth that looks like a Christmas tree on the side, hence the name. When installing, tap the whole into the pre-drilled hole. When inserted, the insection will produce huge friction, and when the force is reversed, the insection will open and "bite" the hole wall, forming a fixed. The Christmas Tree Gecko is designed to provide a quick, secure hold on hollow, porous or softer substrates.

Gypsum board gecko is a special anchor bolt specially designed for hollow and low-strength boards such as gypsum board. It mainly solves the problems that the self-tapping screw is not firmly fixed and the common expansion screw can not be used. It is directly screwed into the prefabricated hole of gypsum board like a screw, and is fixed by the huge friction and mechanical bite force between the thread and the gypsum board material. When installed, the inside forms an anchoring claw. It is designed to safely hang objects from gypsum board partitions or suspended ceilings.

The hollow gecko is a metal expansion anchor bolt (for all-metal) in the national specification, or more specifically, an internal thread type/internal force type expansion anchor bolt; the hollow gecko is a cylindrical (sleeve type) metal expansion part, which is usually composed of a conical screw rod with an internal thread at the tail and an expansion sleeve (metal sleeve) sleeved outside; During installation, the whole body is inserted into a pre-drilled hole, and when the nut or bolt is tightened, the internal conical screw is pulled to force the external metal sleeve to expand and open, so that a huge friction force and a mechanical bite force are formed inside a wall body or a base material to achieve a fastening effect. Its core use is to solve the problem of "hanging heavy objects safely and firmly on hollow and loose walls".
