Assembly of pallet component and fasteners

An assembly of a pallet component comprising fasteners configured for fastening two unit members and an intermediate connector that form the pallet component, with each said fastener comprising:

• an engaging sleeve formed of a tough plastic material, penetrated by a hole, having an end formed as a resilient tenon section having an opening, and having an opposite end formed with a pressing flange;
• and
• a pressing insert formed of a tough plastic material and provided with an upper section having a first outer diameter and a lower section having a second outer diameter, with the first outer diameter being larger than the second outer diameter, with both the first outer diameter and the second outer diameter being larger than a diameter of a hollow column formed by the hole penetrating the engaging sleeve, wherein the lower section of the pressing insert is integrally formed with a projecting ring;
• wherein each said fastener is installed in the pallet component by:
• passing the resilient tenon section at the end of the engaging sleeve through corresponding through-holes of the two unit members or one of said unit members and said intermediate connector with the end and the opposite end of the engaging sleeve pressed respectively against the two unit members or against the one unit member and the intermediate connector;
• and inserting the pressing insert into the hole of the engaging sleeve with the ring projecting from the pressing insert pressed against a wall of the hole of the engaging sleeve, with the fastener being conveniently and rapidly installed between the two unit members or between the one unit member and the intermediate connector to achieve tight and secure fastening.
