Fastener and a part having the same

A fastener for securing a part to a panel, the fastener comprising:

• a head configured to be anchored to the part, and
• a locking member extending from the head to a distal end;
• a cage removably engaged with the locking member and configured to partially surround the locking member;
• the locking member comprising:
• at least one protrusion spaced from the head, and
• a tool engaging head at the distal end,
• wherein, when the cage is engaged with the locking member, the tool engaging head at the distal end of the locking member is exposed for tool access through an opening in a distal end of the cage;
• wherein, in use, the locking member extends through an opening of the panel such that the head is retained on a first side of the panel, the distal end of the locking member is disposed on a second side of the panel, and the at least one protrusion abuts the second side of the panel to secure the panel to the fastener;
• wherein the fastener comprises a resiliently deformable portion arranged such that rotation of the tool engaging head deforms the resiliently deformable portion and moves the at least one protrusion out of abutment with the second side of the panel to release the panel from the fastener;
• and
• wherein the resiliently deformable portion comprises a deformable head part that is directly connected to the head and located such that, in use, the deformable head part is located on the first side of the panel with the head and at least partly overlies regions of the panel such that at least a deforming portion of the deformable head part overlies the regions of the panel.
