Snap Hook Fastener

We keep a plastic bag on the back of a cupboard door purely to store plastic bags, crisp packets to recycle, this bag was always falling off so I thought I would remedy this problem by the way of this simple hook fastener.Its about 80mm long and has a countersunk hole for a screw.It does a job so to speak so I thought I would list if for others to use.Prints on its side with no support.Thannks for Looking
