1/2" white snap lock loop screws offer a very light and inexpensive solution for binding and hanging. Like our standard push-lock posts, they create a very firm and semi-permanent bind that is very difficult to open once closed. They snap together, so no threading or twisting is required. They feature an open loop on the male screw side that lets you add hanging hardware of your choice, such as chains, hooks or string. Bulk plastic hanging screws are also available, please call (866) 537-2244 for pricing.
