A thin wire nail with a tiny head or a slight side projection instead of a head.
A thin, small nail, with hook projection at the top on one side rather than a head, or periodically with a tiny domed mind, similar to that of an escutcheon pin.
A paper fastener, a fastening product formed of thin, soft steel, including shim brass, with a round mind and a-flat, split shank, which can be spread after insertion in a hole in a stack of pages, in much the same means as a cotter pin or a split rivet.
A thin nail, usually small, with a slight projection towards the top on one side instead of a head; also, a small line nail, with an appartment circular head; sometimes, a small, tapering, square-bodied finishing nail, with a countersunk head.
A slender level nail having, as opposed to a head, a small projection using one part. It is used if it is desirable that mind shouldn't project, as with joinery, cabinet-work, and pattern-makers' work.
