A brad is a small thin nail that is sometimes referred to by carpenters and in construction as a finishing nail. It always has a very thin diameter and a head which is only slightly larger than the nail itself. Brad nail lengths generally range from 3/8ths of an inch to an inch.
Most Common Uses for a Brad Nail
Since brad nails are finishing nails, they are most often used indoors, particularly for nailing moldings or door and window frames. Since you want the head of the brad to disappear into the wood, so it won’t be seen, a nail set is generally used to ‘set’ the brad in, a 1/8th of an inch or so.
A small tack hammer is usually sufficient for hammering in brad nails, though this is up to the individual.
Once the brad nail is set, or counter sunk, into the wood, a small dab of wood filler is put over the hole. Since every one of these holes over each brad needs to be covered and then sanded, it is advisable to use the wood filler sparingly, covering the hole but not making too large a mound.
