23 gauge brads are a new addition to the finer, finished market and fill the gap between the finer 23 gauge wire pins and an 18 gauge brad. They offer significantly more power holding than the straight pin, but the head is still a fraction of the size of an 18 gauge brad. This is ideal in situations where more holding power is needed than is provided by the straight pin, but the minimum of marking where the wood is fastened is required. Please note: 23 Gauge brads will only work on tools specifically designed to accept them, including the nikle 1 - 3/16" and 1 - 9/16" 23 Gauge pinners, and the cadex 1 - 3/16" and 2" 23 caliber pinners.
