21 Gauge Micro Pins

21 gauge micro pins are a good choice for small decorative trim pieces and hardwoods that might split with a larger finish brad or nail, making them a popular choice for cabinet and custom furniture builders. However, they are too small to offer the holding power necessary to keep larger trim pieces, such as baseboards or chair rail, in place, so you'll want to pair your 21 gauge nailer with one that drives larger finish nails, such as a 15 or 16 gauge finish nailer.
