Review on Senco Fastening Systems DA21EPBN 4000CT: Exceptional Performance and Reliability by Terry Wright

Made in the USA, these Senco fasteners are my go-to for all my air nailers, finishing nails, and pin nailers. The metal is of high quality (they are not plugged in, they are not pretzels), the sorting is excellent and the galvanizing (possibly these are bare nails and not galvanised) is good. Working with cheaper imported nails (with the possible exception of Hitachi which for some reason are made in the UAE) can be annoying because. the full range of problems they cause. I've run countless of these Senco finishing nails through my Bosch Airhammer nail guns without a single jam, misfeed, etc. and they automatically pretzel when driven. Senco had many excuses when contacted, but the most telling thing is that I haven't seen them anywhere in several years - maybe Senco decided their reputation was worth a few extra pennies in manufacturing costs? Rating applies to US made nails only. We recommend!
