Can I control how deep my FN1664K finish nailer drives the nail? Support October 03, 2020 18:17 Yes, the tool has a Dial-A-Depth fastener control feature. The fastener control adjustment allows from flush to work surface to shallow or deep countersink. Related articles Does the GBT1850K offer an adjustable depth control? Do we have a manual for the Bostitch® N55C or N55CD? BTE550 instructions My pneumatic nailer / stapler will no longer drive the fastener completely; it seems to be losing power. Can this be repaired? I just purchased a Bostitch model BT1855K brad nailer. The trigger is stuck and will not move. What is wrong? Comments 0 comments Please sign in to leave a comment.
