Frequently Asked Questions

  • What does the term "Low Fastener Lockout" mean?
    Many of the Bostitch finish tools now feature a Low Fastener Lockout. This is a mechanism that will lock out the trip actuation system so that the tool will not cycle when it is almost out of fasteners. It reminds the operator to load more fasteners so that he/she does not drive blanks and just leave empty holes in the wood.
  • Do you have an MSDS for the Magnalube Teflon grease used in your Nailers?
    This teflon grease is used in many of our nailers. Please check the attached list or your parts breakdown you can search here to assure yours is on it:


  • DA vs FN finish nails & tools

    The main difference between the DA & FN  styles is the nail itself & the angle of the magazine.

    The DA style nails have a "D-shaped" head, that is actually what the D stands for in the model # and the A means angle. This tool (DA1564K) is new as of 2012 and was long awaited, as we have been making the nails to go with it for many years.

    Nails for both the DA1564K or N62FNK-2 (our current FN angled finish nailer) are a 15 gauge, but the magazine is different. Angled at 25 degrees on the N62FN and 34 degrees on the DA1564.


    There is also the FN1664K which is a 16 GA straight finish nailer. These nails are different as well.



  • Can oil be added to the oil free nailers and will this harm the nailer in any way?
    Oil doesn’t harm the nailers. We test for this. When adding oil to the nailer however you end up with oil coming out of the exhaust which is what oil-free tools prevent. 

    Automatic oilers are fine but you need to watch the oiling rate and potential buildup in the tool as it’s at the end of the line. Oil can also rob the system of air volume and flow if it builds up causing reduced power, sluggish cycles, and potential skipping. 

    Just make sure when you finish with the nailer, you unplug the tool daily to expel oil and to monitor the oiling rate of the system. 
  • Will I harm my oil-less tools by putting oil in them?
    Lubricating our oil-less line of tools will not cause harm unless a corrosive/detergent is used. Always refer to your operation and maintenance manual for proper care and safe use of your tool.
  • Can I purchase replacement no-mar tips for my Bostitch model FN1664K finish nailer?
    Yes, the replacement no-mar tips are part # 180213.
  • Can I control how deep my FN1664K finish nailer drives the nail?
    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.
  • Can I purchase a new carry case for my Bostitch model FN1664K finish nailer?
    Yes, the part # for the carry case is 180584.
  • What is the trigger valve kit for the Bostitch model FN1664K finish nailer?
    The trigger valve kit # is TVA15.
  • I just purchased a Bostitch model FN1664K finish nailer. The trigger is stuck and will not move. What is wrong?
    This tool is equipped with a trigger lockout to lock the trigger for safety. To release it, depress the button on the right hand side of the frame just above the trigger. To activate the trigger lock, depress the same button from the left side of the frame.
  • What is the rebuild kit number for the FN1664K?
    The rebuild kit # is FN1664-RK.
  • The Bostitch model FN1664K advertises a Selectable Trigger System. What does this mean?
    The Selectable Trigger System allows the operator to choose between two different modes of actuation with the twist of a selector switch. 1) Sequential Trip Actuation: This mode requires the operator to hold the tool onto the work surface before pulling the trigger. This makes accurate fastener placement easier. It allows exact fastener location without the possibility of driving a second fastener on recoil. 2) Contact Trip Actuation: This mode allows the operator to contact the work surface to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work surface is contacted. This will allow rapid fastener placement. FN1664K owners should carefully read the Tool Operation and Trip Operation Modes section of the Operation and Maintenance Manual before operating this tool.
  • Do I need to oil my Bostitch model FN1664K?
    No, the FN1664K is an oil free design and does not require daily lubrication during operation.
