  • Can I use the MIII Flooring tools to install 1/2" or greater laminated (engineered) tongue and groove hardwood floors?
    No, Stanley-Bostitch does not recommend this as the fasteners for both the MIIIFS and MIIIFN are too large to be driven into the plywood tongue of laminated flooring. The large size can damage the tongue and may also de-laminate the upper layers of the flooring causing dimpling of the finished product.  However, some laminate flooring manufacturers have tested the MIII tools and have determined that they may be used on their products. Please contact your flooring manufacturer to dertermine the maximum size/gage fastener that they recommend.

  • The MIII Flooring tools now include a large foot assembly designed to protect pre-finished flooring products. Can I purchase this part to upgrade an older model MIII?
    Any MIIIFS or MIIIFN flooring tool, regardless of age, can be upgraded with the pre-finished flooring kit # MIIIFOOT-KIT.
  • How can I convert a MIIIFS floor stapler to MIIIFN floor nailer with the conversion kit?
    The MIIIFN-KIT is used to convert the MIIIFS (floor stapler) to MIIIFN (floor nailer) Attached are the instructions for the conversion kit. 
  • What size pipe threads are on Bosttch tools to accommodate my air fittings?
    Every Bostitch model tool accepts 1/4" pipe thread, with the exception of the models MIIIFS and MIIIFN. These older design flooring tools require a 3/8" pipe thread.
  • Some of the internal components of the MIII tools are difficult to disassemble. Are there any special tools for these models?
    Yes. The MIIIFS and MIIIFN flooring tools have a piston wrench available. This can be ordered as part number BC1009. The MIII812CNCT concrete nailers will use the BC1009 as well, and a wrench, part number BC855 that will aide in removing the poppet screws. These wrenches can be ordered individually and are also included in the MIIISK repair kit.  To order these parts please click on this link to visit our Bostitch ServiceNet website. 
  • Why does my MIIIFN often jam or skip when I get down to the last few nails?
    The MIIIFN has a bypass pusher design which allows the rear load feature. The downside of this design is that the pusher assembly is not able to fully engage the last three cleats to the front nose thus the last three cleats lose the spring tension that keeps them from moving out of position. If the fastener shifts, the driver may miss or jam the fastener. The best way to avoid this is to re-load additional cleats before you are out.
  • How many cleats will I need to purchase for the MIIIFN or MFN-200 Cleat Nailers to install hardwood flooring for an average room?
    Approximately 1,000 cleats are required for every 200 sq. ft. of 2-1/4" width flooring.  Please click here to view and purchase Bostitch flooring cleats online. 
  • I own the MIIIFS flooring stapler, but I want to use flooring cleats.
    Bostitch provides a conversion kit, part # MIIIFN-KIT that provides all of the parts necessary for this conversion. The tool will then drive the Bostitch FLN-150 and FLN-200 flooring cleats.
