What is STINGER?

Officially launched by National Nail in 2007 with the introduction of the first non-pneumatic cap hammers and collated caps, STINGER has been “entirely devoted to all things for the building envelope”. Since then, the STINGER family has grown to include pneumatic cap staplers, pneumatic cap nailers, synthetic underlayment, metal roofing accessories, and more.

Why cap fasteners?

Cap fasteners are a recommended best practice installation by top housewrap and roofing underlayment manufacturers such as GAF, DuPont, Tyvek, Grace, and Titanium. Why? Because caps help seal out moisture that can penetrate sidewall and roofing fabrics or material. Caps provide better holding power than just nails or staples alone, which means reduced blow-offs and lateral slippage. It also means that fewer fasteners are needed to get the job done.

  • The STINGER Hammer Tacker makes installing roofing felt, housewrap, and insulation easy and efficient with the use of staples.
  • STINGER Cap Hammers deliver the ease and value of a hammer tacker while getting the job done for a fraction of the cost of a pneumatic cap stapler.
  • The STINGER Cap Stapler sets the pneumatic standard for installing synthetic underlayment, roofing felt, foamboard, and housewrap, and will save you time and labor.
  • The STINGER Cap Nailer is the preferred cap system tool for residential and commercial roofing and sidewall installations where speed is important and a nail is required.

Are DuPont Tyvek WrapCaps compatible with STINGER tools?

Yes, DuPont Tyvek WrapCaps are compatible with specific STINGER tools; however, for best performance and results, it is recommended to use STINGER fasteners with STINGER tools.

How many caps and fasteners do the pneumatic STINGER tools hold?

The pneumatic STINGER tools are designed to hold 200 collated caps and 200 fasteners (staples or nails), which means less time spent reloading.

How many caps and staples do the STINGER cap hammers hold?

The STINGER CH38-2 and CH38A both hold 168 collated caps and 168 staples.

Are the caps for STINGER pneumatic and manual tools interchangeable?

The caps are not interchangeable. If you use the incorrect caps, you will experience feeding issues where caps will skip and only the fastener will be expelled. In addition, there are different quantities of caps per reel. Pneumatic tools have 200 caps per reel and manual tools have 168 caps per reel.

Can STINGER caps/fasteners be purchased separately?

No. STINGER caps and fasteners are always packaged together and cannot be purchased separately.

Can STINGER tools be used without caps?

STINGER tools are not designed for use without the caps and are not designed for use in framing or roofing apart from the caps.

What air pressure (psi) should the pneumatic tools be set at?

The ideal range of air pressure (psi) is between 90-100 psi. If you exceed 100 psi, there is a chance the fastener will be driven through the cap.

Are replacement parts available for repairing STINGER tools?

Yes, replacement parts for all STINGER tools can be purchased from the manufacturer, National Nail.

How often should STINGER pneumatic tools be oiled and what type of oil should be used?

STINGER pneumatic tools should be oiled before each use. Simply putting just four drops in the air fitting is sufficient. If heavy use (more than one StaplePac or NailPac) is planned, then adding another four drops of oil throughout the day is recommended. Each STINGER tool comes with a small bottle of oil. If replacement oil is needed, be sure to only use tool oil from other pneumatic tool manufacturers such as Paslode, Metabo, Bostitch, and Senco. Avoid using other types of oils as many have additives that can destroy seals and o-rings.

Are cap fasteners required for warranties or building codes?

Please consult the manufacturer's installation instructions for required or recommended methods of fastening. In addition, be sure to consult local building codes for any special requirements in your area.
