Pneutek Fasteners

pneutek-pins_1

The Pneutek fastener is an alternative to the conventional puddle weld used to attach steel deck to the structure. The forced entry system utilizes compressed air to drive each ballistic point fastener through the deck and into the structural steel supporting the sheet. Pneutek manufactures 4 different pins series, each with a different substrate thickness range – the thickness of steel below the deck sheet determines which pin is to be used.

Pneutek fasteners are manufactured from carbon steel and heat treated to a Rockwell hardness of Rc 53-56 and a minimum tensile strength of 240,000 psi. The pins are mechanical zinc and yellow chromate plated. They are rated for corrosion resistance in accordance with Salt Spray Test Specification ASTM B117. Enhanced corrosion protection available with the optional N2000 coating meets the requirements of the Dade County PA 114 Appendix E, Annex A5 (ASTM G85).

Installation Information

pneutek-install

Fasteners must be driven with the Pneutek Air/Safe fastening system to ensure tight contact between the fastener head and the attached deck as shown in Figure 1. Fasteners shall be located not less than 1 inch from the end of the sheets. Select the appropriate fastener based on the actual substrate thickness. This will determine the allowable diaphragm shears and flexibility factors for PLB-36 roof deck attached to supports with Pneutek fasteners. Note that K64075 and K66075 pins are to be used for attachment of four layers of 20 gage deck or three or four layers of 18 or 16 gage deck.
