Wood-to-Metal Fasteners
No pre-drilling, fast, efficient attachment of wood to steel.
Applications
 | Plywood roof and floor sheet to steel frames. |
| 2 x 4 headers to steel frames. |
| Plywood fascia to steel frames. |
Product Benefits
| Point has precise cutting edges to improve drill performance with less effort. |
| Special winged fasteners ream a hole in wood preventing thread engagement during drilling. |
| Wafer head design has a large bearing surface ideal for plywood. |
| Flat head design countersinks and seats flush in wood. |
| Gray Spex™ finish provides excellent corrosion resistance and lower tapping torque. |
| Compatible with ACQ treated wood. |

The values listed are ultimate averages achieved under laboratory conditions and apply to Buildex manufactured fasteners only. Appropriate safety factors should be applied to these values for design purposes.
| A standard screwgun with a depth sensitive nosepiece should be used in install Teks. For optimal fastener performance, the screwgun should be a minimum of 6 amps and have a RPM range of 0-2500. |
| Adjust the screwgun nosepiece to properly seat the fastener. |
| Worn or damaged bit tip should be replaced. |
| The fastener is fully seated when the head is flush with the work surface. |
| Overdriving may result in torsional failure of the fastener or stripout of the substrate. |
| The fastener must penetrate beyond the metal structure a minimum of 3 pitches of thread. |
| All #10 diameter "Winged" parts must be driven into a minimum of 16 GA steel thickness. |
| All 1/4 and #12 diameter "Winged" parts must be driven into a minimum of 1/8" steel in order to break the wings consistently. |
