TEKS®
Exterior Rigid Insulation Fasteners
The original self-drilling fasteners designed specifically for rigid insulation.
Applications
 | Roof and wall panel over rigid insulation to steel framing. |
| Roof panel over spacer block and insulation to eave purlin. |
Product Features
| Unique rider section stops panel jacking, point burnout and breakage. |
| High thread under the head prevents panel stripout. |
| Improved in place aesthetics. |
| Available in Scots® and Maxiseal® headstyles. |
| Maximum pullover performance. |
| Excellent driving stability. |
| Seals when driven at an angle. |
| Fastens the broadest range of insulation thickness. |
| Point has precise cutting edges to improve drill performance with less effort. |
| Non-walking point provides fast material engagement. |
| Point to thread design maximizes pullout performance and minimizes backout. |
| Climaseal® finish provides excellent corrosion resistance and lower tapping torque. |

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.
Installation Guidelines
| 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. |
| New magnetic sockets must be correctly set before use. Remove chip build-up as needed. |
| 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. |
