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 to install Tappers. For optimal fastener performance, the screwgun should be a minimum of 6 amps and have an 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. |
| 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. |
