Executions and application
Specify the timber type and density, the panel or component to be fixed, the manufacturer-required pilot hole and edge/end distances. No universal pilot-hole diameter is assigned. Wood drill-point versions do not imply steel drilling capability. Structural applications require the exact execution, the relevant DoP or ETA and connection design verification. Head geometry alone does not certify product performance. Tecfi also documents the TT Woodpecker family: TT02 in yellow zinc plated case-hardened steel and TT50 in passivated, waxed A2 stainless steel. These specific executions are covered by DoP PP 0529/14-630-1-TT, revision 2.01. Tecfi dimensions and performance must be checked against that DoP, not taken from the Ambrovit tables shown here.
