Designed to connect horizontal beams atop a vertical post, the STCBT2Z-KT continues the structural load path into the foundation through the CPT. The cylindrical design allows installations with a common drill bit. The CBT is available in two models designed to connect beams and posts of a variety of sizes. It is part of a concealed connector system that includes the CPT and CJT.

Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the Australian Capacity Factor (φ) or the NZ Strength Reduction Factor (φ), and applicable the k1 modification factors following AS 1720.1 or NZS3603 and (2) the Serviceability Capacity which is the load at 3.2 mm joint slip. Design Capacity is the minimum of test data and structural joint calculation.
For Australia, the Capacity Factor (φ) is 0.85 for nails and screws for structural joints in a Category 1 application. Reduce tabulated values where other Category applications govern.
For NZ, the Strength Reduction Factor (Ø) is 0.7 for ‘other types’ of fasteners for structural joints.
Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor (k1) where applicable. Capacities may not be increased.
Timber species for joint design is seasoned Radiata Pine, which is Australia Joint Group JD4 per AS 1720.1 Table H2.4. Or NZ Joint Group J5 as per NZS3603 Table 4.1.
Lateral loads is in the direction parallel to the beam.
Lag or carriage bolts are not permitted.
Structural composite timber columns have sides that show either the wide faces or the edges of the timber strands/veneers. Values in the table reflect dowel installation into the wide face.
