| Summary: | Glue-laminated timbers were produced using two species, Kelampayan and
Sesendok. Polyvinyl Acetate (PVAc) were used as binder for glue-laminated
timber manufacturing. The screws with same diameter and length that were
3.5mm and 50mm respectively but have different angle and distance of pitch
were used. The test position was selected at the surface, front and side.
According to test result, it was found that both of pitches of screws are
suitable for Kelampayan species. In side position, Kelampayan species
showed the best screw holding strength and this result is followed by
Sesendok species. In surface position, Pitch 2 has highest withdrawal
strength on the Kelampayan species. In all position, Pitch 1 is suitable for
Sesendok species and Pitch 2 is suitable for Kelampayan species. In both of
pitch, Kelampayan got higher withdrawal strength compared to Sesendok
