Basic resistance of nails to withdrawal and lateral loads was studied to determine the strength and failure of gangnails, a modern type of timber connector basically used for wooden trusses. Two types of gangnails manufactured in the Philippines and used in the experiment differed mainly in plate thickness, tooth size and spacing, tooth type, and number of teeth. Test results showed that the strength of gangnails was governed by the tensile strength of the gangnail plate, the shearing strength of the gangnail tooth, and bearing strength of the wood member. Three types of failure patterns were observed, namely, breaking of the plate, shearing of the teeth, and bearing failure in the wood.
