Fastener Pull-Through Testing
The Fastener Pull-Through Testing measures the force required to pull the head of a pallet fastener through a deck board. It determines the force required for a pallet connection to fail due to force parallel to the axis of the fastener.
Fasteners are measured by length and width of the shank, angle and type of the thread, shape and size of the head. And, fasteners are tested for how much force it takes to bend them, and how much force it takes to pull them out after they’ve been driven into any particular substance (wood, metal, plaster, etc…). The more force that it takes to bend or pull the fastener, the stronger that fastener is, which in turn leads to a stronger finished product.
