20 Why Do Your Fasteners Fail at 20 C

If you work in Canada's wood industry, you know that winter changes the rules of the game. But do you know why a nail that performs perfectly in July can become your worst enemy in January?

The science is simple—but brutal: when wood freezes, the moisture in its fibres turns to ice. The result? Frozen wood becomes harder, denser, and loses its natural elasticity.

The Problem: The "Wedge Effect"

A standard nail with a diamond point acts like a wedge. In frozen wood, instead of separating the fibres, it breaks them. This leads to:

  • Immediate wood splitting.
  • Loss of structural integrity.
  • Wasted raw materials and increased production costs.

The Shur-Fast Expert Solution: Precision Engineering

To tame frozen wood, you need to shift from a wedging action to a cutting action.

1. Choose a Chisel Point Nail

Unlike diamond points, a chisel point is designed to cut through wood fibres directionally instead of putting them under tension. This is the critical difference between a strong, reliable structure and a production reject.

2. Specialized Polymer Coatings

In winter, friction heat dissipates instantly. Shur-Fast's proprietary polymer coatings are engineered to remain flexible. They won't become brittle, ensuring maximum adhesion—even during a Canadian flash-freeze.

3. Adjust Your Pneumatic Pressure

Frozen wood offers greater resistance. We recommend increasing your pneumatic tool pressure by approximately 10% to ensure proper, flush driving without damaging the wood surface.
