New Fasteners For Treated

In recent years, manufacturers of nails and screws have begun to introduce a range of coated fasteners specifically intended for use with treated wood. The new metal fasteners are designed to improve fastener performance in outdoor environments where severe exposure conditions provide a challenge for fasteners in contact with treated wood products.

Wood

coatings that protect the metal portion of the fastener from direct contact with the treated wood and the high moisture conditions that can promote rust and strength reduction in unprotected fasteners.

CSI is currently working with the International Staple, Nail & Tool Association and individual manufacturers of fasteners to evaluate the performance of the new products in comparison to already accepted hot dipped and stainless steel products.

Traditionally, the treated wood industry\\ has recommended hot dipped galvanized or \\ stainless steel fasteners for use with treated \, wood. However, according to CSI, the widespread mis-application of "electroplated" galvanized nails, screws and other fasteners that are only suitable for use in weather-protected applications and untreated wood, has 1ed to poor fastener performance in more severe environments.

Market demand for improved fasteners for treated wood applications is being met with new technology specifically designed to perform in severe exposure conditions. The new fastener systems are based on

According to Dr. Kevin Archer, product development mgr. for CSI, "A number of the new fasteners perform as well as or better than the . acceptable products already in use. Some of the new systems offer an improvement in the long term performance of fasteners in contact with treated wood while offering a price competitive product. The treated wood industry needs to be aware of these new technologies and ensure we are well positioned to adapt our recommendations in line with the new fastener systems being marketed."
