ASTM Issues Fastener-Specific Zinc Galvanizing Standard

Jason Sandefur

The ASTM Committee F16 on fasteners adopted a new standard for zinc coating, hot-dip requirements for application to carbon and alloy steel fasteners.
Salim Brahimi of Canada”s Ibeca Technologies Corp. described the new ASTM F2329 standard as “an important milestone in the path embarked upon by Committee F16 to assume and maintain jurisdiction over coating standards that specifically address the concerns of the fastener industry.”
“Historically the subject of coating of fasteners has been relegated to a subset within general coating standards developed and maintained by ASTM committees such as B08 on metallic and inorganic coatings or Committtee A05.
“In many instances important topics such as thread fit, thread tolerances and coating allowance have at best been dealt with in an incomplete manner,” Brahimi told FastenerNews.com.
In the past decade Committee F16 on Fasteners “has endeavored to develop coating standards that apply specifically to fasteners.”
The F16 committee first dealt with organic spin coatings for automotive fastener applications.
Subcommittee F16.03 developed the new standards for the most widely used fastener coatings.
“The adoption of ASTM 2329 was a significant success for ASTM Committee F 16 on Fasteners,” Brahimi declared. With F16 working with A05 potential users including fastener manufacturers, galvanizers, distributors and end users.
Brahimi explained ASTM 2329 was developed to complement ASTM A 153/A 153M specification for hot dip zinc coating on iron and steel hardware. While Specification A 153/A 153M addresses the processing parameters and general requirements of hot-dip galvanizing, ASTM F 2329 addresses concerns and requirements that are specific to the coating of threaded fasteners, Brahimi explained.
