From Fasteners Technology International, October 2014
In recent years, there has been a strong resurgence of interest in the wine and spirits industry. One of the advantageous traits of many wines and other spirits is their ability, or in some cases necessity, to age in the bottle or a wooden barrel. This “aging” time transforms the wine or spirit from a drink that may be initially quite nondescript or even “nasty” to one that is of fine quality and enjoyed by the consuming practitioner.
In much the same way, hot rolled rod looks to all but the trained eye like a product ready to go into a cold header and be made into bolts. Like wine though, at this stage looks can be deceiving and a variety of unpleasant surprises may be in store for fastener manufacturers that would consider
using hot rolled rod straight from the mill.
