About | The Fastener Distributor Index (FDI) is a measure of current conditions and market sentiment within the private North American industrial fastener distribution industry. Based on a monthly survey and published report, the FDI was developed in 2012 as a service to the fastener industry by the FCH Sourcing Network and analyst Holden Lewis, then with BB&T Capital Markets.

Like the ISM Purchasing Managers Index (PMI), the FDI is a weighted diffusion index, where a reading greater than 50 indicates growth and less than 50 represents contraction. Indeed, the FDI was modeled after the PMI to become a new benchmark for industrial fastener distribution.

Today, with analysis by David Manthey of R.W. Baird, the FDI reflects a robust history of market conditions. David and his team developed a new component for the index called the Forward Looking Indicator (FLI), which attempts to project conditions in the coming 6 months based on respondent input.

The FDI Survey website is a resource than can be accessed by anyone, but it can only be updated by registered users during the monthly open survey period, which occurs during the last week of each month.

Please click-in to Fully Threaded Radio, episode 159, as past NFDA president, Doug Ruggles will join Fastener Technology International Magazine editor Mike McNulty to provide further analysis.
