Fastener Distributor Index (FDI)

A monthly snapshot of fastener industry operating conditions and sentiment


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.
FDI History

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 monthly FDI report is distributed to participating members, news outlets and organizations and is further analyzed on the popular fastener industry podcast Fully Threaded Radio, with host Mike McNulty of Fastener Technology International Magazine.

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.

A comparison of the FDI and PMI from its inception is available on this historical graph, which represents index data from 2012 to the present, contributed by Bob "GQ" Baer of Abbott Interfast.

Seasonal adjustment was added to the FDI calculation beginning in 2015. The latest FDI and PMI comparison with seasonally adjusted numbers is available on this historical graph.
