Expandable Diameter Fasteners

FDI stocks the Shur-LokĀ® brand of Expandable Diameter Fasteners. Unique to your individual application, each fastener is custom-engineered to expand in a hole thus preventing fretting (corrosion or wearing away). These unique bolts, blind bolts, shafts, and cam-actuated shafts can eliminate the need and extra expense of close tolerance machining or press-fit fasteners.
