Shannon Precision Fastener, LLC, was formed in 2004 with the aim of fundamentally reducing variation in the fastener production process. Variation is the enemy of consistent, repeatable quality and cost. Today Shannnon can routinely hold half of traditional tolerances. This is accomplished by leveraging current technological advances. Shannon employs five die progressive cold formers, allowing the individual control of critical characteristics as well as extrusion of both heads and bodies. This control and repeatability from lot to lot allows trouble free automated feeding. Extruded heads with fully filled out corners not only enhance the appearance of our customers' products but also facilitate longer assembly tool life. Extrusion also promotes better material flow during the forming process itself, yielding a stronger, more reliable fastener.
