BobTail System

“Dots” on the BobTail collar indicates a full swage when at least one is crossed by the swage anvil. Combining an advanced fastener design with the latest in easy-to-use, ergonomic installation tooling, the BobTail system delivers a strong connection and sets a new standard for ease of installation . For Oversized Holes: To optimize clamp, hardened washers such as ASTM F436, DIN 6916 or EN 14399-6 are recommended for use with oversize holes and slots, along with good bolting practice. Unmatched Speed of Installation 1 2 3 4 Insert pin into the prepared hole, spin the collar onto the pin. 1 The installation tool is applied to annular pull grooves. When the tool is activated, a puller in the nose assembly draws the pin into the tool, causing the swaging anvil to press on the collar, drawing up any sheet gap. 2 At a predetermined force, the anvil begins to swage the collar into the pin’s lockgrooves. Continued swaging elongates the collar and pin, developing precise clamp. 3 When swaging of the collar into the pin lockgrooves is complete, the tool ejects the fastener and releases the puller to complete the sequence. 4 Quick, Easy Visual Inspection 1 Pintail-less design means reduced noise, no waste, and improved corrosion resistance. 2 Visual evidence of successful installation provided by installation indicator. 3 Collar material swaged into the lockgrooves forms a permanent, vibration-resistant connection. 4 Low-swage technology allows for faster, lighter, ergonomic tooling with parts that last longer. 3 Howmet Fastening Systems
