BobTail ® The Next ® Generation HuckBolt No Pintail Fast Installation Vibration Resistant 1/2"-1", 12mm-20mm 1 The Huck BobTail System ® Advanced fasteners and tooling delivering ultimate strength, installation speed, and vibration resistance. Representing the most advanced fastening technology to date, the BobTail® System (fasteners and tooling) has been developed to deliver the highest level of performance and reliability. Engineered to meet the unique challenges of a wide range of assembly applications, BobTail offers safe, quiet, swaged-on installation technology in an advanced HuckBolt design. BobTail is designed to deliver superior joining strength in even the most extreme environments. Available in a wide range of sizes and grades, BobTail also offers quick and easy installation, and up to 10 times the fatigue strength of conventional nuts and bolts. Finally, when you factor in the cost of the fasteners with installation and inspection labor, BobTail often provides an overall lower installed cost. BobTail® Benefits 2 ■ No pintail ■ Silent installation ■ Unmatched installation speed ■ No repetitive stress injuries ■ Low overall installed cost ■ Eliminates need for secondary operations ■ Superior strength (fatigue) ■ ■ Vibration resistance ■ Ergonomically designed installation tooling ■ No special training or skills required for installation personnel Quick visual inspection is all that's needed for a quality-assured joint Unmatched Speed of Installation The BobTail® System delivers a lightening-quick installation cycle time for greater productivity – as fast as two seconds*. This quick cycle is due, in part, to the short time required to apply the tool to the pin and initiate the installation cycle. Once the operator engages the trigger, the swage and eject sequence is programmed to complete the cycle without any additional worker input. 1 The pin is inserted into the prepared hole, and the collar is spun onto the pin. 2 3 4 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. 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. When swaging of the collar into the pin lockgrooves is complete, the tool ejects the fastener and releases the puller to complete the sequence. * Based on a typical installation of a 5/8" Grade 8 fastener Secure, Fast Installation 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. Quick Visual Inspection Pintail-less design means reduced noise, no waste, and improved corrosion resistance. ■ Visual evidence of successful installation provided by installation indicator. ■ Collar material swaged into the lockgrooves forms a permanent, vibration-resistant connection. ■ Low-swage technology allows for faster, lighter tooling with parts that last longer. ■ The installation indicator in the collar flange – a proprietary Huck design – indicates the BobTail collar has been fully swaged on. 3 BobTail System ® Not just manufactured. Huck-engineered. Unlike conventional nuts and bolts, which have gaps on the thread flanks even when tightened, the BobTail system is designed for full metalto-metal contact around the bolt thread by the collar. An installed BobTail has no gaps and delivers a more secure connection, providing reliability even in the most sever environments. Installed Gap Comparison HuckBolt In addition, Huck BobTail lockbolts are not subjected to torsion during installation, so they can safely be taken to higher preload values than conventional bolts, resulting in a much tighter joint. COLLAR Standard Bolt NO GAP GAP The swaged collar forms over the lock thread, and eliminates the gap. Transverse Vibration Comparison Regular nuts and bolts have gap, which allows for loosening by vibration. 14mm class 10.9 C L A MP ( l b f ) 25,000 BobTail 20,000 15,000 10,000 5,000 Nut and Bolt 0 0 50 100 150 TIME (sec.) 4 200 250 300 NUT This chart shows nut and bolt clamp scatter is much wider compared to BobTail, and that once vibration begins, clamp load quickly decays with conventional nuts and bolts, while it holds constant with the BobTail.

Lightweight, Technologically Advanced Tooling Newly designed BobTail tooling makes the installation process quicker and easier by reducing the force required to install each fastener. More compact and lighter weight than previous Huck lockbolt production tooling, BobTail installation tools also offer greater operator flexibility as well as extended reach into difficult areas. For tight, space-constrained applications, SWAGEFORWARD® BobTail tools allow the operator to position his or her hand at a safe distance from the working structure during installation. Safe and Silent Performance The BobTail fastener is installed without a pin-break, contributing to the dramatic reduction of noise on the shop floor, and subsequently, improved worker hearing safety. Instances of foreign object damage (FOD) and loose pintail injuries are eliminated. Because BobTail tooling features a smooth, shock-free installation sequence, repetitive stress injuries are eliminated, and overall safety is increased. Model SF20 SWAGEFORWARD® Model SF46 Cost-Efficient Operation Smooth-operating BobTail installation tooling directly contributes to longer tool and component life, while allowing extended tool maintenance cycles. As a result, costs for parts and overall support are reduced, while system uptime is increased. 8 Tooling Selection (Inches) Tooling Selection (Metric) Diameter *Tool Installation Cutter Diameter *Tool Installation Cutter 1/2" SF20 99-7882 99-7882CX 12mm SF20 99-7880 99-7880CX 5/8" SF20 99-7881 99-7881CX 14mm SF20 99-7884 99-7884CX 3/4" SF32 99-7894 99-7894CX 16mm SF20 99-7881 99-7881CX 7/8" SF46 99-7863 99-7863CX 20mm SF32 99-7893 99-7893CX 1" SF46 99-7867 99-7867CX Tooling Weight and Dimensions (Inches) Model Weight Length Height Width SF20 12.7 lbs 5.52 8.48 2.88 SF32 12.5 lbs 5.58 9.03 3.40 SF46 22.3 lbs 7.33 9.455 4.00 Collar Cutter Feature While BobTail fasteners install permanently, BobTail installation tooling features a collar cutter nosepiece that makes fastener removal easier than ever.
