The Huck BobTail system includes LockBolts and installation tooling that will deliver you benefits beyond anything that Alcoa Fastening Systems has produced before.

Key Benefits:
Installation speed
Speed of fastener installation has to be seen to be believed with the 1/4 diameter BobTail fastener installing in less than 1 second. The 16mm diameter BobTail fastener installs in 2 seconds, up to twice as fast as any large diameter LockBolt on the market.

No pin-tail or pin-break
Reduced material waste
Low installation noise
Increased corrosion resistance

High Fatigue Strength Thread Form
BobTail thread form is shallower than a common bolt thread, so there is a larger cross-sectional area to spread out the service load, and fatigue strength increases.

The thread form also has a much larger root radius than a common bolt thread, so stress concentration at the thread root is also reduced, which increases fatigue strength even more.

Smooth, shock free installation sequence
Eliminates jolts to the operators arms and hands

Unique helical lock groove (12 – 20mm diameter only)
Holds pin and collar in place prior to installation
