• 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 >

 

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.
