Parameters
14mm Dia. Zinc-Plated Steel Metric Huck Bobtail Collar, #MBTC-R20BL is for 14mm metric Bobtail Huck bolts: MBT-DT14-10, MBT-DT14-15, MBT-DT14-20, MBT-DT14-25, MBT-DT14-30, MBT-DT14-35 & MBT-DT14-40.
Our Huck Bobtail collars are designed for full metal-to-metal contact around the bolt thread. When installed, our collars allow Bobtail Huck bolts to have no gaps delivering a more secure connection which provides improved reliability in the most severe environments.
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.
- Pintail-less design means reduced noise, no waste, and improved corrossion-resistance
- Visual evidence of successful installation provided by installation indicator
- Collar material swaged into the lockgrooves forming a permanent, vibration-resistant connection
- Low-swage technology allows for faster, lighter tooling with parts that last longer
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.
Visual Inspection
The installation indicator in the collar flange– a proprietary Huck design – indicates the BobTail collar has been fully swaged on (bottom photo).
