HI-LOK™ and HI-LITE™ Nuts and Collars.
Description.
LISI nut and collars products are designed to fit with their related HI-LOK™/HI-TIGUE™ and HI-LITE™ pins. Collars’ wrenching element is designed to break-away at a controlled preload. It has been tested over time and has proven its reliability when installed with non-torque-controlled tools.
Features.
- Controlled preload for collars
- Wide variety of materials and coatings for installation in all structures
- Shear or tension applications, with captive washer, self-aligning or self-sealing option
- Limited access installation, using conventional tooling
- Designed with a counterbore to fit nominal and oversized pins
