High Fatigue Strength Thread Form
The document describes a fastener with a shallow thread and large root radius designed to increase fatigue strength. It is maintenance-free, mechanically locked, and requires no torque or re-torque.

Installation Features
An installation indicator on the collar allows for visual inspection, applicable for diameters of 12mm and upwards. The swage indicators indent upon completion of installation.

Key Benefits
The fastener offers easy, shock-free installation, eliminating jolts to the operator's arms and hands. It produces no pin-tail or pin-break, resulting in no material waste, low installation noise, and increased corrosion resistance. A unique helical lock groove holds the pin and collar in place before installation.

Performance and Speed
The fastener provides consistent clamping and does not loosen under extreme vibration, unlike conventional nuts and bolts. It installs in only 2 seconds, making it up to twice as fast as other large diameter LockBolts.

Technical Specifications
The document includes tables detailing minimum installed strength values, installed dimensions, head dimensions, collar dimensions, and grip range and length. It specifies the tooling required for different diameters and provides information on coatings for corrosion resistance.

Tooling and Maintenance
The tooling system offers lower maintenance costs, increased jaw and anvil life, and increased piston and seal life due to lower hydraulic operating pressure.

Coatings
Various coatings are available to meet market demands, ensuring installation requirements, mechanical performance, and corrosion resistance. All finishes are free from hexavalent chrome and comply with European directive EU 2000/53 Annex 2.
