Our manufacturing technology radically minimizes variation in all operations. The metal is hardened using a precisely controlled heat treating process. Each DTI is finished using premium cleaning, rust inhibiting, and coating applications. Our quality systems are designed and implemented per the requirements of ISO 9002 using ASQC qualified personnel. This real life data shows, that because of their simplicity DTIs provide correctly tensioned bolts better than any other method.
Tensions are more consistent, with less scatter.
Every lot of DTI's is certified according to ASTM F959 by our lab test reports. These reports show individual test values. Every DTI is stamped with a unique lot mark. All lots are tested and certified at he time of manufacture. Certified mill test reports document the origin and chemistry of the steel used.
