Critical joints require controlled bolting throughout their service life to maintain performance, enhance safety, save time, and improve uptime. However, the term is more often applied to installation than to the service life of the bolted joint. Valley Forge & Bolt’s (Phoenix, AZ) family of load-indicating fasteners makes it possible to monitor bolted joints after installation and to always know fastener tension regardless of the service interval.
While there are no bolts that tighten themselves yet, the tension-based monitoring system of Valley Forge load-indicating fasteners is a reality, offering far greater accuracy than torque-based methods. Valley Forge & Bolt offers controlled bolting with technology that makes it possible to measure the tension directly from the bolt, not relying on inaccurate torque-based measurements. Accurate to within a +/-5% of minimum yield of the fastener, and ASTM F2482 compliant, now bolted joints can tell you their exact percentage of load at any time.
