BoltSafe load washers are specifically designed to measure and monitor bolt load in bolted constructions. This can be done as well during assembly as over time. Measurements are very accurate, which enhances safety. Knowing the exact bolt load makes the bolted joints more dependable and gives better control over the construction. Place a BoltSafe load washer on the non-driven side of a bolted connection, preferably under a nut. The forces that are applied to the washer while tightening the bolt will result in minor deformations of the stainless steel washer. This causes changes in the electrical resistance, which can then be measured. We use this data to determine the bolt load very accurately at any given moment.
BoltSafe load washers are used for many applications and in many industries. For example, for Structural Health Monitoring and in temporary constructions, where they make sure that the constructions don’t collapse. We offer our washers in two versions: a regular version and a stronger version that can withstand 15% more load while keeping the same dimensions.
