Load
Sensing Bolts & Studs from Strainsert, with built-in
strain gauges, permit:
• Measurement of loads induced in fasteners
• Accurate tightening of fasteners within 1% of induced
load
• Uniform tightening of fasteners in a bolt pattern
• Overload detection in bolted machinery
• Use of fasteners as load-link transducers
• Quarter-, and full-bridge configurations
How Load Sensing Bolts & Studs from Strainsert
Can Be Applied:
• Fasteners can be accurately tightened and the preload
measured to a tolerance of better than 1% of the maximum
load. In the past, the only possible method of measuring
load was with a torque wrench. The accuracy of a torque
wrench in the hands of an experienced operator is, at
best, 20%.
• Bolted equipment can be inspected after assembly. There
is no practical method except with internally gauged bolts
to measure preload on a tightened bolt.
• Internally gauged fasteners strategically placed in
equipment can act as built-in sensors for overload detection.
• Assemblies can be monitored and inspected under simulated
or actual service conditions to see if any external forces
exceed the preload. Overloads due to vibration, shock,
etc. can be easily measured at any time during the life
of the assembly.
• Very accurate analysis of bolt loading can be made over
a continuous time period. In applications of this type,
internally gauged bolts become a new basic research tool.
• Gauged bolts and studs can be used as inexpensive load
cells.
