SPC4TM Load
Indicating Fastener

in action.
The SPC4TM
load indicating fastener allows users to install a bolted assembly with
confidence. The user can constantly monitor the clamp load of any SPC4TM
bolted joint whether static or dynamic, by attaching a probe to the datum
disc located on the end of the fastener and reading the value on a hand held
battery powered digital monitor. Optional data gathering and storage of the
bolted joint are available.
The
integrity of a bolted joint is jeopardized when fasteners lose their
tension. This loss of clamping force begins during assembly due to elastic
interactions and joint relaxation. Self-loosening continues when the joint
is put in service due to vibrations, temperature changes, shock, etc. The
SPC4TM joint allows the end-user to retighten only the bolts or studs that
have lost their clamp load resulting in a tremendous saving of maintenance
time, money, and replacement parts. For a minimal investment, the SPC4TM
offers maximum joint integrity with optimum performance.

The SPC4TM may be manufactured to many of the ASTM,
ISO, SAE, or any specific customer standards with various types of head
configurations. |
 PC4
load indicating bolts verifies the actual clampload. Torque Wrenches are no
longer needed. Superbolt and rotabolt are good products. However, superbolt
and rotabolt can only verify one set value. DTI washers only verify one set
load. Maxbolt load indicating fasteners continuously verify the actual tension
load or clampload. These are the new generation of load indicating bolts. More
robust than your load cells. Can stand up to the elements more than load
cells. Load cells are for laboratories, load indicating bolts are for industry use. Why SPC4 are better?
