The SPC4™ load indicating fasteners allow users to install a bolted assembly with accuracy and confidence. The user can constantly monitor the clamp load on

TC bolts behave differently in a Hydraulic Tension Calibrators (Skidmore) than they do when installed in steelwork. Therefore, TC bolt testing, with hydraulic load cells, will show results 10% higher than what will be realized in the steelwork. Wetting a TC bolt, by rain or otherwise, reduces effective pretension by 10%.

US Bolts - Tensile Strength and Proof Loads ; Proof Load. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. Squirter® DTI (Direct Tension Indicator) Washer ASTM F959M; Load Indicator Washer ASTM F959M : Click here for more on Squirter® DTI Washers.

Load Indicator washers are used to develop the correct tension when installing A325 or A490 structural bolts. load in the bolt. With fasteners displaying typical values of the coefficient of friction (0.08 to 0.18), the tests indicate that the method is a good indicator of the bolt load. At high friction values (>0.25), such as may be displayed by galvanised bolts tightened without a lubricant, the approach has limited potential.

To achieve a minimum pre-load in the fastener of 65% of proof load, the as do load indicator washers - slightly more expensive for slightly more accuracy and

In most cases, load-monitoring cartridges can be retrofitted into customers’ bolts. The Maxbolt™ Knowledge , with its high visibility indicator, capable of being seen at great distances.

"The constant movement of the welding robot was causing the bolts to lose tension. So we decided to retrofit our robots with SmartBolts; now the maintenance technician can look over during welding and visually check that the bolts are secure. This has had a positive impact on improving our overall safety and manufacturing efficiency." Operator

As with all bolts, if you tighten beyond the proof load you may permanently deform the bolt, and therefore the indicator will no longer operate correctly. An easy way to check if a bolt has been significantly yielded is to loosen the bolt and check that the indicator matches the “loose” red color.
