F959 DTI (Direct Tension Indicators) washers or F959 washers are space washers which come to secure the tension of all 1/2, 1 1/4 and 1 1/2 structural hex bolts. Thanks to their performance and purpose, these washers are the best option to replace tension controlled bolts of these diameters, since the standard does not include these bolt diameters and A325 or A490 hex bolts must be used.
