Standard DTIs
Here's one way to install a DTI.
This is another way to use a DTI sometimes preferred by steel erectors.
This is OK too, but when both the bolts and DTI's are coated, in
rare situations it MAY be necessary to completely flatten the DTI. See
All the Details (the Fine Print).

You can also use DTI's on the head end of a bolt when the head is turned, and you can use a DTI with a twist-off bolt - call us for special instructions.
