Field Support for Structural Bolting
Below you'll find information commonly needed in the field.
1. Installation and Inspection Instructions
Installation is as easy as the following 3 steps:1. Calibrate in a skidmore
2. Snug the array of bolts
3. Drive it 'Till It Squirts

2. Bolt Torque Requirements
How much torque does it take to tension a bolt? Because torque at specific bolt tension varies by as much as +/-30%, even within a specific set set or lot of bolts, Torque tables are not allowed for structural bolts. If a torque value is to be established for a particular bolt grade and diameter, the Research Council rules are as follows:Read More
3. Bolt Tension Requirements
From the Research Council on Structural Connections, the minimum bolt tension is as follows:Read More
4. Flat Washer Chart
For all squirter® DTI's over larger holes, in order to make the squirt feature function correctly, it is necessary the correct ID and OD flat washers both under and over the squirter® DTI. For a table of the dimensions on these "special" flat washers.View Chart

Lubriacants knock down the torque resistance by about one third every time. Available in fluid or stick wax.View available lubricants.
7. Wrenches
Now there is an alternative to impacting, and Applied Bolting sells it. It's our Maeda-built reaction-arm non-impacting 900 ft-lb electric wrench. We sell them to erectors who don't want to use air tools, at least not for all their bolts. These erectors put the DTI on the nut end, and don't bother to hold the roll.View the details

9. What is meant by "Snug Tight"?
The RCSC defines this as the point where the connection plies are in firm contact, and can be obtained by the full effort of a man on a spud wrench. With DTI's, life is much simpler...Read More
