Snug tight is defined in AS 4100, as the full force of a person with a key Podger standard, or where there is a change in recording speed, or when the key is the impact of solid pneumatic impact. Podger keys are evaluated with respect to the length of the bolt size and strength, and, for example, the order of 450 mm for M20 high strength structural bolts, and 600 mm for the M24 high strength structural bolts.Snug tightening in the following cases:
- The final level of a structural tightening of the bolts in the general run of commercial bolts - category 4.6 / S.
- A final level of tightening bolts high strength structural bolts - category 8.8 / S. The values of the different structures than the procedure should be applied 8.8/TB 8.8/TF and bolts, as described on page 52.
- mid-level gate voltage is applied as a first step in the process of tightening a full - Category 8.8/TF and 8.8/TB.
