Scope and common interpretation errors
For covers, flat gaskets and frame seals. Determine stop dimensions from the complete tolerance stack.
Thread friction affects screw torque, so torque is not a direct measure of gasket compression. A stop that is too high may undercompress; one too low may allow overcompression or support damage.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Separate load paths | Draw the fastener load path and the gasket compression path independently. |
| 2 · Calculate closure limits | Combine stop height, housing flatness and gasket thickness at maximum and minimum conditions. |
| 3 · Validate the complete assembly | Check closed gaps, deformation and leakage. Confirm stop contact is not limited to individual screws. |
A comparison to avoid misinterpretation
At identical torque, assemblies with and without locating stops may show different compression marks. Review closure distribution before changing hardness.
Frequently asked question
Can torque control be omitted once stops are fitted?
No. Fastener integrity and structural loads still need control; stops serve a different purpose.
