Where it is used
Bolt-down units are used when vibration or lateral force would work a pressed unit loose — typically on moving machinery, tilting tables or anything a forklift reaches into.
- Tilting and lift tables where the unit must not migrate
- Transfer decks on mobile and vibrating equipment
- Heavy pallet and container handling plates
- Structural ball beds built into welded frames
How to specify it
Check the plate thickness and the thread reach before selecting a stud length; a stud that bottoms out will hold the housing off the plate and destroy the load rating.
