Lock Through Gudgeon

Often used as the top gudgeon when hanging gates for the additional strength provided by the locking shaft which resists any lateral force that may be applied to a gate
Can also be installed upside down to prevent gates being lifted from their hinges
Recommended for most farm gate installations
Long pin prevents gate lifting off.
Thread rolling makes the threads stronger than conventional cut threads and also ensures consistent quality
The shaft is fully threaded for maximum adjustability
Thinner nuts mean more adjustability close to the post
