In the bail application filed through their lawyer Pankaj Bafna, the arrested officials contended that they need bail as they have small children to look after.
They have also said that contrary to the claim that rod was inserted in Shette's private parts the investigation found nothing of that sort.
Mr Bafna said the complainant and other inmates are continuously changing statement.
Manisha Pokharkar, Wasima Shaikh, Shital Shegokar, Surekha Gulve, Aarti Shingne and Bindu Naikade were arrested last month for assaulting Shette and causing her death.
The court is likely to hear the plea on August 4. Shette (45), serving life sentence, died in hospital on June 23 after she was allegedly beaten up by the jail staff.
