Nylon insert water pump bolts

[jbadams]

Has anyone used these bolts for a water pump? Not sure if I want to use them with the nylon inserts as I am not familiar enough with them. The original bolt heads have worn down to the point that I don’t want to reuse them as I don’t want to strip the heads.

This is on a 65 426 wedge.

Those look like original. They have that same nylon in the threads.

Yup, just like OE

Built in thread sealer. Pump bolts are "wet".

Use standard bolts with Loctite....
The nylon insert was to stop the bolt loosening......but it also weakened the bolt because now it has a hole drilled through it....
