Higher Heat Application Shoulder Screw
Higher Heat Application Shoulder Screw
(OP)
Hi All-
I'm using a 304 Stainless Steel shoulder screw that's threaded into a 304 stainless steel plate. The application can reach about 180° Celsius steady state, and will change from there to STP about 6 times a day.
The shoulder screw needs to be removed once a week for cleaning, and the problem is that the shoulder screw is extremely difficult to un-thread after cooling. I am wondering if there is another material I can use for this shoulder screw that may give me better results.
Any input or suggestion is appreciated, and if any more information is necessary, please let me know!
Thanks,

Okay, now I'm thinking of something more sophisticated. A fixed cylindrical sleeve, with an internally engaged plug-in head/flange retained by a mechanism like a ball-lock pin or a Cleco sheet metal tool.

This opens up a new question... If anyone has any ideas of ways to create this joint, other than a thread, please feel free to comment. I will post up a rough picture tomorrow morning.
Thanks again all.

Right now, Item 1 is about .2" thick, and can't get any thicker. There will be 4 Item 3's connected to an actuator that force item 1 upwards. There isn't a lot of force seen on these connections, so a completely rigid setup is not necessary. If anyone has any ideas/thoughts, I certainly welcome them.
Thanks again.
