Stainless Steel Slip Crit Bolt?
Stainless Steel Slip Crit Bolt?
(OP)
Is there such a bolt as a stainless steel (SS) slip critical (SC) bolt?
I have a large piece of equipment going into a pharamceutical facility. The SS equipment is fastened to an SS angle that is bolted to the floor. The angle has slotted holes on the vertical leg for the equipment to bolt to. Therefore, I need a SC connection. I specified galv SC bolts because I didn't think SC SS bolts were even made.
They don't want to use galvanized bolts due to their concern of cleaning solutions interacting with the galvanizing.
Note that the equipment is temporary. It is used for a few weeks several times a year and is stored when not in use. I am not concerned about galvanic action between the carbon steel and the SS because it is temporary and the bolts are replaced with each subsequent use.
Any help here would be appreciated.

Also try google.

I even called a bolt supplier a few weeks ago and they had never heard of SS SC bolts. Maybe the bolt company hadn't heard of them because they deal with the building industry.
In any case, if anyone has information on this I would like to hear about it.

I now have an email into Bufab for further information...

1. simply fill the slot do desired length.
2. weld a plate with standard hole to the angle.
By doing so, you only need a regular SS bolt for bearing type connection.

This equipment wil be installed, used, removed & stored, then installed again several times a year. There are also leveling feet on the unit that could make the hole alignment different with each subsequent installation....
Anyhow, it HAS to be a SC connection.

I think you can torque the stainless bolt to achieve certain level of shear friction, it depends on the friction coefficient of such material, and the force the bolt is to sustain. Add square washer on each face should help.
