Tuthill P212-3-S Stainless Steel Stud for Pump Service
The Tuthill P212-3-S is a genuine stud, made in stainless steel, for Tuthill pump gland and cover stud positions. It is easy to treat a pump fastener as a commodity, but the load path through a cover or a gland joint depends on it being the specified part. Buying the listed part is the cheapest way to take that risk off the table.
Studs rather than bolts are used where a joint is opened repeatedly, because the thread stays in the casting and only the nut is worked. The matching stainless nut is P203-4-S. Replace a stud whenever the exposed thread has been damaged, since a partly stripped stud will not carry an even gland load. Replace anything that shows thread damage or a rounded head. The cost of the fastener never comes close to the cost of extracting a broken one from a pump housing.

Frequently Asked Questions
Q: Can I reuse the originals?
If the threads are clean and the head is undamaged, usually yes. Anything stretched, corroded or rounded should be replaced.
Q: Can I substitute a hardware store fastener?
It is not worth the risk. Grade, thread form and length are all specified, and a fastener that fails in a pump cover takes the pump with it.
Q: Why is the stainless version listed separately?
So the fastener matches the casing. A stainless pump built with plain steel fasteners gives corrosion a starting point at every joint.
Q: How tight should it go?
Even and gradual, working in an alternating pattern across the joint. Check your service instructions for a torque figure before guessing.
