The metal stopper bolt is made of stainless steel (not heat treated).
If heat treatment is required for the bolts, consider the heat treated metal stopper bolt (“-X16,” “-X17,” or “-X18”).
The table mounting block for the metal stopper (and shock absorber) is made of carbon steel (heat treated).
An excerpt from the existing MXQ series catalog regarding special order part number prefixes “-X16,” “-X17,” and “-X18” can be found here.
