Titanium Helicoil

Titanium Helicoil

(OP)
Hi All,

I'm looking for titanium helicoil in the 3/8-24 size.  It's equivalent in SS would be MS21209F6-10.  I'm looking for a vendor who currently makes this part.

Thanks all!
Angela

RE: Titanium Helicoil

Helicoil is a registered trademark of Emhart Fastening Teknologies, therefore they are the only vendor who could supply this part.  You should visit their Internet site:

Thanks for the response Cory.  I've already talked to an Emhart representative about the titanium helicoil, but she told me they had no plan on manufacturing any in the near future.  So I'm looking for a threaded insert that is made from titanium.

RE: Titanium Helicoil

Why do you need this type of
material specifically?  It is
an odd request.  What kind
of tensile values are you using
to tighten the bolts?

RE: Titanium Helicoil

Consider A286 material it is more common in the aircraft industry.

RE: Titanium Helicoil

I need this material for chemical compatability with saturated brine solution and chlorine gas used for water treatment.  I can either use titanium or hastalloy.

RE: Titanium Helicoil

Why do you need a thread insert?  Rarely are they "mandatory" items.  You should be able to design a threaded joint that doesn't use one - it may require extra axial thread engagement, a thread adhesive, or many other changes, but it is possible.

Cory

RE: Titanium Helicoil

Can you use a keensert
instead of a helicoil?
It may be another option.

RE: Titanium Helicoil

Can you use a tapered plug of sufficient size to be drilled and tapped to the proper size from the opposite side of your part?

I have used this approach on several Titanium and alloy components where I could get to the backside.
