Permanent repair of damaged threads. Come see how it’s done!


C-Serts are a permanent thread-repair solution for heavy industrial applications where failure is unacceptable.  C-Serts are backed by a Lifetime Warranty which covers pull-out, back-out, and even thread wear.  Yes, that includes cross-threading and all other forms of operator error.  The "lifetime" in our Lifetime Warranty means for the whole service life of your equipment.  Made from through-hardened tool steel here in the USA, C-Serts won't wear out because they are far hardener than any fastener.  Thanks to our patented design, they won't pull out because they actually cut their way in to form a tight interference fit.  This eliminates the need for a tap and makes for a quick repair.  C-Serts even contain a built-in die to true up damaged or defective fasteners.  C-Serts are particularly useful in mill stands and chocks. The whole idea is to make your repair just once and never make it again.
