Thread Inserts
Precoil Thread Inserts are made of 18-8 corrosion resistant (AISI 304) stainless steel wire, having an ultimate tensile strength about 200,000 psi, with a hardness of Rc 43-50. The finished surface (8-15 micro-inches) is exceedingly smooth, virtually eliminating friction-induced thread erosion. The stainless steel used resists corrosion under normal environmental conditions. Precoil Thread Inserts can be used with temperatures from -320°F to +800°F.

Precoil thread inserts are used in variety of applications to strengthen the threads. With a easy-to-insert procedure and compatibility range, the Precoil Thread Inserts provide a long lasting solution to the threading with minimum wear and tear.
Precoil thread inserts when installed create a maximum surface contact area with the tapped thread, which ensures the thread anchoring is secure and permanent.
Screw Lock Thread Inserts
Precoil screw-locking insert features a screw-locking feature that retains screws or bolts under the most severe vibration or varying temperature conditions. The insert locking configuration comprises a series of uniquely designed locking chords which, upon the engagement of a screw or bolt, deflect radically to permit the installation of the bolt. Upon bolt entry, these straight segments are flexed outwardly, creating pressure on the bolt. This pressure is applied between the flanks of the bolt thread so that contact area is maximized.
