Helicoil Free-Running Inserts
Helicoil
Free-Running Insertsis a high-precision
surface of the cold-rolled diamond-shaped stainless steel wire precisely formed
by the spiral coil, for high-precision internal and external thread concentric.
The wire screw is assembled to form a high-precision internal thread that conforms
to the international standard, better than the internal thread formed directly
on the workpiece. Please refer to the following table for specific dimensions.
Color threaded insets
Colored on the surface of stainless steel, mainly for the convenience of the operator can clearly and quickly distinguish between the varieties and specifications of the wire thread. After the color screw sleeve is installed, it is markedly different from the basic color of the die-cast aluminum part (white metal color).This will help to check whether the installation depth of the screw sleeve is suitable and whether it is missing. At the same time, it facilitates the visual management of the warehouse. We have the technology of the domestic patent.

(Bashan), affiliated to China Aviation Industry Corporation, is a specialized manufacturer that produces steel thread inserts for military and civil use more than 50 years. We attained ISO9001 certificate in 1998. Good quality, best price and large capability of production.
Thread insert is a new type of fastener. It is precision formed coils of stainless steel wire having a diamond shaped crossed-section.
There are two forms: free-run type and screw-locking type. Screw-locking type offers a screw-lock effect by polygon elastic safety coils.
Thread insert is used for manufacturing high strength, wear-resistant, high duty and vibration-proof in metallic and non-metallic materials such as Al, Mg alloy, plastic to form M and MJ thread.
Now the insert technology has been widely used in many industries such as aerospace, aviation, electricity, instrument, and chemical fiber and so on.
Having more than 50 years of experiences in this field, and with background of military technology, we can supply both Inch system and Metric system insert to meet customers' need, according to DIN standard. For detailed offer, please give me your specifications and quantity, package requirement, etc.
