All our shackles are made in China, and are supplied highly polished.
Material is carbon steel. G80 material is alloy steel .
The shake proof shackle has both heads threaded. The pin will not fall out, but may still be unscrewed from the partially threaded second head.
The shake proof shackle pin incorporates an innovative polyurathane ring which enhances the fit of the shackle pin. Once in position the shackle pin will not vibrate loose.
The shake proof shackle incorporates the Smart-Lock pin. This pin benefits from a unique locking mechanism. When the ring is threaded into the shackle body the ring acts like a viscous liquid and binds itself to the internal threads in the shackle head.
Shackles are the one of the most used rigging fittings. Because the pins are removable, they are used to make connections to slings, rope, cable, etc. In the category of steel fittings, we have three basic types of shackles - screw pin anchor, bolt type safety anchor and screw pin chain.
Most all load rated shackles are forged. Forging is the process of heating a piece of steel and hammering it into shape. This process creates the desired steel grain structure and makes the fitting stronger. The other key process to making shackles is heat treatment. The process of quench and tempering makes the shackle body and pin stronger, yet ductile. Basically, this process allows the fitting to bend before breaking.
There are two basic shapes for shackles and they are either anchor pattern or chain pattern. The anchor pattern shackles are more popular and widely used because of increased area on the inside of the shackle body. This allows for more articulation with the item it is connected to.
The shackles offered by us are made to meet the performance requirements of U.S. Federal Specification .
As a protective coating, shackles are hot dipped galvanized or galvinized and painted.
