Specification Brand : RAW PRODUCTS CORP BulletPoint1 : Helical Inserts are used to reinforce, and repair tapped holes in soft metals. They feature strong, corrosion resistant internal threads. BulletPoint2 : Helical Inserts are engineered to withstand temperatures up to 800 degrees Fahrenheit. BulletPoint3 : Helical Inserts are made of 18-8 Stainless Steel wire which is formed into a diamond pattern for strength and then wound or coiled into a spring shape. BulletPoint4 : Before installation, the diameter of a helical insert will be larger than the tapped hole, but once properly installed the insert diameter reduces allowing the helical insert to thread the hole. After installation, inserts will stay firmly in place as the radial pressure of the spring releases. BulletPoint5 : Stainless Steel Helical Threaded Inserts are ideal for applications requiring additional corrosion resistance, as well as automotive, food, beverage, and other clean-critical applications.
