Helicoil Insert, Metal Application, Stainless Steel 18-8, UNC, 5/16"-18 x 1.5D

Internal Thread Size: 5/16"-18

5/16"-18 Stainless steel helical inserts are used to reinforce and repair tapped holes in soft metals.

Feature strong, corrosion resistant internal threads
Engineered to withstand temperatures up to 800 degrees Fahrenheit
The diameter of a helical insert will be larger than the tapped hole (before install)
Once properly installed the insert diameter reduces allowing the helical insert to thread the hole

After installation, E-Z Lok coil inserts will stay firmly in place as the radial pressure of the spring releases.

Stainless Steel Helical Threaded Inserts are ideal for applications requiring additional corrosion resistance, as well as automotive, food, beverage, and other clean-critical applications.

Sizes Listed As:
Internal Thread Size x Insert Length
D = Diameter, (ex #4-40 x 2D is 2 times as long as the Insert's Diameter)
