Thread Inserts in a variety finishes & sizes for increased Fastener holding power
Thread inserts, also called insert nuts, have external knife threads that provide superior holding power in hard and soft woods, particle board and all wood products. They are installed into a material and hold in place. The inside of thread insert nuts have threading made of metal to create a more durible hold. Used wherever field assembly or disassembly could lead to thread erosion or stripping. The long pilot ensures straight driving into a drilled hole. Can be installed with a screwdriver, bolt and nut, tapping head, or EZ LOK driving tool.
Stainless steel threaded inserts are available in coarse and fine threads. Unlike coil inserts, which require a special drill, tap, and installation tool, E-Z LOK threaded inserts for metal are installed using standard tools. Simply drill the appropriately sized hole with a standard drill, tap the hole with a standard tap and then turn in the E-Z LOK like an ordinary fastener with a screwdriver, bolt and jam nut, or an E-Z LOK drive tool.

Brass is an alloy made of copper and zinc. The color of brass can vary from dark to light based on the zinc content; more zinc content produces lighter brass. Brass is prized for its corrosion resistance; however it is quite soft so it is not suitable for all applications. Brass conducts electricity and is also a good conductor of heat. It is often used in pipes, weather stripping, trim, radiators, musical instruments, and firearms.

Stainless Steel Threaded Inserts
Stainless Steel Threaded Inserts by E-Z Lok are machined out of 303 Stainless Steel and feature standard OD threads. This allows for the use of standard taps for installation, no special tools are required.
Stainless Steel Solid wall inserts are commonly used in maintenance departments and in tool cribs, as well as in the molding and metalworking industries. Stainless Steel Threaded Inserts are a quick and simple solution for reinforcing or repairing holes in soft metals.
303 Stainless Steel Inserts are ideal for applications requiring additional corrosion resistance, as well as food, beverage, and other clean-critical applications.
Stainless Steel Helical Threaded Inserts
Helical Inserts are used to reinforce, and repair tapped holes in soft metals. E-Z Lok Helical Inserts feature strong, corrosion resistant internal threads. Helical Inserts are engineered to withstand temperatures up to 800 degrees Fahrenheit.
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. 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, 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.
Stainless Steel Helicoil Inserts are available in 18-8 or 304 Stainless Steel.
EZ Lok drive tools are also available in black alloy stainless steel. The E-Z LOK drive tool is used in your cordless driver.
