Why Choose E-Z Coil Kits?
E-Z Coil kits are useful when a tapped hole has damaged, stripped, or worn threads and the part still needs to accept a threaded fastener. A thread repair kit can help restore the internal thread so the original fastener size can be used again in compatible applications.
This category includes E-Z Coil economy thread repair kits and metric E-Z Coil economy thread repair kits. These kits are commonly selected for maintenance work, equipment repair, shop use, machinery service, and threaded hole repairs where a stainless steel insert system is needed.
Common Uses for E-Z Coil Kits
E-Z Coil kits are commonly used for repairing damaged threads in machinery, equipment, engine components, brackets, housings, fixtures, maintenance parts, shop tools, aluminum parts, and other compatible threaded assemblies.
They are especially helpful when replacing the entire part would be expensive, time-consuming, or unnecessary. Match the kit to the original thread size, thread standard, thread pitch, base material, and repair requirements before installation.
How E-Z Coil Thread Repair Kits Work
E-Z Coil thread repair kits use a threaded insert that is installed into a prepared hole to create a new internal thread. The repair process typically involves drilling, tapping with the correct insert tap, installing the insert, and preparing the repaired hole for the matching fastener.
Proper installation matters. The drill size, tap size, insert length, installation tool, thread direction, and thread pitch must match the repair kit. Always follow the kit instructions for drilling, tapping, insert installation, and tang removal when applicable.
Inch and Metric E-Z Coil Kits
E-Z Coil kits may be available for inch thread sizes and metric thread sizes. The thread system matters because inch and metric threads are not interchangeable.
Choose inch E-Z Coil kits for UNC or UNF threaded repairs. Choose metric E-Z Coil kits for metric-threaded parts, imported equipment, automotive applications, and machinery that uses metric hardware.
UNC and UNF Thread Repair Kits
UNC thread repair kits are used for coarse inch-thread repairs. Coarse threads are common in many general-purpose fastening applications and are often easier to start in compatible parts.
UNF thread repair kits are used for fine inch-thread repairs. Fine threads have more threads per inch and may be used where a finer adjustment, different engagement, or specific equipment requirement is needed. Match the thread standard to the original fastener and tapped hole.
Stainless Steel Thread Inserts
E-Z Coil kits use stainless steel inserts for thread repair. Stainless steel inserts can provide durable internal threads in compatible repaired parts and are commonly used in maintenance, repair, and equipment applications.
Choose the insert material and kit type based on the base material, fastener material, environment, and repair requirements. Confirm compatibility before using a thread repair kit in critical, high-load, high-heat, or safety-related applications.
E-Z Coil Kits vs Standard Fastener Kits
E-Z Coil kits are thread repair kits, not general screw, nut, bolt, or washer assortments. They are used when the threaded hole itself needs to be repaired before a fastener can be installed.
Standard fastener kits are used when the threaded hole or mating hardware is already usable and replacement fasteners are needed. Choose E-Z Coil kits when the internal threads are damaged, stripped, or worn.
E-Z Coil Kits vs Individual Thread Inserts
E-Z Coil kits are useful when the repair requires inserts plus the matching installation components. A kit can help reduce the chance of ordering inserts without the correct tap or installation tool.
Individual thread inserts may be the better choice when you already have the correct drill, tap, installation tool, and know the exact insert size, length, thread standard, and quantity needed for repeat repairs.
Thread Repair Kits for Maintenance and Shop Use
Thread repair kits are useful for maintenance teams and repair shops because stripped threads can stop equipment repairs, assembly work, or service jobs. Keeping common E-Z Coil kit sizes available can make it easier to repair threaded holes without replacing the entire part.
For shop use, choose thread repair kits based on the fastener sizes and equipment types repaired most often. Keep the kit instructions, tools, and inserts organized so the correct components stay matched together.
How to Choose the Right E-Z Coil Kit
Choose the E-Z Coil kit based on the original thread size, thread standard, thread pitch, inch or metric system, insert material, insert length, thread direction, installation tool, and the material being repaired.
If the damaged thread is an inch size, compare UNC and UNF E-Z Coil kits. If the damaged thread is metric, choose a metric E-Z Coil economy thread repair kit. Always confirm the original fastener size and thread pitch before drilling or tapping the repair hole.

E-Z Coil Kit FAQs
What are E-Z Coil kits?
E-Z Coil kits are thread repair kit assortments used to repair damaged, stripped, or worn internal threads in compatible parts and assemblies.
When should I use an E-Z Coil kit?
Use an E-Z Coil kit when a threaded hole is damaged and needs a threaded insert repair so the correct fastener size can be used again.
What is included in E-Z Coil kits?
E-Z Coil kits may include stainless steel inserts and matching installation components depending on the kit size and style. Check the specific product listing for the exact kit contents.
What is the difference between inch and metric E-Z Coil kits?
Inch E-Z Coil kits are used for inch-threaded repairs such as UNC and UNF sizes. Metric E-Z Coil kits are used for metric-threaded holes and metric fasteners.
What is the difference between UNC and UNF thread repair kits?
UNC thread repair kits are used for coarse inch-thread repairs. UNF thread repair kits are used for fine inch-thread repairs. Match the kit to the original fastener thread.
Are E-Z Coil kits the same as fastener assortment kits?
No. E-Z Coil kits are thread repair kits used to restore damaged internal threads. General fastener assortment kits include replacement screws, nuts, bolts, washers, anchors, or other hardware.
Can I use an E-Z Coil kit without confirming the original thread size?
No. Confirm the original thread size, thread pitch, and thread standard before using a thread repair kit. The insert and tap must match the fastener that will be installed after repair.
How do I choose the right E-Z Coil kit?
Choose the kit based on the original thread size, thread pitch, inch or metric system, UNC or UNF thread standard, insert length, thread direction, installation tool, and the material being repaired.
