Thread Repair Kits, Metric Fine
Features
- Helicoil thread repair kits are used to repair stripped threads & create new threads for fastening applications.
- These kits include drill bits, steel taps, installation tools and Helicoil inserts.
- Drill bits can attach to hand drills for drilling out holes of required dimensions in metallic materials.
- Taps are used to create threadings on drilled out holes.
- These taps are made of high-speed steel for structural strength to resist bending / breaking under harsh use.
- Helicoil threaded inserts provide stronger threading as compared to the original tapped threaded hole, while preventing thread wear.
- These Helicoil threaded inserts come in metric & imperial sizes, and coarse & fine variants.
- They are made of stainless steel for corrosion resistance & durability.
Working Mechanism
- Select a drill from Helicoil thread repair kits according to the length of Helicoil insert, screw or bolt, to drill out the damaged threading.
- Use an appropriately sized tap (supplied with Helicoil thread repair kits) to re-thread the drilled out hole in the material.
- Select a thread insert and use the supplied installation tool to wind the insert into the hole.
- Use tang break-off rod or punch to remove the tang and allow free passage of bolts. Large-sized holes or spark plug inserts require long nose pliers to bend the tang in & out alternately until the tang breaks free.
- The repaired threaded hole is ready for fastening applications.
Standards and Approvals
- ISO 9001
- QS 9000
Frequently Asked Questions
What are some troubleshooting solutions to Helicoil thread repair kit installation problems?
- If there is a problem while installing a Helicoil thread insert, first match the insert with its correct tap & drill size and then check for wear on them. Helicoil thread plug gages may also be used to check the tapped holes before installing the insert.
- If Helicoil insert installs perfectly, but there is a problem in winding the mating fastener, match the fastener's dimensions with the diameter & pitch of the installed Helicoil thread insert.
Can Helicoil inserts of Helicoil thread repair kits be removed once installed?
Yes, Helicoil offers removal tools for removing installed Helicoil inserts by attaching to them & unwinding them in direction opposite to that of installation.
What are some compatible accessories that can be used along with Helicoil thread repair kits?
Raptor Supplies offers locking thread inserts that lock a fastener once installed and prevent accidental rotational spin outs due to vibrations or torque. We also supply replacement free running inserts and compatible Helicoil repair kit components / tools for replacing old, worn-out or damaged parts and providing efficient operation.
Why are Helicoil inserts larger in diameter than the tapped hole before installation?
Diameter of Helicoil thread inserts is slightly larger than the tapped hole diameter before installation as the installation tool reduces the diameter of the leading coil when it applies torque to Helicoil insert's tang, thereby allowing the insert to enter the tapped hole. After installing Helicoil threaded insert, its high tensile stainless steel coil acts like a spring and expands outward onto the metallic material for a strong anchoring connection.
