V-COIL Wire Thread Insert M 14 x 1.5 - 3.0 D | VÖLKEL
V-COIL Wire thread insert Free running type S M 14 x 1.5 - 3.0 D (50 pcs.)
You select this wire thread insert when you need a repair that restores thread function and keeps the nominal fastener system in service. It supports maintenance and component recovery in housings, machine parts, and other threaded locations where repeat assembly is expected. The designation in the product name defines the repair size and insert length.
The M designation identifies metric ISO threads that are standard across general engineering, maintenance, and machine building. Free running type S means the insert is intended for normal screw running without a self locking prevailing torque function.
- Restore damaged or worn internal threads while keeping the original fastener system in service.
- Reinforce threads in materials with lower shear strength when repeated assembly is expected.
- Recover expensive components during maintenance, overhaul, and small batch rework.
- Use in mechanical engineering, automotive service, fixture repair, and general workshop maintenance.
Note Select the matching STI tap, hole preparation, installation tool, and tang handling method for the stated insert size and length.
- Restores thread function without changing the original screw system.
- Supports higher load distribution than a damaged parent thread alone.
- Compact insert geometry allows repair in existing components without major redesign.
- Stainless wire construction supports corrosion and temperature resistance tendencies.
Drawbacks
- Installation requires the correct repair preparation tools and an oversized STI mounting thread.
- It is not a substitute for correcting cracked parent material or damaged seating faces around the thread.
- Inspect the damaged thread and confirm that the repair size in the product name matches the original fastener system.
- Prepare the hole according to the insert system so the damaged thread area is ready for the oversized STI thread.
- Cut the STI mounting thread with the matching repair tap and keep the tool square to the hole axis.
- Clean the prepared hole so chips, oil residue, and loose material do not interfere with insert seating.
- Drive the insert with the matching installation tool until it sits correctly below the surface and follows the thread path cleanly.
- Remove the tang where the system requires it and then check that the mating screw runs freely in the repaired thread.

- How do you choose the correct insert?
Match the original thread designation, the insert type, and the insert length from the product name to the repair job. Also confirm that the available thread engagement depth suits the selected insert length.
- When do you use free running type S?
Use free running type S when the assembly needs normal screw movement without a prevailing torque locking function from the insert itself.
- Can you use this insert to reinforce softer materials?
Yes. Wire thread inserts are often used to improve thread durability in materials where repeated assembly would wear the parent thread more quickly.
- Where can you read more about wire thread insert types?
Technical information wire thread inserts DIN 8140 as PDF
- What else do you need for installation?
You normally need the matching drill preparation, an STI tap for the mounting thread, an installation tool, and the appropriate tang handling step for the insert system.
- Where can you find the full thread repair catalog?
VC 23 catalog as PDF
- Can you use the repaired thread with the original fastener size?
That is the normal purpose of this system. After correct installation, the repaired thread is intended to accept the original mating thread designation again.
