V-COIL Thread Repair Kit DIN 8140 M5–M12, Stainless Steel, 1.5×D

V-COIL Thread Repair Kit DIN 8140 M5–M12 is a stainless‑steel insert system for restoring and reinforcing metric threads in damaged or worn components across workshop and industrial applications

• V-COIL system for durable thread restoration
• Stainless steel inserts, corrosion-resistant
• Conforms to DIN 8140 standard
• Coverage from M5 to M12, 1.5×D engagement

Restore stripped threads quickly to avoid production stops

The V‑COIL Thread Repair Kit offers a pragmatic repair method that restores worn threads to specification, reducing the need for part replacement and downtime. The helically wound thread insert is engineered to re‑establish a precise internal thread profile for sizes M5–M12, delivering a repeatable fit. Using a 1.5×D engagement length increases contact area and improves pull‑out resistance, which is vital when parts are subject to repetitive assembly or elevated loads.

Consistent, measurable performance in line with standards

The kit is manufactured in stainless steel and designed to meet DIN 8140, ensuring consistent geometry and tolerance adherence for replaced threads. The V‑shaped coil geometry converts shear stresses into compressive contact over the parent material, enhancing load distribution and fatigue resistance compared with makeshift repairs. Where specification conformity matters, this standard alignment simplifies inspection and documentation in maintenance records.

Practical benefits for workshop and maintenance teams

Adopting this insert system streamlines repairs without extensive rework: worn bores are reinstated with repeatable torque acceptance and reduced scrap rates. The robust construction supports applications that demand corrosion resistance and a durable mating surface. For complex assemblies or high‑value components, technical guidance is available from Metav Werkzeuge to help select the correct insert size and installation technique, supporting efficient maintenance planning and documentation.

Long‑term reliability backed by dependable supply

Made from corrosion‑resistant materials, the inserts provide a durable solution that helps extend component life and lower life‑cycle costs through fewer part replacements. Metav’s emphasis on accessible precision and supply reliability ensures that this V‑COIL solution can be sourced and supported consistently. Confidence in ongoing availability and technical support further reduces operational risk in scheduled and unscheduled maintenance activities.

FAQ

What thread sizes are covered by this kit?
The V‑COIL thread repair assortment covers internal threads from M5 to M12, providing a standardised repair range for common metric thread sizes.

Is the insert material suitable for corrosive environments?
Yes, the inserts are made from stainless steel, offering enhanced corrosion resistance suitable for workshop and many industrial environments where oxidation must be minimised.

What does the 1.5×D engagement specification mean?
The 1.5×D indicates the insert’s engagement length relative to the nominal thread diameter, providing increased contact area and improved pull‑out strength compared with shorter engagements.

Does the system conform to recognised standards?
This repair assortment is produced in accordance with DIN 8140, ensuring predictable geometry and compatibility with inspection procedures that reference this standard.

Can this insert restore the original thread strength?
The V‑COIL design restores functional thread performance and typically improves load distribution by converting shear into compressive contact across the parent material, yielding a robust joint for repeated assemblies.
