Völkel V‑Coil thread repair kit M8×1 — stainless steel, 20 inserts

The Völkel V‑Coil thread repair kit is a compact repair set designed to restore damaged internal threads to DIN 8140 standard for M8×1 assemblies in stainless steel applications.

• DIN 8140 compliance for standard threads
• Stainless steel inserts for corrosion resistance
• 20 V‑Coil inserts for multiple repairs
• 1.5×D length for reliable thread engagement

Restore thread integrity quickly and reliably

The set is tailored for internal thread restoration where predictable mechanical performance is required. Using V‑Coil wire thread inserts, the original thread dimensions are reproduced and the tensile strength of the joint is maintained. Because the coils are made from stainless steel, repaired threads benefit from improved wear resistance and dimensional stability under load. Repair procedures are shortened compared with full component replacement, which supports uninterrupted production flow and reduces fixture downtime.

Long‑term durability in corrosive or stainless environments

Designed for applications exposed to moisture or corrosive agents, the stainless steel construction ensures that the inserts resist oxidation and retain clamping integrity. The kit conforms to DIN 8140, which standardises thread geometry and fit; this means repaired threads will meet industry tolerances and be compatible with standard bolts and fasteners. For assemblies where corrosion resistance and safety are priorities, the coil inserts provide a consistent, long‑lasting solution that reduces the risk of repeat failures.

Efficient workshop use and cost effective maintenance

Each set contains 20 inserts, enabling multiple repairs without replenishing stock immediately. The inserts’ 1.5×D engagement length provides sufficient thread depth for secure load transmission while keeping material removal to a minimum. Using the kit reduces spare‑part inventories and the time spent on rework, so maintenance cycles are shortened and overall cost of ownership falls. The wire‑insert method is particularly effective where component replacement would be more time consuming or expensive.

Compatibility and technical clarity for procurement

The kit matches standard M8×1 threaded components and is suitable for retrofitting into existing assemblies where the parent material accepts a coil insert. The coil design creates a steel bearing surface inside the parent bore, which is often preferable to cutting new hard threads into softer base metals. Technical staff will recognise the V‑Coil solution as a proven industry method for restoring thread function while maintaining compliance with metric thread standards.
