V‑Coil Thread Repair Kit M4x0.7 (DIN 8140) — Stainless Steel, 1.5xD

V‑Coil Thread Repair Kit M4x0.7 for workshop and maintenance use, designed to restore damaged M4 threads with stainless‑steel inserts to the original thread form and strength

• Stainless‑steel V‑Coil inserts
• DIN 8140‑compliant repair system
• Includes 20 thread inserts

Repair threads quickly while maintaining original strength

The V‑Coil system provides a straightforward way to re‑establish stripped or damaged M4 threads. By installing a precisely formed coil insert into a correctly sized pilot hole, the original thread geometry and load‑bearing surface are effectively restored. The M4x0.7 size, combined with a 1.5xD insert length, delivers a balance between engagement length and compact installation, making the repair both robust and space‑efficient. For workshops seeking predictable outcomes, the coil method reduces the need for oversized fasteners and preserves component tolerances.

Proven conformity and dependable batch performance

Compliance with DIN 8140 ensures that each insert meets recognised dimensional and material criteria, which supports interchangeability and simplifies quality checks. The kit contains 20 inserts, enabling multiple repairs or stocking for routine maintenance tasks. Using stainless‑steel components improves resistance to corrosion and mechanical wear, which is particularly valuable in environments prone to humidity or mild chemical exposure. This predictable durability contributes to lower rework rates and steadier production uptime.

Practical suitability for maintenance and light industrial applications

The set is conceived for general workshop use and scheduled maintenance, where restoring threaded joints is preferable to component replacement. The V‑Coil inserts are suitable wherever M4 threads are required to regain original specification without changing mating parts. Installation requires standard coil insertion tooling and the correct tap size for the pilot hole; when applied correctly, the repair achieves consistent clamping performance and prolongs service life. For procurement and stock planning the compact kit format simplifies inventory management in maintenance stores.
