V-COIL thread insert DIN 8140 — M4 x 0.7, stainless steel, 1.5×D

The V-COIL thread insert DIN 8140 is a free-running helical coil designed to restore and reinforce internal threads in light to medium-duty assemblies, meeting industry tolerances for reliable mechanical fastening

• Free-running helical insert to DIN 8140
• Stainless steel for corrosion resistance
• ISO 2 (6H) tolerance for precise fit
• Nominal length 1.5×D for secure engagement

Reliable thread reinforcement for durable assemblies

A helical thread insert provides a practical way to repair worn or damaged threads and to strengthen new female threads where base materials are softer than the fastener. The use of a stainless steel coil distributes clamping loads more evenly than direct tapping into the parent material, reducing local stress and increasing joint longevity. Specified for M4 x 0.7, this solution is suitable where consistent clamping force and repeatability matter in production and maintenance environments.

Standard conformity that simplifies design and inspection

Compliance with DIN 8140 and a declared tolerance of ISO 2 (6H) gives clear dimensional expectations and simplifies quality checks during incoming inspection. The specified tolerance class ensures a defined internal thread fit for common metric fasteners, reducing ambiguity in drawing specifications and easing interchangeability. For procurement and engineering teams, this standardised approach saves time in design validation and supports predictable assembly performance.

Material selection for environmental resistance

Manufactured from stainless steel, the insert offers enhanced corrosion resistance compared with untreated inserts, which is particularly valuable for components exposed to humidity or mild corrosive atmospheres. The metallic composition also preserves mechanical properties at fastening points and is compatible with common fastener materials, helping to avoid premature wear without compromising clamp integrity.

Efficient packaging and consistent installation performance

Delivered as a pack of 100, the coils are pre-sized to a nominal length of 1.5×D, providing sufficient engagement depth for M4 fasteners while keeping installation simple and repeatable. The free-running design facilitates insertion and alignment during assembly or repair tasks, reducing cycle time on workbenches and in service operations. For workshops and production lines, bulk packaging supports uninterrupted workflow and consistent component handling.
