Heli-coil A4184-10CNW150 Screw-locking Insert M10 1.50

Product Description

The HELI-COIL A4184-10CNW150 is a tangless screw-locking helical wire insert designed to repair or reinforce threaded holes in parent materials that require a secure, vibration-resistant fastening point. Manufactured from Grade 304 stainless steel with a dry film lubricant finish, this insert provides corrosion resistance and controlled locking torque in demanding service environments. The M10 x 1.50 metric coarse thread profile and 15 mm overall length place it at a 1-1/2D length-to-diameter ratio, making it well suited for applications where standard thread depth is available and pull-out resistance is a priority. Licensed mechanics, maintenance technicians, and precision assembly workers install this type of insert routinely.

This insert is used across a wide range of industrial, mechanical, and MRO applications including engine repair, equipment maintenance, and structural assemblies where host material threads have stripped or where new thread reinforcement is required. The tangless design eliminates the need for a tang break-off step after installation, reducing debris risk inside blind holes and simplifying the installation process. It is appropriate for use in aluminum, cast iron, magnesium, and other materials where thread strength must match or exceed that of the parent body.

Key Features

• Tangless design eliminates post-installation tang removal and reduces debris in blind bores
• Grade 304 stainless steel construction provides corrosion resistance in wet or harsh environments
• Dry film lubricant finish supports controlled installation torque and consistent seating
• Maximum locking torque of 10.00 Newton-meters with a minimum breakaway torque of 1.4 Newton-meters for vibration-resistant thread locking
• M10 x 1.50 metric coarse thread, 15 mm overall length, 1-1/2D ratio
• 8 free coils provide uniform load distribution across the engaged thread length

Compatibility

Designed as an OEM-style thread repair and reinforcement insert for tapped holes with M10 x 1.50 metric coarse internal threads requiring a 1-1/2D insert length.

Installation Notes

Installation requires a HELI-COIL or compatible tangless insert installation tool sized for M10 x 1.50 metric coarse thread. The parent material must be drilled and tapped to the correct STI (Screw Thread Insert) tap size before insert installation. Power down or de-energize any equipment before performing thread repair on functional assemblies. Do not use standard tang-style installation tools with tangless inserts, as this can damage the insert or the parent thread.
