Heli-coil A1084-10CN100 Free Running Insert M10 X 1.5

Product Description

The HELI-COIL A1084-10CN100 is a tanged, free running wire thread insert designed to create strong, wear-resistant metric threads in parent materials that are softer or more susceptible to thread damage. Manufactured from 304 stainless steel with a bright, uncoated finish, this insert measures M10 x 1.5 thread size with an overall length of 0.3937 inches (10 millimeters), placing it in the 1D length-to-diameter ratio category. It features 4-7/8 free coils and is installed using a standard installation driver. Machinists, maintenance technicians, and assembly professionals use this insert to repair stripped threads or reinforce new bores in production and field-service applications.

This insert is suited for metric coarse thread applications across a wide range of industries including aerospace, automotive, industrial machinery, and general manufacturing. It is commonly installed in aluminum, cast iron, magnesium, and other materials where the parent thread would not hold up to repeated fastener engagement under load. The tanged design allows the insert to be driven in with a standard tang-break tool after installation.

Key Features

• M10 x 1.5 metric coarse thread size for high-strength thread repair or reinforcement
• Overall insert length of 10 millimeters (0.3937 inches) at a 1D length-to-diameter ratio
• 304 stainless steel construction resists corrosion and withstands elevated temperatures
• Tanged design for positive installation driver engagement; tang breaks off flush after seating
• Bright, uncoated finish with 4-7/8 free coils for consistent spring tension and thread engagement

Compatibility

Designed as an OEM-style free running wire thread insert for metric coarse threaded bores requiring M10 x 1.5 thread repair or new-thread installation in production or maintenance applications.

Installation Notes

Installation is performed using a compatible HELI-COIL installation driver sized for M10 x 1.5 inserts; the bore must be drilled and tapped with the correct HELI-COIL STI tap before the insert is driven in. Power down all equipment and secure the workpiece before beginning thread preparation. After the insert is fully seated, use a tang-break tool to remove the drive tang; ensure the tang is fully removed from blind holes before the fastener is installed. Follow applicable shop procedures and fastener specifications for final torque requirements.
