Heli-coil A4184-10CN200 Screw-locking Insert M10 X 1.50

Product Description

The HELI-COIL A4184-10CN200 is a tangless, screw-locking helical wire insert designed to create strong, reusable internal threads in parent materials that require reliable thread locking without the use of a separate locking element. Built from Grade 304 stainless steel with a bright finish, this insert measures M10 x 1.50 metric coarse and carries a 2D length-to-diameter ratio with an overall length of 20 mm. The tangless design eliminates the tang-removal step after installation, reducing labor time. Maximum locking torque is 10.00 N/m and minimum breakaway torque is 1.40 N/m. Machinists, maintenance technicians, and assembly professionals install these inserts in metalworking and repair applications.

This insert is suited for both OEM manufacturing and MRO repair work where metric coarse M10 x 1.50 threads must be locked or restored. The tangless configuration makes it compatible with automated and high-volume installation tooling, as well as standard manual insert drivers. Grade 304 stainless steel construction makes it appropriate for corrosion-resistant assemblies in industrial, marine, and mechanical environments where thread integrity under vibration is a requirement.

Key Features

• Tangless design eliminates the post-installation tang-removal step, reducing assembly time
• Grade 304 stainless steel construction provides corrosion resistance in demanding environments
• M10 x 1.50 metric coarse thread with 2D length-to-diameter ratio for secure thread engagement
• Maximum locking torque of 10.00 N/m with minimum breakaway torque of 1.40 N/m
• Bright finish with minimum outside diameter of 11.95 mm and maximum outside diameter of 12.50 mm
• 11-1/8 free coils provide consistent locking performance across the insert length

Compatibility

Designed as an OEM-style screw-locking insert for parent material bores tapped to accept M10 x 1.50 metric coarse helical inserts with a 2D length-to-diameter ratio. Verify parent bore tap size per HELI-COIL installation specifications before ordering.

Installation Notes

Installation requires a HELI-COIL tangless insert driver matched to the M10 x 1.50 thread size. The parent bore must be pre-tapped with the correct STI (Screw Thread Insert) tap prior to installation. Power down or de-energize any equipment before performing thread repair on assemblies in service. Do not use standard tap sizes in place of STI taps, as this will result in improper insert seating and thread failure.
