Value Collection 22575 Free Running Insert M12x1.75 5pk

Product Description

The VALUE COLLECTION 22575 is a tanged, free-running helical wire thread insert designed to create strong, wear-resistant internal threads in parent materials that require reinforcement or thread repair. Manufactured from stainless steel with a bright, uncoated finish, this insert accepts an M12 x 1.75 metric coarse thread and measures 18 mm in overall length. The length-to-diameter ratio is 1-1/2D, and the insert features 8-1/4 free coils. It is installed using a standard installation tool compatible with M12 helical inserts. Machinists, maintenance technicians, and assembly professionals use this insert in both production and repair applications.

This insert is suited for use in metals, plastics, and composite materials where thread strength must exceed what the base material can provide on its own. Common applications include thread repair on stripped or damaged bores, thread installation in soft or thin-walled materials, and thread reinforcement in high-stress assemblies. The metric coarse M12 x 1.75 specification makes this insert appropriate for a wide range of industrial, automotive, and equipment maintenance scenarios. Each package contains 5 inserts.

Key Features

• M12 x 1.75 metric coarse thread for broad industrial compatibility
• 18 mm overall length at a 1-1/2D length-to-diameter ratio
• 8-1/4 free coils for consistent spring tension during installation
• Tanged design works with standard helical insert installation tools
• Stainless steel construction resists corrosion in demanding environments
• Bright, uncoated finish for consistent dimensional tolerances

Compatibility

Designed as an OEM-style replacement or production insert for any application requiring a free-running M12 x 1.75 metric coarse helical thread insert with an 18 mm overall length and tanged design.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a mandrel-style helical insert tool sized for M12. The parent bore must be drilled and tapped to the correct insert tap size before installation. After the insert is driven to the proper depth, the tang is removed using a tang break-off tool. Always verify the parent material thread specification before selecting insert length.
