Value Collection 22573 Free Running Insert M8 X 1.25

Product Description

The VALUE COLLECTION 22573 is a free running helical wire thread insert designed to create strong, wear-resistant internal threads in parent materials that may be softer or more susceptible to thread damage. The insert measures M8 x 1.25 with a 12 mm overall length, following a 1-1/2D length-to-diameter ratio. Constructed from stainless steel with a bright, uncoated finish, it delivers corrosion resistance and durability in demanding fastening applications. The tanged design allows for controlled installation using a standard insert driver tool. This insert is well suited for maintenance, repair, and manufacturing work across mechanical and industrial trades.

Free running inserts of this type are commonly installed in metalworking, machinery repair, automotive, and general manufacturing environments where stripped or damaged threads need restoration or where a durable threaded interface is required in a softer base material. The M8 x 1.25 metric coarse thread standard makes this insert compatible with a wide range of standard metric fastener assemblies. Installation is performed by machinists, maintenance technicians, and mechanical tradespeople working with tapped holes that require reinforcement or repair.

Key Features

• M8 x 1.25 metric coarse thread for compatibility with standard metric fasteners
• 12 mm overall insert length with a 1-1/2D length-to-diameter ratio
• Tanged design for controlled installation with a standard insert driver
• Stainless steel construction provides corrosion resistance and long-term durability
• Bright, uncoated finish with 7-3/8 free coils for consistent thread engagement

Compatibility

Designed as a standard free running helical wire thread insert for use in any tapped hole meeting M8 x 1.25 metric coarse thread specifications.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a dedicated insert driver sized for M8 x 1.25 thread. The parent material must be drilled and tapped to the correct insert tap size before installation. After the insert is seated to the proper depth, the installation tang is broken off using a tang break-off tool. Ensure the work area is de-energized and all moving parts are secured before performing thread repair on installed assemblies.
