Threaded Insert FANAR VC-07621 M12x1.75 3.0D

FANAR threaded insert VC-07621 provides an internal M12x1.75 metric thread with a length of 3.0D. It is engineered to form or reinforce durable metal threads in softer base materials, offering a reliable solution for repair, assembly and reinforcement tasks. The insert is suitable for situations where restoring thread strength or creating new serviceable threads is necessary in components used in mechanical assemblies and fixtures.

Advantages

The threaded insert delivers consistent thread dimensions and improved load-bearing capacity compared with direct tapping in soft metals or plastics. Its design reduces wear on the parent material, increases resistance to stripping and enables repeated assembly and disassembly cycles without degrading the threaded connection. The compact 3.0D length balances thread engagement and space efficiency.

Suitable for

• Repairing stripped or damaged threads in softer metals and composite components
• Creating new, serviceable threads in machine housings, fixtures and panels
• Strengthening threaded connections subject to frequent tightening or vibration
• Industrial maintenance and metalworking applications requiring durable internal threads

Key specifications

• Internal thread size: M12 x 1.75
• Length: 3.0D (three times the nominal thread diameter)
• Material type: metal insert designed for installation in softer substrates
• Functional purpose: thread reinforcement and creation of serviceable internal threads

How to use

Drill or ream the host material to the appropriate hole diameter for the insert, following standard drill size recommendations for an M12x1.75 insert of 3.0D length. Prepare the hole by removing debris and ensuring correct alignment. Install the insert using the recommended installation tool or method for the insert type, applying steady axial pressure until fully seated. If required, use a locking or setting method appropriate for the substrate and application to secure the insert in place.

Usage recommendations

When installing into softer metals or composite materials, verify hole tolerance and cleanliness before insertion. For high-vibration environments, consider using a locking feature or appropriate adhesive in combination with the insert to prevent loosening. Always follow torque specifications for M12x1.75 fasteners to avoid over-torquing and ensure optimal thread life.
