Value Collection 22546 Free Running Insert 1/2-20 Unf

Product Description

The VALUE COLLECTION 22546 is a free running, tanged wire thread insert designed to restore or reinforce internal threads in metallic and non-metallic workpieces. With a 1/2-20 UNF thread size and an overall length of 0.75 inches, this insert is manufactured from stainless steel with a bright, uncoated finish. The coiled design features 12-3/8 free coils and a 1-1/2D length-to-diameter ratio, providing secure thread engagement once installed. Machinists, maintenance technicians, and assembly professionals install these inserts to convert or repair damaged tapped holes to a standard thread form.

This insert is suited for applications where thread repair or thread reinforcement is required in parent materials that may be softer than the fastener material. Common installation scenarios include repair of stripped threads in aluminum, magnesium, or cast iron components across industrial, automotive, and general maintenance environments. The tanged design is compatible with standard tang break-off tools after installation. Each package contains 10 inserts, making it practical for batch repair jobs or stocking in a shop environment.

Key Features

• Thread size 1/2-20 UNF for compatibility with unified fine thread fasteners
• Overall length of 0.75 inches with a 1-1/2D length-to-diameter ratio for solid thread engagement
• Stainless steel construction for corrosion resistance in demanding environments
• Tanged design for installation with standard wire thread insert drivers and tang break-off tools
• 12-3/8 free coils providing consistent thread form across the full insert length
• Bright, uncoated finish — no surface treatment to interfere with thread tolerances

Compatibility

Designed as a standard free running wire thread insert for use in tapped holes requiring 1/2-20 UNF thread form repair or reinforcement across industrial and general maintenance applications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a wire thread insert driver sized for 1/2-20 UNF inserts. The parent hole must be drilled and tapped to the appropriate insert tap size before installation. After driving the insert to the correct depth, use a tang break-off tool to remove the installation tang. Power down or de-energize any associated equipment before performing thread repair work on components that are part of an active system.
