Value Collection 22545 Free Running Insert 7/16-20 Unf

Product Description

The VALUE COLLECTION 22545 is a free running helical wire thread insert designed to restore or reinforce internal threads in metal components. Manufactured from stainless steel with a bright, uncoated finish, this insert installs into a pre-tapped hole to create a strong, wear-resistant threaded engagement. The 7/16-20 UNF thread profile and 0.656-inch overall length make it suitable for precision fastening applications where thread integrity must be maintained. The tanged style is compatible with standard insert installation tooling. Each package contains 10 inserts with a minimum order quantity of 1 package.

Free running thread inserts are commonly used in aerospace, automotive, industrial, and general manufacturing settings where stripped or damaged threads must be repaired or where a softer base material requires a harder mating thread surface. The 1-1/2D length-to-diameter ratio and 10-5/8 free coils provide consistent thread engagement depth. Licensed mechanics, machinists, and maintenance technicians typically install these inserts during component repair or original equipment assembly operations.

Compatibility

Designed as an OEM-style free running helical thread insert for use in pre-tapped holes requiring 7/16-20 UNF thread repair or reinforcement in metal substrates.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician using a dedicated helical insert installation tool sized for the 7/16-20 UNF thread. The receiving hole must be drilled and tapped to the correct insert tap size before installation. After the insert is seated, the tang is broken off using a tang break-off tool. Follow the insert manufacturer's drilling and tapping chart to ensure proper hole preparation and thread engagement.
