Value Collection 22543 Free Running Insert 5/16-24 Unf

Product Description

The VALUE COLLECTION 22543 is a free-running helical wire thread insert designed to repair or reinforce internal threads in parent materials that require a durable, corrosion-resistant fastening solution. With a 5/16-24 UNF thread size and an overall length of 0.469 inches, this insert follows a 1-1/2D length-to-diameter ratio and features a tanged design for standard installation tooling. Manufactured from stainless steel with a bright, uncoated finish, it provides reliable thread reinforcement in applications where thread stripping or wear is a concern. Each package contains 10 inserts.

Free-running helical thread inserts are used across industrial, mechanical, and maintenance applications where restoring or strengthening threaded holes in aluminum, cast iron, magnesium, or other soft parent materials is required. The tanged design is compatible with standard wire thread insert installation tools. Typical install scenarios include equipment repair, aerospace and automotive component maintenance, and general machining work where original threads have been damaged or undersized for the intended fastener load.

Key Features

• 5/16-24 UNF thread size for compatibility with fine-thread fastener applications
• 0.469 inches overall length at a 1-1/2D length-to-diameter ratio
• Tanged design works with standard helical insert installation drivers
• Stainless steel construction resists corrosion and withstands mechanical stress
• Bright, uncoated finish with 8-7/8 free coils per insert
• Sold in a pack of 10 inserts

Compatibility

Designed as a standard free-running helical thread insert for use in any parent material tapped to accept 5/16-24 UNF wire thread inserts with a 1-1/2D insert length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a dedicated helical insert installation tool sized for 5/16-24 UNF. Ensure the parent material is drilled and tapped to the correct insert tap size before driving the insert to the proper depth. After installation, remove the tang using a tang break-off tool per standard wire thread insert procedure. Refer to applicable shop standards and the insert manufacturer guidelines for tap drill sizing and installation depth requirements.
