This kit is specifically designed for 5/16" x 18 UNC (Coarse) Imperial threads.
The thread inserts are made of stainless steel, providing maximum strength and rust resistance.
No, this kit is exclusively for Imperial threads (5/16" x 18 UNC) and is not compatible with metric thread sizes.
The process involves four main steps: drilling the damaged thread, tapping new threads, installing the insert, and breaking off the tang.
Yes, the kit is designed for both commercial (professional) and occasional home use, featuring durable components.
UNC stands for 'Unified National Coarse', indicating a standard coarse thread pitch for Imperial fasteners.
The kit comes in a blow-molded case, which should be used for organized storage and easy transportation of all the components.
Ensure the hole was drilled to the correct size and the new threads were tapped accurately. Check for debris in the tapped hole or on the insert.
Ensure the tang breaking tool is properly aligned with the tang. Apply firm, steady pressure. If the tang is stubborn, a very slight rotation back with the installation tool might help loosen it before breaking.
Re-evaluate the initial drilling and tapping steps. Ensure the correct size drill bit and tap were used for the 5/16" x 18 UNC specification.
This usually indicates the tapping or drilling was not precise. For critical applications, consider re-drilling and re-tapping if possible, or assess if the insert is sufficiently engaged.
Compatibility: This kit is exclusively designed for repairing 5/16" x 18 UNC (Coarse) Imperial internal threads. It is not compatible with metric threads or other imperial thread sizes.
Setup and Use:
Care: Store all components in the provided blow-molded case to prevent loss and damage. Keep the drill bit and tap clean and dry to prevent rust. Inspect inserts for any damage before use. Clean any debris from the tools after use.
