Value Collection 22516 Free Running Insert 1/2-13 Unc

Product Description

The VALUE COLLECTION 22516 is a free-running, tanged helical thread insert designed to repair or reinforce 1/2-13 UNC threaded holes in metal, composite, and other base materials. With an overall length of 0.75 inches and a 1-1/2D length-to-diameter ratio, this insert restores worn or damaged threads to full load-bearing capacity. Constructed from stainless steel with a bright, uncoated finish, it delivers corrosion resistance suitable for demanding service environments. Installation requires a standard tang break-off tool after the insert is driven to depth. This package contains 10 inserts.

Free-running threaded inserts of this type are used across a wide range of applications including machinery repair, equipment manufacturing, automotive service, and structural assemblies where a stripped or weak threaded hole must be brought back to specification. The 1/2-13 UNC thread size is one of the most common fastener standards in North American trade work, making this insert a practical stock item for maintenance, repair, and operations (MRO) use in shops and field service kits.

Compatibility

Installation Notes

Installation should be performed by a machinist, maintenance technician, or qualified trade professional using a proper helical insert installation tool sized for 1/2-13 UNC. The parent hole must be drilled and tapped to the correct insert tap size before driving the insert. After the insert is flush or one turn below the surface, use a tang break-off tool to remove the installation tang. Do not attempt to drive the insert with an improvised tool, as this can damage the coil geometry or the parent material threads.
