Grainger Self Locking Thread Insert: Thin Wall

This thin-wall thread insert repairs or reinforces tapped holes in metal assemblies, providing a durable 1/4"-28 internal thread with a 3/8"-24 external thread. It is commonly used in automotive, aerospace, and industrial maintenance applications where stripped threads need restoration without replacing the parent component.

The insert has a 1/4"-28 internal thread size (2B fit) and a 3/8"-24 external thread size (2A fit), fine thread type, thin wall design, and inch system. It is compatible with a 3/8"-24 tap and is part of the EZ-313-428 installation kit. The self-locking feature prevents loosening under vibration.

Installation requires tapping the hole to 3/8"-24, then using the EZ-313-428 kit's driver to insert the thin-wall insert until it is flush or slightly below the surface. The self-locking element engages after installation. Follow standard thread insert practices: clean threads, use appropriate lubricant, and verify depth with a gauge.
