Value Collection 43030 Knurled Threaded Insert M4x0.70

Product Description

The VALUE COLLECTION 43030 is a knurled body open end threaded insert designed to create strong, permanent internal threads in materials that cannot accept a standard tapped hole. The insert features an M4x0.70 thread size and a 6.73mm insert diameter, with an overall length of 10.67mm. Manufactured from 1008/1010 steel with a clear protective zinc yellow dichromate finish, it provides corrosion resistance and mechanical durability in light-duty fastening applications. The knurled outer body resists rotation once pressed into the mating hole, and the open end design allows thread engagement from both directions. Machinists, tool and die technicians, and maintenance professionals install these inserts in sheet metal, thin-walled parts, and assemblies requiring reliable threaded connections.

This threaded insert is suited for use in sheet metal fabrication, light structural assemblies, and repair applications where parent material threads have been stripped or where thin stock cannot support a direct tap. The required installation hole diameter is 6.75mm, and the head diameter measures 9.91mm. These inserts are typically installed using a press or insertion tool and are appropriate for both production and MRO environments where M4 thread engagement is needed in thin or soft base materials.

Key Features

• M4x0.70 internal thread provides standard metric fastening compatibility
• Knurled outer body locks against rotation after installation in a 6.75mm hole
• Open end design allows full thread-through engagement
• 1008/1010 steel construction for reliable mechanical strength
• Zinc yellow dichromate finish provides clear protective corrosion resistance
• 9.91mm head diameter seats flush against the work surface for a clean install

Compatibility

Designed as a standard knurled body open end press-in threaded insert for use in sheet metal and thin-walled components requiring an M4x0.70 internal thread with a 6.75mm installation hole.

Installation Notes

Installation is performed using an arbor press or dedicated insertion tool aligned perpendicular to the workpiece surface. Power down and de-energize any assembly before installing inserts into live equipment panels or enclosures. Verify the hole diameter is maintained at 6.75mm for proper retention of the knurled body. Do not hammer inserts in freehand, as misalignment can damage the thread form or distort the parent material.
