The Workshop Warehouse Threaded Inserts Regular kit is an essential solution for engineers and DIY enthusiasts who require robust, repeatable fastening in softer materials. These inserts provide superior holding power and structural integrity for components that need to be assembled and disassembled frequently. While this kit offers excellent versatility across five common metric sizes, users should note that these inserts are specifically designed for softer materials and may not be suitable for high-impact metal-on-metal applications.

These are compatible with standard metric bolts corresponding to the M4, M5, M6, M8, and M10 specifications.
While intended for softer materials like plastic or wood, they may work in soft aluminum; however, they are not rated for high-stress structural metal connections.
The complete kit weighs 1kg including the inserts and the storage container.
The kit includes the 250 inserts and the storage box; it does not include installation drivers.
You can clean them with a standard degreaser or wipe them with a dry cloth. Ensure they are completely dry before installation.
The drill hole is likely too large for the insert. Use a slightly smaller drill bit or apply a drop of thread-locking adhesive to the exterior of the insert.
Ensure the pilot hole is perfectly perpendicular to the surface and that the hole is not too tight. You may need to chamfer the edge of the hole slightly to allow the threads to bite.
To install these inserts, first identify the correct drill bit size recommended for the specific metric diameter (M4-M10). Drill a clean, straight pilot hole into your material. Ensure the hole depth is sufficient for the length of the insert to sit flush with or slightly below the surface. Use a manual hex driver or an installation tool to thread the insert into the hole until it is seated firmly. For long-term maintenance, store the container in a dry environment to prevent any surface oxidation on the metal components. If you are working with very brittle plastic, consider a test piece to confirm the drill diameter prevents cracking during insertion.
