M8-1.25 Blind Nut Insert Pack
This pack contains six steel blind nut inserts with an M8 thread and a 1.25 mm pitch. Each insert is a one-piece tubular rivet that provides a permanent female thread in thin or hollow materials. The zinc yellow finish adds corrosion resistance for indoor and outdoor use. Installation is completed from a single side using a suitable rivet-nut tool.
Suitable for sheet-metal.
These inserts suit maintenance, automotive and fabrication tasks where rear access is impossible. They create load-bearing threads in materials too thin for tapping. Builders who need a different thread size, a larger grip range or a stainless steel option should look at alternative inserts.
M8-1.25 thread size and pitch
The M8-1.25 metric coarse thread is the critical specification that determines bolt compatibility. Verify that the mating fastener matches this diameter and pitch before purchasing. The pack quantity of six pieces is also fixed for this part number.

Questions about this item
How much force or heat does the M8-1.25 blind nut insert generate during all-day installation work?
The insert itself produces no heat or noise; it is a passive steel fastener that only requires a manual or pneumatic setting tool to compress the body from one side.
What setting tool must I already own to install these M8-1.25 rivet nuts?
You need a rivet-nut tool with an M8-1.25 mandrel, either a hand lever style or a pneumatic gun, to pull the insert and form the blind-side flange.
Will the zinc-yellow finish on these M8-1.25 inserts react with older steel panels I am repairing?
The zinc-yellow coating is compatible with standard mild steel; it provides sacrificial corrosion protection and will not cause galvanic issues on typical automotive sheet metal.
