0.8 mm Coarse Threaded Inserts

These 0.8 mm coarse threaded inserts are steel fasteners with a yellow zinc finish. They function as blind nut inserts that anchor from one side of a workpiece. The pack contains ten pieces for repair or assembly tasks. They suit mechanics and fabricators who need a permanent internal thread in thin material.

Sustained Load Behaviour

The steel body and yellow zinc coating resist corrosion during extended service. Thread engagement remains consistent when the insert is properly set in metal or plastic. No performance data for vibration or thermal cycling is supplied. Buyers needing certified pull-out or torque values should consult engineering specifications.

Installation Notes

A rivet nut tool is required to collapse the tubular body and lock the insert in place. Access to only one side of the panel simplifies the operation. The process fails if the hole diameter is incorrect or the tool pressure is insufficient. No installation tool or drill bit is included in the pack.

Questions about this item

How much heat or noise do these 0.8mm threaded inserts generate during all-day use?

They are passive steel fasteners with no moving parts, so they produce no heat and no noise once installed.

What installation tool must I already own to use these MFC 39785 inserts?

A rivet-nut setter or compatible hand tool that accepts 0.8 mm coarse-thread mandrels is required.

Will these yellow-zinc inserts gall or corrode when paired with older stainless-steel bolts?

The yellow zinc coating resists corrosion, but dissimilar metals can accelerate galvanic action in wet environments.
