## Summary description

Niczuk brass expansion sleeve M8 x 30 (model 1440008000) is a threaded insert designed for creating a durable M8 internal thread in thin-walled materials. Made of brass, the expandable sleeve secures into a drilled hole and expands to lock the thread, providing reliable fastening for machinery, furniture fittings, and repair tasks in metal, plastic or composite panels.

## Long description

Niczuk brass expansion sleeve M8 x 30 is a threaded insert engineered to create a durable M8 internal thread in thin-walled materials. Manufactured from brass, the expansion sleeve is installed into a pre-drilled hole and expands to lock in place, forming a solid threaded anchor that restores or provides reliable fastening points in metal, plastic or composite panels. The product is suitable for assembly, maintenance and repair tasks where a strong internal thread is required but base material thickness is limited.
Advantages
The brass construction offers good corrosion resistance and electrical conductivity while remaining easy to machine. The expandable design ensures a secure mechanical interlock with the host material, distributing load across the sleeve for increased pull-out strength compared with direct tapping in thin sheets. The M8 internal thread and 30 mm sleeve length provide a balance between engagement depth and compatibility with common fasteners used in machinery, furniture fittings and repair applications.
Suitable for
Creating or repairing M8 threaded points in thin metal sheets
Installing fasteners in plastic panels and composite boards
Furniture assembly and fittings where reinforced threads are required
Mechanical repairs and maintenance on equipment with thin-walled components
Key specifications
Thread size: M8 internal thread
Sleeve length: 30 mm
Material: brass
Expandable sleeve type for mechanical locking in host material
Intended for use in thin-walled materials such as metal, plastic and composites
How to use
Drill a hole of the appropriate diameter into the host material following the manufacturer's recommended hole size for an M8 expansion sleeve. Insert the sleeve into the hole so it sits flush or to the required depth, then use the specified mandrel or driver to expand the sleeve until it mechanically locks against the material. After expansion, install an M8 bolt or screw into the internal thread to complete the fastening. Ensure alignment and cleanliness of the hole before installation to achieve correct expansion and optimal load-bearing performance.
Usage recommendations
Use the sleeve in materials with sufficient surrounding thickness to allow full expansion without cracking. For corrosive environments or dissimilar-metal assemblies, consider compatibility of brass with mating materials and, if necessary, apply appropriate coatings or isolation layers. Follow torque specifications for M8 fasteners to avoid overloading the sleeve and base material.
