## Long description

Koelner claw nuts 4x8 mm, pack of 20 are small threaded fastening elements designed for secure attachment in thin sheet metal, panels and chassis where a low-profile nut is required. Each 4x8 mm nut has inward-pointing claws that dig into the substrate to prevent rotation and loosening, providing a removable yet stable threaded connection for repair, assembly and mounting tasks.
Advantages
These Koelner claw nuts combine compact dimensions with a clawed design that increases hold in thin materials without the need for additional welding or rivets. Their low profile suits confined spaces and helps maintain a flat external surface. The set format of 20 pieces ensures enough units for small jobs or maintenance kits, reducing the need for repeated purchases.
Suitable for
Fastening in thin sheet metal and panels

Key specifications
Nut dimensions: 4 x 8 mm
Clawed design for bite into thin substrates
Threaded internal bore suitable for compatible screw sizes
Low-profile form factor for confined spaces
Pack quantity: 20 pieces
How to use
Select a compatible screw that matches the internal thread and the material thickness. Position the claw nut on the prepared hole in the sheet metal or panel so the claws face the material. Press the nut firmly until the claws engage the substrate; light tapping with a hammer on a padded surface can help ensure full engagement if required. Insert and tighten the mating screw to create a secure threaded connection. For removal, back out the screw and pry the claw nut out, taking care not to damage the surrounding material if reuse is intended.
Usage recommendations
Use these claw nuts in materials of appropriate thickness where the claws can bite securely; excessively thick or very soft materials may not provide reliable holding. For critical or high-vibration applications consider using locking features or periodic inspection. Store the pack in a dry place to avoid corrosion and keep spare nuts for maintenance needs.
