Bosch Staples for pneumatic tools - Narrow Crown Staple TK40 25G

These narrow crown staples are primarily used for interior fitting applications, especially where a discreet finish is desired, such as in upholstery, picture framing, and decorative trim work.

The staples are galvanized for corrosion protection, making them suitable for dry interior environments. For prolonged outdoor exposure or high-moisture areas, they may not offer sufficient long-term protection.

These staples are specifically designed for use with the Bosch Pneumatic Stapler GTK 40 Professional.

'Narrow crown' refers to the width of the staple's top bar (the crown). A narrow crown means the bar is thinner, making it less visible on the surface, which is ideal for aesthetic applications.

Each pack contains 5000 staples.

The chisel point ensures a sharp, clean entry into the material, reducing the risk of splitting the wood and providing a more precise fastening.

While technically possible if dimensions match, it is strongly recommended to use these staples only with the specified Bosch GTK 40 Professional stapler to ensure proper function, performance, and avoid tool damage.

Check air pressure on your pneumatic stapler. Ensure it is set to the recommended PSI for these staples. Also, verify the staple length is appropriate for the wood density and thickness.

Ensure the correct staple size (1.2/18g, 25mm) is being used. Clean the staple magazine and driving channel of any debris or bent staples. Check if the stapler is designed for this specific staple type.

This may indicate insufficient driving power (check air pressure) or that the wood is too hard for the staple length. Ensure the chisel point is aligned correctly with the wood surface.

While galvanized, prolonged exposure to high humidity or moisture can still cause surface corrosion. Store staples in a dry environment. If minor surface rust is present, it may not affect performance but prolonged exposure should be avoided.
