Part Number: 777208
This product is part of the Wielander + Schill XSeries professional riveting technology offering, providing high-quality steel blind screw sleeves (also known as threaded inserts) specifically designed for bolted connections. These components offer an ideal solution where a solid, threaded connection point needs to be created on thin sheets or hard-to-reach surfaces.
The primary function of steel blind screw sleeves is to provide durable and reliable threaded connection points for various materials, especially where creating traditional threaded holes is impossible or uneconomical. The product is excellently applicable in the automotive industry, body repairs, metal construction, and general machine manufacturing where a solid fastening is essential.
The design of the sleeves allows the body of the sleeve to spread out behind the workpiece during riveting, thus ensuring a large bearing surface and an extremely strong fixing. The internal M12 thread is suitable for accepting standard screws.
Main Features:
Function: Creation of threaded fixing points required for bolted connections.
Material: Robust steel construction for maximum strength.
Surface treatment: Galvanized coating ensures excellent corrosion resistance, increasing the component's service life.
Packaging quantity: The package contains 5 pieces of blind screw sleeves, ideal for smaller repairs or testing.
The precise dimensioning of the product guarantees compatibility with the appropriate riveting tools and standard M12 screws.

The galvanized coating is crucial for durability. The zinc layer provides excellent protection against corrosion caused by moisture and chemical effects. This is particularly important in applications where fixing points are exposed to the elements or where the structure is used in a humid environment. The steel base material ensures the necessary mechanical strength to safely withstand the tensile and compressive forces exerted by M12 screws.
These blind screw sleeves are optimized for use with the Wielander + Schill XSeries professional riveting systems. Proper installation requires preparing a hole of the correct diameter in the workpiece, then inserting the sleeve and expanding it with the riveting tool. The 15.9 mm outer diameter requires a precise fit in the drilled hole to achieve maximum fixing force.
Important note: The product is an ideal choice for material thicknesses where the full length of the sleeve (23.0 mm) and the deformation during riveting allow for adequate fixing.
