The Tolsen 54288 is a heavy duty shell anchor designed for creating secure fastenings in concrete, brick, or other hard substrates. It consists of a bolt and a sleeve, featuring an M10 thread diameter and a 14 mm sleeve diameter across a total length of 100 mm. To prevent corrosion and extend the life of the fastener, the components are finished with a galvanized surface. This makes it a reliable choice for those needing to mount heavy equipment or structures where a strong, permanent grip in masonry is required.
