Description
Overview:
The Mason Mate Sleeve Anchor - Loose Bolt, M12 x 100, is a steel expanding fixing for secure fastening into masonry. It features a slotted sleeve and cone that expand inside the hole as the hex bolt is tightened, locking the anchor in place. Zinc and yellow passivation adds corrosion resistance for long service life. Designed for through-fixing, it is suitable for most solid substrates including concrete and brick. The M12 diameter (12 mm) provides a robust hold, while the 100 mm length suits medium-duty brackets, base plates, and frames. Commonly installed with an SDS or percussion drill and tightened with a standard spanner or socket. Supplied in a pack of 25, it is a practical choice for trades and DIY users across building, workshop, and maintenance tasks.
