Bucha de expansão Fischer MS 8 x 28

The Fischer MS 8 x 28 expansion anchor is a brass expansion plug designed to hold a metric thread in solid building materials such as concrete, brick and masonry. It is installed in a pre-positioned hole and secures itself when a screw or threaded rod is driven in, expanding to anchor firmly. Each pack contains 50 pieces and the anchor is suitable for mounting items like shelves, flow heaters and aggregates.

Advantages

The brass construction provides corrosion resistance and reliable long-term performance in solid substrates. The expansion principle allows for a secure grip without the need for additional components. Its compact dimensions (8 mm diameter, 28 mm length) and standardized metric thread compatibility make it suitable for common fastening tasks in construction and repair work.

Suitable for

• Fixing shelves and storage units to concrete or brick
• Mounting flow heaters, small aggregates and piping supports
• General masonry and concrete fastening where a metric thread is required
