Heritage Brass Black Iron Flat Bolts

The Heritage Brass Black Iron Flat Bolt collection by M Marcus provides a practical door-fastening option with a simple, understated appearance. Made from black iron and finished in Matt Black, these bolts are offered with two backplate lengths to suit different requirements. The flat profile and dark, low-sheen finish work naturally with both contemporary and heritage-style interiors.

Choose between 6-inch and 8-inch flat bolts

The main difference across this range is the backplate length. Checking the available fitting area and the proportions of the door will help you select the appropriate version:

• 6-inch flat bolt: the shorter option in the collection.
• 8-inch flat bolt: a longer version with an 8-inch backplate.

Both sizes share the same Black Iron design and Matt Black finish, making it straightforward to use a consistent style where different bolt lengths are needed. The smooth matt surface keeps the appearance restrained, while the flat silhouette complements other black architectural hardware.

Each listed product contains one bolt together with fixing screws and fasteners. Before ordering, compare the chosen 6-inch or 8-inch backplate size with the intended fitting position and allow for the surrounding door hardware.
