Our Self Colour Steel Hexagon Full Nuts with BA Thread are presented in a natural self‑colour finish, these fasteners come as they are—no extra coatings, just the raw, industrial charm of steel which is ideal for welding or custom finishes. The hexagon shape ensures an effortless fit with standard sockets and spanners, making installation smooth and efficient.

A defining feature of this product is its BA thread. BA, which stands for British Association, is a traditional thread form known for its distinct V-shaped profile and fine pitch. This thread design is particularly favoured in applications where space is limited and precise, secure fastening is critical—think of vintage equipment restoration or modern engineering projects that require that classic British standard.
