What is BS 57 – B.A. screws bolts and nuts specifications about?
Bolts and nuts are designed to work so that they strengthen whatever they are holding together. B.A. (British Association) screws bolts and nuts are used worldwide and have been one of the most useful products that played a major role in industrial applications.
BS 57 discusses standards for B.A. screws bolts and nuts. BS 57 specifies requirements and dimensions for both ferrous and non-ferrous screws, bolts and nuts. Screws and bolts may be either turned from bars or forged.
Who is BS 57 - B.A. screws bolts and nuts specifications for?
BS 57 on B.A. screws bolts and nuts specifications is useful for:
- Manufacturers and suppliers of screws bolts and nuts
- Organizations that design, build, and maintain screws bolts and nuts
- Industries where screws bolts and nuts are used (automobiles, aircraft, shipping, railways, appliances, agriculture industry, etc.)

Why should you use BS 57 - B.A. screws bolts and nuts specifications?
BA screws bolts and nuts are extensively used in Model Engineering where the smaller hex head sizes make scale fastenings easier to represent. BA sizes were also used extensively in aircraft and BA sizing is still used in railway signalling, mainly for the termination of electrical equipment and cabling.
BS 57 provides you with general dimensions for all the common types and sizes of B.A. screws bolts and nuts including cheese head screws, round head screws, countersunk head screws, raised-countersunk (instrument) head screws, hexagonal headed screws and bolts, and hexagonal ordinary (or full) nuts and thin (or lock) nuts.
BS 57 includes standard lengths for all the common types and sizes of steel and brass B.A. bolts and screws for wartime production. Following specifications provided in BS 57, lets you manufacture and supply high-quality B.A. screws bolts and nuts with long working life and no manufacturing defects.
