The Hobson acronym list defines BSW as British Thread Standard Whitworth and TPI as threads per inch (manufacturer-stated). The threads per inch shown are from the Hobson thread table, for the sizes it lists.

The Hobson spanner chart has no column for BSW, so no spanner size is published for these items.

The Hobson acronym list describes ZP as zinc, usually referencing zinc plating (zinc with clear chromate) (manufacturer-stated). The supplier description for these items says Zinc Plated and gives no passivate detail.

Key specifications

Selecting the right option

Choose the thread form first: the nut must match the bolt in thread form, diameter and pitch. Sizes are nominal diameters in inches; compare the threads per inch in the table with your nut. Length is measured from under the head to the end of the bolt. For a bolt and nut set: see Hobson BSW Hex Bolt and Nut, Zinc Plated, 1/4" to 3/4" x 1-1/4" to 7".
