Trev's Vintage Machine Shop

This is a set of 1/4 BSW (British Standard Whitworth) square nuts with machine cut threads, made from zinc plated steel. Each nut is 5/32 inch thick, and they fit a 3/16 Whitworth spanner size.

They are sold in packs of 4, 8, 12, 16 or 20 nuts. These vintage nuts are new old stock with varying amounts of surface rust from storage, but they are still perfectly usable. The photo shows a set of four nuts to illustrate their condition: some nuts have lots of surface rust. All items are dispatched quickly via Royal Mail 2nd Class, with tracked postage available at extra cost.

Not what you want? Return the item unused for a refund.

Free postage to UK mainland only. If you have any questions then please ask.
