Trev's Vintage Machine Shop

This is a set of 5/16 British Standard Cycle (BSCy/CEI) imperial full hex nuts. These are good quality bar turned nuts with machine cut threads, made from stainless steel (grade 303). Each nut has a 5/16 inch diameter thread with a standard 26 TPI pitch. They measure 0.524 inches across the flats, and they are 0.250 inches deep (approx 6.36 mm).

They can be supplied as plain nuts, or nuts & washers. These are the same nuts that I supply with my 5/16 BSCy studs; they are ideal for anybody who has lost some nuts or needs a few spares. They are also perfect as general purpose fasteners, with many applications on motorcycles, scooters and cars etc.

They are sold in packs of 2, 4, 6, 8 or 10 nuts. All items are dispatched quickly via Royal Mail 2nd Class, with tracked postage available at extra cost.
