Whitworth box,combination,open ended spanners,sockets.

Whitworth/B.S.F and B.A spanners,sockets,box spanners,taps,dies . A conversion chart for Whitworth to BSF to imperial or metric wrench sizes is at the foot of this page.. For restoring and repairing machines made before metric fittings became common you need imperial,whitworth or BSF tools.Imperial measurements might be obsolete but there are thousands of bikes from AJS and BSA to Triumph and Velocettes and cars from Austin sevens to Wolseley and relatively modern Land Rovers that use them. Metric spanners and sockets aren't made to fit the UNF,UNC,whitworth and BSF or BA nuts and bolts found on most classic vehicles or motorcycles.Whitworth and BSF fixings are not interchangeable with SAE or metric fastenings.I can supply good quality Whitworth/BSF ring,open end and box spanners, sockets and other tools for your older motorbike,car or aeroplane.Some from long established English tool makers,who might have supplied the original tool kit your vehicle started life with.There is no need to damage the imperial fastenings on your restored British classic when I still have the correct spanners on sale Whitworth taps and dies are available as well as BSF and BA. All prices on this site are inclusive.Some items have google checkout buttons,these are for UK delivery only.
Overseas orders welcome, ordering details,guarantees ,terms and conditions here. Below is a small selection of the whitworth,BSF and BA tools I have on sale at any one time,I also sell tools on Ecrater in the US.and Ebid in the U.K. I've sold a big range of imperial and metric tools at E-Bay auctions for years (often attracting higher prices than here) I've been involved in repairing and restoring cars,bikes and boats for over fourty years,I don't sell tools I wouldn't use myself.

Please note....some of the British made Imperial spanner sets may have VERY slight variations in the appearance of the odd socket or spanner,this is normally due to different years of manufacture.All will be of identical good quality,unused and from the same maker.I do NOT substitute cheap Indian or Chinese spanners to make up sets in imperial sizes as many of these are poorly made from inferior materials,if cost is your only consideration you can buy cheap imported sets from lots of places..
It would be virtually impossible to list all the imperial tools in stock,only a selection is listed on this site.In addition to secondhand spanners of all types and sizes,I have large stocks of old,but never used,sets and single whitworth/BSF open ended and ring or combination spanners of German and English manufacture King Dick,Britool,Bedford,Gedore,Snail Brand,Williams and ELORA etc some dating back to the 1940's.I stock six sided impact sockets,even deep ones in whitworth and af sizes.I can often replace missing sockets or spanners to complete a set.Older motorbikes and cars often had imperial tool kits supplied by makers that are no longer trading,Vincent for example used a lot of 'Jenbro' spanners made by Jennings brothers who ceased trading some years ago.Whilst I cannot always supply identical spanners I can usually match the sizes of missing tools.I guarantee everything that I sell fit for purpose.Some whitworth impact sockets are difficult to source at an economic price but using very cheap tools is a false economy.In cases of non availability of the correct whitworth/BSF sockets most engineers accept that 18mm is comparable to 3/8 whit (actually 18.03mm),33 mm is an acceptable replacement for 3/4 whit (33.02mm) and 52mm for 1 1/4 inch whitworth.
I can also supply model specific wheel braces in imperial sizes.Forget worrying about breaking your 1/2 drive bar undoing tight wheel studs,some of these braces are made in England from two inch diameter solid steel bar!.
I sell whitworth and BSF tools suitable for all older machinery,from Armstrong Siddeley to Gipsy Moth,from a AJS to a Velocette I can supply spanners to suit.

Taps and Dies.

Those working on older machinery are likely to come across various thread forms.The modern metric plus unf,unc,ba,whitworth,BSF,cycle thread,gas and others.I can supply most of these,please ask.

Whitworth/BSF/Imperial/Metric conversion tables. The markings on a spanner or wrench for whitworth or bsf indicate the thread size,for af they indicate the width of the nut/bolt head.A.F stands for "across flats" not American fine.

A tubular box spanner or six sided (six point) socket the closest size upwards might be a solution in an emergency (ie) a 19mm spanner will probably fit a 3/4 inch af nut.These have greater tolerance than 12 sided sockets but there is always a risk of damage to socket and or the fastening.Impact sockets are almost always six sided (mono-hex).Six sided sockets are less liable to mark or damage brass,alloy or chromed fixings such as wheel or hub nuts.

Footnotes...It's recorded at least one English motor manufacturer in the 30's-40's using imported engines with metric threads,ground the heads of nuts and bolts down so that mechanics whitworth spanners would fit.Some smaller or more specialised makers used whitworth fastenings for some years after everybody else had decided they were obsolete and went over to UNF/UNC or metric,so even without any previous owners swapping and repairing bits it's not unusual to find an assortment of fastenings on old (and not so old) cars. Land Rovers for example have a transmission design with parts of it dating to the 1930's so it should be no suprise to find sundry whitworth fastenings scattered round the gearboxes on early models and I'm told BA fittings are still found on modern JCBs. This is why joining an owners club and talking to other classic car and motorbike enthusiasts makes sense. I've seen on at least two web sites that some whitworth and SAE (UNF/UNC) or metric nuts and bolts are interchangeable.This is wrong and could be dangerous if applied to critical components (suspension/brakes etc) The thread rate (threads per inch) might be the same in some cases but the thread angles are different (55 degrees for whitworth and 60 for metric,UNF and UNC) resulting in loss of strength leading to thread stripping or fastenings coming undone in service.The use of a decent thread guage to identify threads on classic car and bike restoration is advised.
