    Default Where to buy BSW (Whitworth) thread fasteners in US?

    Hello all,

    I need a handful of 1/2"-13 BSW nuts and a few bolts.
    Is there any shop in the US where I can simply order some fasteners at reasonable cost?

    Thanks

    Yaz.. but if this happens more than once in a great while? You will have better choices of materials (seagoing & corrosion-resistant choices?) ... if you have a set of taps & dies:

    BSW tap & Die Set

    Or you can single-point them on your Hendey. The inch-based pitches are already there.

    All you need is a slightly different tool shape. And rounded tops..

    Blighty exported in Whitworth. All over the planet. So you'll find these in Asia and India as well. Cromwells & other UK suppliers list far nicer taps & dies. But cheap they are not.

    Seldom as I need oddballs, I've gone fifty years with Taiwanese & OLD Japanese-made HCS sets, used with great care.

    Plus "thread restorer" files, of course. Those are WELL worth having a really complete set of!

    I/2" 13 is UNC. If you can't get Whit I could send you some.

    Check your pitch.

    Check your thread flank angles.

    Check the fit against dirt-common 1/2-13 US

    Just because you see nicely rounded tops doesn't mean it is Whitworth.

    Just because it is an oddball pitch (if even it is..) doesn't mean the thread form is NOT Whitworth, either.

    Whomever came before you might have had access to a ... perish the very thought.. screwcutting lathe?

    Be grateful he didn't have MY sense of deviltry.. to fab a bleedin' Royal Navy Dreadnought-gun-turret self-tightening "one way" DARDELET thread ...for a BMW window crank arm tip!

    For no better reason that because I could.

    I still remember one of my first experiences with buying a new Taiwan-made machine about forty years ago. The nuts and bolts had 1/4-20 and 1/2-12 threads and a metric hex. I replaced them with UNC fasteners. I suppose those Taiwan fasteners had BSW threads, but I did not bother trying to find out.

    Authentic BSW hex dimensions are not sizes that US or metric wrench sets will fit, so get out the adjustable open-end.

    The tapped holes in the feet of Hardinge lathe beds from 1903 on for about thirty years were 1/2-12, but that was an old USA standard, not BSW.

    Taiwan.. and it s "industry".. had been under Japan's influence.

    Japan.. had bought HEAVILY . .from the UK ... Meiji restoration to just before War Two.

    Neighbour Army-Brat kid once had a well-crafted pre War-two Japanese push bike. Brought home by his Dad FROM Occupation Duty, immediate postwar Japan.
    Along with his Japanese Mum.



    All of it UK fasteners.

    Well...the push bike was,.. anyway...

    Meah.. usta bee.. US wrench makers had sockets and such in 32ds and even 64ths that DID fit ... a "frenemy" of a 1959 Triumph TR3 my motivator for acquiring a select few of such goods.

    The Jaguar & Range Rover are all-Metrifuckated now ....so no longer an issue.

    A couple of cautions about sourcing Whitworth. I've bought from sources both in US and UK and found that some screws and bolts seem to come from the same source, same undersized measurements and sloppy fit. So sloppy in fact that they fit in UNC nuts. 1/2-12 BSW is hit or miss on fit so in anything structural, I either turn my own screws ( unless the ones I have actually are a tight fit ) or re tap the hole to 9/16-12 UNC. That is a pretty orphan size too but available from McMaster or elsewhere. If you do much work on English machines you do need a set of wrenches and sockets as nothing fits our UNC stuff. Dave

    Maybe T-man has a local computer problem. I had no trouble navigating to the 1/2 BSW hex head cap screw page using Chrome.

    And the nut page. https://www.britishmetrics.com/Categ...st&paging=0-12
