BRITISH STANDARD WHITWORTH (BSW) TAPS
Offered at a VERY low price. These are old but unused IMPERIAL threaded HSS (High Speed Steel) Fluted Taps for cutting female screw treads. Suitable for hand or machine use.
Experts say....
"These [HSS] are more expensive than Carbon Steel but if your work is valuable that little extra is a good investment." All are UNUSED and at a price lower than you would normally pay for a Carbon Steel tap.
They are ALL at the same very low price. Mix and match with BIG multi-buy discount. Limited clearance. I have other sizes of BS taps on another listing identified below.
BRITISH STANDARD WHITWORTH TAPS
Cameras: "Historically, tripods used either 3/8 or 1/4 Whit (cameras were a British invention :-) although that has more recently been superseded by the UNC equivalents... which at least in the case of 1/4 have the same pitch albeit a slightly different form.
The important point is that there is a vast number of cheap tripods available, which makes that thread a de-facto standard if you want to e.g. rig up a small LED lantern for emergency use. Ditto for 3D-printing e.g. an adapter for a modern action camera which lacks a bush: it's possible to print surprisingly adequate threads (I've managed 0.75mm pitch for lens endcaps) but it's always better to clean up that sort of thing with a proper tool.
Pity that so many modern "makers" lack any sort of engineering background: many would benefit from it." I am grateful to e bayer: justmark08021 This comment has been reproduced with his consent.
