Would use them regularly in the forces, they would often be used on things to blend in better with paint or old metal, so you didn't have a brand new silver screw or bolt on display. Normally on display pieces rather than operational kit. operational kit was a case of get it working at any cost and cannibalise any other bit of kit if needed as the bean counters in whitehall would always find a way to leave you missing vital bits.
 
@Leesparkykent as has been mentioned, they were specified because of the head been round and unlikely to catch on cables, they were massed produced and cheap to boot, any roundhead screw would have done tbh if the question was asked.
It gets to be generically put in specs I bet if I looked thoroughly it will be in the spec I have now (spec still got supplementary bonding to suspended ceilings).
 
Black japan,was a finish,as mentioned,to prevent rust,and colour the fixing.

Round-heads,cheese heads,and a handful of other styles,were all commonly flush fitting,that is to say,not counter-sunk. This allows,moving any fitting,to level or align,before tightening.

A counter-sunk screw,always tending to centre the fitting hole,to the drilled one,whether aligned or not.
 
and in a lot of other stuff like plug tops. poxy screws that don't know whether they are slotted or pozi, and no screwdriver will fit. ( that's after you've scrounged all round the floor finding them as they drop out).
 
My personal pet hate is flat head screws in general. Bloody hate them.
You would not enjoy dismantling older shotguns,then:confused:
My friends grandfather,long gone,sadly,taught me some bench-hand carpentry,and all his work,was C/S slotted,where if brass screws were favoured,they were piloted on the "loose" or "held" side,and "cut" by running in steel screws of the same size,removing,then waxing the brass ones,and ensuring all the slots aligned with each other.

If i could have shown him a Hilti cordless,collated screw gun - he would have pooped :eek:
 
if you haven't had a star shaped palm injury off a yankee driver then your either too young and cannot appreciate what you have today or you are lying if you used one ,,, most painful tool in the box .

I gave mine away last year as I hadn't used it in 20 years, that one is missing the jubilee clip you stick on the shaft to stop it rolling of a scaffold tower when you put it down on the board.
 
I used them with orange MICC, just liked the look. (long time ago now)
Heathen, orange coated pyro and orange coated clips you used brass dome head slotted screws......... not black caps, sheeeeesh.
Well that's how I was taught by some great old boys,brass does sound good put a few quid on the price suppose.?
