Three cornered Philips type screwdriver

Who supplies this longer security bit sets? I have a regular occasional job that would be much easier with a longer set instead of the "creative" way I extend my short ones.

Am I alone in thinking these so-called security screws are an attempt by manufacturers to stop you mending things? When my electric fan fire got so full of dog hair that it was fire risk I had to resort to drill off the screw heads to get inside and clean it out. Replaced the screws with ordinary heads when I put it back together.

I'm with you on that Duncan, my take is that it stops you repairing it so you (in theory) have to buy a new one. What I don't get, is that on at least 2 pieces of equipment that I've seen there are only a couple of the "security" type screws and the rest are normal pozidriv / phillips. Why use 2 different types needing different tooling to make them as well, might as well use all security type. In the million off quantities that they equipment manufacturers buy them in there can't be any significant difference in price.

Having recently seen the inside of a fan heater that had these security screws, my other thought is that it stops you taking things apart so that you can't see just how shoddily the equipment is made! You're left having to guess from the shiny outside if there is any quality inside.

Not really on subject, -does anyone know how to get the tamper proof screws out that were used on railway carriages ? These had a "ramp cam " head that could only be turned to tighten. Last lot I did had to drill out. This is just for interest, don't expect to be doing it again soon.

Gordon,

My Dad worked at GKN, where those were generally known a 'Jail Door Screws'

To the best of my knowledge they can only be removed by drilling them out; or shearing the head off; or welding an extension to it; or [of course] if you want the screw, removing the wood from around it.

I bought a set similar to this one. It has "red/orange" handle with black stripes that is a bit heftier than this one but with a chuck on the end. The listing mentioned chrome vanadium. It contains 3 triangular tips.

It was a bit more expensive.

The Bergen set that KWIL linked to looks pretty comprehensive. Wonder what the real price is. Bit of Googling finds it from £8 ish up to £30 ish. What shook me was that the lowest price was from an outfit called DropShip which apparently lets folk set-up their own internet shop with zero stock and ships stuff direct to the final purchaser without the "shopkeeper" ever having laid eyes on what he or she is selling. Am I the only guy who thinks selling stuff you have never seen as an order taker for some other outfit is a tadge unethical. I guess expecting product knowledge or retailer quality control is so uncool these days.

Further Googling turns up so many varieties with different numbers of bits, different lengths and different tips that it will need a spreadsheet to sort out best buy. All imports from Far East Low End Supplier Inc so quality is likely to be a bit of a crapshoot. No doubt Snap On do similar but its the wrong time of the year to have my wallet mugged.

When did these long ones get common anyway. None to be found when I looked a couple or four years back.

I always though these were Clutch screws:

Vic,

Your link shows several different head designs ... including the one that I linked.

Think I got my set from one of the bargain tool traders at an ME show
