De Longhi Heater
I have a De Longhi fan heater type HVE320S which is faulty. It is held together by a type of security screw which seems to be a combination of hex and star form. Does anyone know where I can obtain a suitable driver and what the name of this type of screw is?
Many Thanks Bob |

Re: De Longhi Heater
Looks like a tamper proof version of a Torx screw. Keys to fit these will be found on eBay.

Re: De Longhi Heater
You can often get them out with an appropriately sized flat screwdriver. It depends how tightly they're screwed in.

Re: De Longhi Heater
You can buy sets of points for power tools that fit those from the local flea market.
Most kits also come with a manual handle. |

Re: De Longhi Heater
If you have 'ordinary' torx bits the middle pin snaps of quite easily.

Re: De Longhi Heater
I'd echo the above. Tamperproof torx. You can get the drivers but the centre pin can often be snapped off and a standard torx used.

Re: De Longhi Heater
Screwfix stock several sets of 'security bits' including the TX tamperproof Torx-profile. Catalogue number 2840V should cover what you need or one of the Screwfix own-brand 'Erbauer' kits catalogue number 12492 .
They all seem rather expensive for a one-off job, but more and more domestic appliances use this type of screw now so the cost has to be reckoned as an investment! I have found that a general shortcoming of all of the boxed-sets of bits is that often the fasteners are deeply recessed into the surrounding casing and that the bits are too short to reach the head. Fitting the bit-holder / extension doesn't help as its diameter is then too large to fit into the hole! Your photograph in post #1 suggests this might not be a problem in your case, but check before you buy! Hope this helps. |

Re: De Longhi Heater
When I needed torx bits last year it was cheaper in the local DIY/odds and ends shop to by security bits, and they naturally work fine for normal torx screws.

Re: De Longhi Heater
Hi Bob,
as others have suggested they can be found on ebay. Searching for: security bit sets finds a 10 piece set from around £1.50. However, I generally go as Paul suggests and remove them using a flat screwdriver or similar, and replace with a Screw that has a standard type head. I do have a set of Hex Security Bits, but often, like Jimbo, find the offending Screw too deeply recessed for them to reach. Regards - Mike |

Re: De Longhi Heater
Lidl supermarkets have a large box of these and other "secure" bits on sale

Re: De Longhi Heater
For stubborn screws (if that be shape or rounding off) I use a left hand drill bit, you usually have to replace the screw with a new one afterwards.

Re: De Longhi Heater
I had the same problem with a 'Tamper-proof screw' (the type which has a slotted head with a 'pip' in the center) in a Halfords Battery Charger. Unable to buy the correct type of screwdriver locally, and unable to use my interchangeable bit screwdriver (Diameter too large again!) I drilled off as much as I could of the'pip' then used a regular flat bladed driver to remove the screw.

Re: De Longhi Heater
I just cut a gap in the middle of an old flat blade screwdriver and have been using it for years to get those out and back in again.

Re: De Longhi Heater
They still work fine with ordinary slotted screws, too.

Re: De Longhi Heater
Out of interest, what is the problem with the fan heater?
I have a Stanley fan heater that after being stored in a shed now trips the RCD. The reason is that the elements, which are made of a heating coil embedded in ceramic inside a metal outer, have absorbed moisture into the ceramic and exhibit leakage from both L and N to Earth. The only cure is to replace the elements (not available) or run the heater flat out for a couple of hours with the earth connection off - while keeping hands off the metalwork! - to dry the elements out.

Re: De Longhi Heater
The other trick with those is to power it from 24 volts for a couple of hours.
The motor will not run however the element will run just hot enough to be uncomfortable to touch with your finger. It will not take more than a couple of amps. Just measure the cold resistance to be sure. |
