My son has just presented me with a fan heater, which had a stray piece of plastic carrier bag stuck in the fan. Every time he'd tried pulling it out, a bit had come off and the rest remained stuck inside. He asked if I could work out how to dismantle the heater.
The casing had four deeply recessed screws. Three were No. 1 Pozidrive, which came out easily. The fourth turned out to be a security screw needing a spanner bit like this one. The trouble was, the deep hole was too narrow to get a 1/4 inch hex security bit in, let alone the bulky adaptor needed to hold the bit.
A couple of minutes' work with a hacksaw and a file, the sacrifice of a long reach 6mm screwdriver, and I now have a home-made long-reach spanner bit driver, and the minor satisfaction of having overcome some manufacturer's desire to keep me out of the heater's internals.
No response needed: just thought I'd post it here in case somebody else faces a similar problem in the future.
