Ideal Hex Nut M12 Zinc Plated 000544

The Ideal 000544 is an M12 hex nut in mild steel with a zinc-plated finish, supplied as a spare fixing for Ideal Commercial appliances. It is used to secure components, bracketry and assemblies on the Concord Super series and other Ideal Commercial boiler ranges. As a standard threaded fastener, it holds a bolted joint firm where the manufacturer specifies an M12 fixing.

• The nut will not hold torque and works loose on the joint
• Visible corrosion, rust staining or breakdown of the zinc plating on the nut or its thread
• Rounded or chewed hex flats from a previous removal
• Stripped or cross-threaded internal thread that will not run down cleanly
• The original fixing is lost or dropped during a service or strip-down

• Confirm the appliance model and serial number against the compatibility list before ordering.
• Check the thread size on the existing fixing, as M12 nuts are used in more than one position across these ranges.
• Renew any washer or seal that sits under the nut if the joint is disturbed.
• Work to the torque figure given in the appliance service manual when refitting.
