Ideal Hex Nut M24 171527

This is an M24 hex nut supplied by Ideal as a spare fixing for its commercial heating appliances. It is a threaded fastener used to secure components and pipework connections within the appliance assembly, and it carries the manufacturer part number 171527. The nut is listed against the Ideal Commercial parts range, so it is intended for the larger commercial boiler and water heater platforms rather than the domestic wall-hung range.

• The nut has been removed during a repair and the original is lost, damaged or cross-threaded.
• Visible corrosion or pitting on the nut, common where it sits in a damp or condensate-affected area.
• Rounded or chewed flats from a previous attempt with the wrong spanner size.
• A joint that weeps or seeps at the nut face, indicating the fixing is no longer pulling down evenly.
• The nut has worked loose through vibration and will not hold torque on re-tightening.

• Confirm the part number 171527 against your appliance's parts list or serial number before ordering.
• Check the thread size on the fitting you are replacing — an M24 nut will not substitute for a different thread diameter.
• If the nut forms part of a water or gas-carrying joint, check whether a washer or sealing ring is also required for that connection.
