Ideal 003359 M4 Hex Nut Zp

The Ideal 003359 is an M4 hex nut with a zinc plated finish, listed by Caradon under code 3359. It is a threaded fastener used to secure components within Ideal Commercial appliance assemblies, where vibration and heat cycling make a correctly torqued nut essential. The zinc plating gives the nut a degree of corrosion resistance in the damp conditions often found around plant rooms and boiler housings.

• The nut has been removed during a strip-down and the threads show flattening, burring or cross-threading.
• Visible corrosion or white zinc oxide build-up on the nut faces, making it difficult to torque correctly.
• The nut spins freely on its stud or bolt without tightening, indicating worn internal threads.
• A fixing that has worked loose through vibration, leaving the associated component able to move.
• The nut is missing altogether after a previous repair, leaving a bracket or panel unsecured.

• Confirm the appliance model and serial number against the compatibility list before ordering, as fixings vary between assemblies.
• Check the existing nut or the parts list to confirm an M4 thread is the correct size for the position being repaired.
• Have the alternative number 1170096 to hand if you are cross-referencing against an older Caradon parts listing.
