Thin Hex Nuts are used primarily for the clamped counter-face of a bolted joint. This page summarizes where they fit, the industries that rely on them, and the practical points to get right when you specify them — to ISO 4035. Stocked across roughly M1.6 to M36, they cover general to heavy-duty work.
Typical Applications for Thin Hex Nuts
The most common settings where these are specified:
- Vibration-prone equipment: where a locking or flanged style resists loosening.
- Frames & weldments: captive or welded options for repeatable assembly.
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
How to Specify Thin Hex Nuts for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M1.6–M36; check the full table below for the exact dimensions of each size.
- Locking & grade: Match the strength grade to the bolt, and choose a locking style (nyloc, all-metal, serrated flange) if the joint sees vibration.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to ISO 4035. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Thin Hex Nuts Are Not the Right Choice
Not on their own — they need a matching bolt or stud — and a plain nut is not a substitute for a locking type under heavy vibration.
