Fastener HSN Code: Classification for Metal and Industrial Fasteners
Fasteners are essential components in construction, automotive, machinery, and furniture industries. Common types include nuts, bolts, screws, washers and rivets. Under GST, metal fasteners must be mapped to correct HSN codes so that purchase and sale entries are consistent.
Traders of hardware, industrial supplies and engineering goods should understand fastener HSN codes clearly.

How Metal Fasteners Are Classified under HSN?
Metal fasteners are grouped based on:
- Their function of fastening or joining parts
- Their construction, such as threaded or non threaded
- Their base material, usually iron or steel
Examples:
- Hex bolts, foundation bolts, anchor bolts
- Hex nuts, lock nuts, dome nuts
- Plain washers, spring washers
All these are grouped together in the main fastener heading. The HSN distinguishes them from other small hardware items that are not fasteners.
The HSN Code for Industrial Fasteners
Industrial fasteners used in heavy machinery, bridges, or large structures may be of special grades, coatings, or high strength classes. However, their basic nature as bolts, nuts, or screws keeps them in the same fastener heading.
Only when a fastener becomes a very special part of a machine with unique design might the classification shift. For normal trade, standard fastener HSN is followed.
Types of Fasteners and Their HSN Code Classification
Common types of fasteners include:
- Bolts and nuts
- Screws and machine screws
- Washers and circlips
- Rivets and pins
These are all mapped to the same broad fastener heading if made of iron or steel. Fasteners made from plastic or aluminium may be classified under other material specific headings.
