The nut bolt hsn code is 7318, which covers screws, bolts, nuts, washers, rivets and cotter pins made of iron or steel, and the whole heading is taxed at 18%. Stainless steel fasteners are in the same heading, since stainless is a steel.
Nails sit next door under 7317, brass fasteners under 7415, and door tower bolts under 8302 as fittings. This page gives the 8 digit codes for each fastener, a hardware store invoice line and the codes people confuse. For sheets, bars and other steel forms, go to the steel hub.

Nut bolt hsn code on an invoice
From a hardware store bill: MS hex bolts M12 x 50 with nuts, HSN 7318 15, 500 pieces, taxable value Rs 9,500. CGST 9% Rs 855. SGST 9% Rs 855. Total Rs 11,210.
Fastener traders often sell hundreds of sizes. You do not need a separate HSN for each size; one line per type of fastener under its 6 digit code keeps the GSTR-1 HSN summary clean.
When fasteners go with a machine
Bolts supplied loose are 7318. Bolts sold fitted on a machine or as a kit with a machine are part of that machine and take its code. A spare parts kit for a specific machine may be classified with that machine's parts heading if it is specially made for it; standard bolts in that kit still count as 7318.

Special purpose fasteners can fall elsewhere, and the Council revises rates now and then, so look up the present entry on the GST portal and consult a GST practitioner or chartered accountant for unusual items.
