IS 3975:2017 is the Indian Standard (BIS) for mild steel wire nails. IS 3975 covers common mild steel wire nails used in construction and carpentry. Specifies sizes from 20mm to 150mm, head types (flat, lost, panel pin), and finish (bright or galvanized). The most basic and widely used fastener in Indian construction.
Specification for mild steel wire nails (common nails) for general carpentry and construction use.

Practical Notes
! Use galvanized nails for exterior and damp locations — bright nails rust quickly.
! For formwork, 75mm (3") and 100mm (4") flat head nails are most common.
! Wire gauge determines shank diameter — lower gauge = thicker nail = higher holding power.
