Brass Hexagon Half Nuts (DIN 439)

Brass Hexagon Half Nuts, often called Hex Thin Nuts or Flat Nuts, conform to DIN 439 standard or ISO 4035 and feature a reduced height. This is typically half the height of a standard hex nut to fit into spaces with low clearance or insufficient room for a full sized nut.
Designed for use with machine threaded screws and bolts, this component hosts a metric coarse thread and can be used as a Jam Nut – tightened against a full nut to create a locking mechanism and prevent self-loosening.
Compared to Fine Pitch Brass Thin Nuts, they are easier to fasten whilst providing greater durability in the form of increased resistance to cross-threading and galling.
Brass is widely used in decorative applications due to its attractive gold-like finish. It is rust-proof, water resistant and provides good levels of corrosion resistance – ideal for use indoors, outdoors and even underwater.
