Stainless Half Nuts – Grade A4

  • Called Half Nuts, Locknuts or Thin Nuts
  • Grade A4 – 316 Stainless Steel
  • DIN439

Used in conjunction with a full nut to lock the nut onto the bolt thread. The full nut is tightened first followed by the locknut. Using two spanners the full nut is reversed against the locknut to produce a locking action. Grade A4 stainless steel is used for fasteners requiring higher levels of corrosion resistance and is often referred to as marine grade or acid proof.
