ISO 4014 Hex Bolt can be surface treated to variations of coatings. For instance, it can be coated with zinc by either electroplating or by immersing the fastener in zinc during hot dip galvanization. Other surface treating techniques include the finishes like auto black, dacromet, geomet and phosphate. Plating the alloy can also be utilized to increase the ISO 4014 bolt weight. DIN 931 ISO 4014 bolt are externally threaded fasteners with a hexagonal washer faced head and a chamfered tip to facilitate mating with an internally threaded component.
