Overview

ABB Installation Products Type SW Silicon Bronze Split Lock Washer (SKU 31030SW-C) is a corrosion-resistant fastener component designed for secure joint assembly in marine, electrical, and industrial applications. Constructed from silicon bronze, this split lock washer resists saltwater corrosion, galvanic action, and harsh chemical environments better than standard steel washers. The 5/16-inch diameter matches common bolt sizes, ensuring compatibility with standard hardware configurations. This Type SW split lock washer features a split design that increases spring tension when compressed, maintaining consistent clamp load on bolted joints under vibration or thermal cycling. The silicon bronze alloy provides electrical conductivity while preventing galvanic corrosion when paired with dissimilar metals like aluminum or stainless steel. Typical applications include marine hardware, electrical enclosures, outdoor lighting fixtures, and industrial equipment exposed to moisture or corrosive atmospheres.
  • Silicon bronze construction resists saltwater corrosion and galvanic action
