Why Silicon Bronze?

Silicon bronze offers superior corrosion resistance in marine and outdoor environments, non-magnetic properties for sensitive electronic or magnetic applications, and attractive appearance for visible hardware. This makes these screws a versatile choice for projects where reliability, longevity, and aesthetics matter.

Applications

  • Marine hardware and boat fittings
  • Wood-to-metal or metal-to-metal assemblies in outdoor settings
  • Electrical and electronics housings where non-magnetic fasteners are desired
  • Decorative hardware on furniture, cabinetry, and architectural projects

Note: For best results, pair with matching silicon bronze nuts or washers and pre-drill pilot holes appropriate for the material you are joining. Suitable for moderate torque applications; not recommended for high-torque structural uses.
