Fiberglass studs and nuts for mechanical fastenings

First used in 1977, FIBREBOLT fiberglass studs and nuts are ideal for applications requiring mechanical fasteners that must be non-corrosive, low in conductivity, and/or transparent to electromagnetic waves. FIBREBOLT studs are machined from pultruded fiberglass vinyl ester rods. The hex shaped nut is thermoplastic. They are easily assembled with a standard six point socket wrench. FIBREBOLT studs and hex nuts are available in diameters of 3/8″, 1/2″, 5/8″, 3/4″, and 1″. Four-foot bolt length is standard, with custom lengths and partial length threading available on request. Brown is the standard color. The studs and nuts have UV inhibitors to provide resistance to ultraviolet degradation and corrosion.

Typical applications include:

  • Chemical process equipment

  • Air and water pollution equipment

  • Marine applications

  • Cellular antenna mounts and screens
