Steel Bearing Plates

S1K - Round S1K - Keyhole R80 - Dished S1K - Studded S1K - Domed
Williams steel bearing plates are standard with a round hole for non-grouted anchors. Also available are dished plates for use with spherical hex nuts and keyhole plates which provide free access for grout tube entry. Bearing plates are customized for each application. Plate dimensions should be specified around the parameters of the project. In addition, corrosion protection should be considered along with specifying hole diameter and bar angle. Stainless steel plates available upon request.
End Caps

Williams offers end caps produced from fiber reinforced nylon, steel or PVC to provide corrosion protection at otherwise exposed anchor ends. Most often the caps are packed with corrosion inhibiting wax or grease. Caps made from reinforced nylon and steel are used in exposed impact areas. The fiber reinforced nylon end cap meets the Florida DOT standards.

Eye Nuts
Williams Eye Nuts may be used as lifting eyes for forms, concrete blocks, concrete cylinders, machinery or equipment. The large base on three of the models makes them excellent for anchoring guy wires. Safety factors and working loads based on the ultimate strength of the Eye Nuts should be determined for the specific application by the project design engineer.
