Sleeve Nuts
Sleeve Nuts are ideal when tensioning or adjusting of the tie rods is required internally at the bar to bar connection. The sleeve nut is less susceptible to bending than the turnbuckle, however the turnbuckle allows the installer to see the thread engagement. Both components require right and left hand threads.

Clevis
A clevis can be used when tie rods are designed for angle adjustment, or when access to the outer side of the sheet pile is difficult. Designers must provide the hole diameter required in the structural steel to allow for proper sizing of the clevis pin. Pin diameters are available from 3/4” through 4-1/4” diameter.

Stop-Type Couplings
Williams mechanical couplers develop 100% of the All-Thread-Bar published ultimate strength. Couplers can be ordered Tap Thru or Stop-Type (ensuring 50:50 engagement). A coupler, as opposed to a turnbuckle or sleeve nut, is generally used when a splice is required and tensioning of the tie rod is easily accessible externally at the nut/plate interface.

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.

Articulating Coupler
Williams offers a specially designed articulating couplers for longer tie rod systems that allows the designer to mitigate soil backfill settlement concerns that potentially could cause failure of the tie rod in bending or shear. The articulating coupler allows freedom of vertical rotation on each side of the system as settlement occurs.
