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.
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.

Spherical Washers
These adjustable angle washers are self aligning and provide full hex nut bearing. They can be used with Domed Plates or with thicker standard plates with chamfered holes. Use a hardened flat washer between the nut and spherical washer.

Constant Torque Nuts
These hex nuts have a special compressed end to allow a predictable torque resistance while torquing the nut/bar on the outer end of a threaded anchor bar. This resistance allows the bar to be rotated by the constant torque nut to mix polyester resin or to initially set a mechanical bail anchor. After the resin sets or the bail anchor is set, the nut can then be torqued to a higher torque to tension the anchor to the required load for a one step installation. Some of the torque resistance will remain on the nut after the initial "break away" torque.
Constant Torque Nuts are available with UNC or All-Thread Rebar type threads. Allow 1/16" to 1/8" increase in the hex size of the drive socket tool for allowance of the compressed end of these nuts. Available for bar sizes listed above. See your Williams representative for the size and torque requirements for this product.

Spherical Seat Constant Torque Combination Square Nut/Washer
Williams has combined the spherical seat washer with a square nut to deliver a one piece fastener that will both spin the bar and then self align as it contacts the bearing plate. This nut features a constant torque compressed ring to allow a predictable torque resistance similar to the constant torque nuts above. Some of the torque resistance will remain on the nut after the initial "break away" torque of approximately 70 ft./lbs. The nut is available only with 1-1/8" square drive and for the following bar sizes: #6 Grade 75 All-Thread Rebar, 3/4"-10 and 7/8"-9 UNC, and 3/4"-4-1/2 Coil.
Break Away Dome Square Nut
This square nut has a thick washer bearing surface and a hollow dome that can be compressed to create the constant torque feature. Unlike the other constant torque nuts, there is no torque resistance after the initial "break away" torque. The nut is available only with 1-1/8" square drive and for the following bar sizes: #6 Grade 75 All-Thread Rebar, 3/4"-10 and 7/8"-9 UNC, and 3/4"-4-1/2 Coil.
Note: During installation using constant torque nuts of any type, ensure that the drill hammer is off or the steel shank in the drive steel has been shortened to eliminate any hammering in the drive steel.
