NOTES:
(*) Do not exceed these numbers
(1) Care should be taken to drill a straight and properly sized hole.
(2) A function of strata strength. More torque may be required on long anchors or in special rock conditions. Consult your Williams Representative.
(3) Stress to desired tensile load using a hollow ram hydraulic jack. Consult your Williams Representative.
(4) ACI 355.1R section 3.2.5.1 indicates an ultimate strength in shear has a range of 0.6 to 0.7 of the ultimate tensile strength.Designers should provide adequate safety factors for safe shear strengths based on the condition of use.
(5) All above torque values are for greased (MolyKote GN) threads.
(6) WILLIAMS reserves the right to ship full length or coupled units as necessary.
(7) Inconsistencies in rock from site to site and even from hole to hole may affect anchor performances. Fissures, voids, seams, rock unfonfinedcompressive strength (UCS), drillingthrough clay or bentonite and direction of bedding planes are all possible variables. Should problems occur,consult Williams for troubleshooting.

Head Assemblies

The Williams Spin-Lock anchor assembly gives full 300 degree bearing area. The smooth shell design allows for maximum shell to rock contact and eliminates “point of contact” created by serrated designs. The cone design supports the shell 300°, thereby eliminating any possible collapse of the shell under high load conditions. The thrust ring stop in front of the shell prevents any possible rebound of the expanded shell down the cone when subjected to nearby blasting.The Williams Spin-Lock anchor has been field proven on the world’s largest projects to far exceed in tension capacity any other mechanical anchor on the market.

Coupled Head Assemblies

Williams can manufacture Spin-Lock Anchor systems with the use of a transition coupling, which allows the anchor to be designed with a continuously workable thread-form. This is advantageous when the anchor length may need to be adjusted in the field due to variable site conditions. The transition coupling engages a continuously threaded U.N. bar into the head assembly and the All-Thread Bar (typically Grade 75 All-Thread Rebar or 150 KSI All-Thread-Bar) is attached to the other end of the coupling.
