R1J Spin-Lock Rock Bolt
The R1J uses an ASTM Grade 60 material for the anchor bolt which is generally less expensive than other Spin-Lock anchors which incorporate higher strength steels.

(*) Do not exceed these numbers
(1) Max factored design load is based on steel strength and shall not excede yield strength.***Note – ACI 318 limits the nominal strength of the anchor rod to 1.9*fy or 125 KSI, whichever is less***
(2) Care should be taken to drill a straight and properly sized hole.
(3) More torque may be required on long anchors or if the head assembly is next to rebar. Consult your Williams Representative for more specific details.
(4) All above torque values are for greased (MolyKote GN) threads.
(5) Stress to desired tensile load using a hollow ram hydraulic jack. Consult your Williams Representative.
(6) Full ultimate strength of anchor can be achieved at listed embedment depth, provided there are no edge or spacing effects on the anchor.
(7) WILLIAMS reserves the right to ship full length or coupled units as necessary.
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.

* Hollow-Core Spin-Lock only
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.
