R1J Solid Rebar 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) 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) Torque value listed will achieve approximate load of 50% of the anchor ultimate strength, and is based on the torque tension curves here.
(4) Stress to desired tensile load using a hollow ram hydraulic jack. Consult your Williams Representative. – Inconsistencies in rock from site to site and even from hole to hole may affect anchor performances. Fissures, voids, seams, rock psi, drilling through clay or bentonite and direction of bedding planes are all possible variables. Should problems occur, consult Williams for troubleshooting.
– Spin-Locks come standard with 12” of threaded area.  Other lengths available upon request.
– WILLIAMS reserves the right to ship full length or coupled units as necessary.

Head Assemblies

The Williams Spin-Lock anchor assembly gives full 300° 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 & Grade 80 All-Thread Rebar or 150 KSI All-Thread-Bar) is attached to the other end of the coupling.
