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 bolts or in special rock conditions. Consult your Williams Representative for more specific details.
(3) Stress to desired tensile load using a hollow ram hydraulic jack. Consult your Williams Representative.
(4) WILLIAMS reserves the right to ship full length or coupled units as necessary.
(5) ACI 355.1R section 3.2.5.1 indicates an ultimate strength in shear has a range of .6 to .7 of the ultimate tensile strength. Designers should provide adequate safety factors for safe shear strengths based on the condition of use.
(6) 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.
(7) All above torque values are used for clean, dry (un-greased) threads. For greased thread torque values, contact your local Williams representative.
