Stone installation must be designed in accordance with acceptable engineering practices and the recommendations of the stone fabricator. Stainless Steel is recommended for stone anchors but also available in Hotdip Galvanized.
Strap Anchors: Typical dimensions are 1” (25.4mm) to 2” (51 mm) wide x 16 gage to 3/8” (9.5 mm) thick x length required.
Corrugated Anchors: Maximum steel thickness is 3/16” (4.76 mm), 1/8” (3.17 mm) for stainless steel.
Holes: Specify center spacing from designated end. Holes are typically 1/16” (1.58 mm) larger than the diameter of the dowel or fastener used.
Twists: Twist is 1-3/4” (44.45 mm) long. Specify the length from the end of the anchor to the start of the twist. Twist is not available on steel larger than 1/4” (6.35 mm) x 1” (25.4 mm), 3/16” (4.76 mm) x 1-1/2” (38 mm) or Stainless Steel larger than 3/16” (4.76 mm) x 1” (25.4 mm) or 1/8” (3.17 mm) x 1-1/2” (38 mm).
Split-Bends: Recommend minimum of 1-1/4” (32 mm) width and minimum 1/2” (12.7 mm) i.d. split-bend length.
Anchor Rods and Anchor Bolts: Continuous or partially threaded rods are available with UNC (course) threads from 6-32 to 2” (51 mm) diameter, and in lengths up to 144” (3.66 m). Stone Anchor Engineering Services are available in certain states through Heckmann for a fee.
