1 Screw-Anchors Screw-Anchor are a totally removable rotation setting, thread forming anchor, ideal for either temporary or permanent anchoring into substrates such as concrete, brick, hollow brick or block. The Screw-Anchor is particularly well suited to close-to-edge or close-to-anchor fi xing as it does not expand and burst the surrounding substrate. FEATURES Quick installation with a drill and drive method using a hex socket, ratchet spanner or a torque controlled impact wrench. Chamfered tip for easy centering. Unlike chemical anchoring or sleeved anchors, Screw-Anchors can be removed with ease leaving the hole clear of debris. An increases in durability and reliability on installation of the Screw-Anchors, is a result of the dual-hardened body. The large self-tapping thread feature of this anchor is designed for fast advancing and high performance capacity as threads are formed in substrate material on installation.

4 Screw-Anchors MATERIAL SPECIFICATION Screw-Anchor are manufactured from a dual hardened heat treated carbon steel that is plated to a commercial standard coatings in both electroplated zinc (clear) and mechanically galvanised finish. Anchor Body Plating Zinc Clear Plating Mechanical Galvanised 10B21 Boron Steel 5 microns (min.) AS1789-FE/ZN 25 microns (min.) AS Bi-Metal Screw-Anchor material specification provides superior corrosion resistance and lifespan for use in outdoor environments over other material. The Bi-Metal anchor uses 316 (A4) marine grade stainless steel in the loading area combined with a case hardened carbon-steel tip for the purpose of commencing the threading action into concrete.

5 SETTING BASE MATERIAL THICKNESS (BMT) There is a recommended minimum thickness of the solid base material that the anchor can be set in. The minimum is based on 1.5 times of the calculated embedment to be used. Eg. an anchor to be installed to a depth of 100 mm, the base material should be 150 mm deep. Spacing - a pre-determined depth to obtain the required load capacity. Equal to or greater than the minimum embedment allowance. Drill Depth - is the required embedment depth into the substrate plus a cavity allowance approximately 1.5 times the anchor diameter. SPACING Anchor spacing should be determined by 10 times the selected anchor diameter (10d) to obtain the maximum load in tension or shear. This spacing can be reduced but the load value should also be reduced. The recommended minimum spacing is 5 times the selected anchor diameter (5d), which will have a load rating reduced to 50%. BMT Edge Distance Anchor SPACING LOAD CAPACITY 10 x d 9 x d 8 x d 7 x d 6 x d 5 x d Reduce by 100% 10% 20% 30% 40% 50% Reduction Factor EDGE DISTANCE Should be determined by 10 times the selected anchor diameter (10d) to obtain the maximum load in tension or shear. The recommended minimum spacing is 3 times the selected anchor diameter (3d). In tension reducing the edge distance to the minimum, the load value will reduce by 30%. Edge Distance in TENSION only LOAD CAPACITY 10 x d 9 x d 8 x d 7 x d 6 x d 5 x d 4 x d 3 x d Reduce by 100% 3% 8% 13% 17% 20% 24% 30% Reduction Factor In shear reducing the edge distance to the minimum, the load value will reduce by 85%.

Tightening - High Loads are achieved by the Screw-Anchor forming a thread in the substrate. There is no requirement to tighten the anchor to any specific torque. However, please take care not to over torque the Screw-Anchor, see table below. Fixture A. Anchor B. Clearance C. Flanged Height D. Washer E. Wrench MAX. Torque (Nm) Drill Depth Depth B A. INSTALLATION GUIDE Drill or core a hole to the recommended diameter and depth using the fixture as a template. Clean the hole thoroughly removing debris with a hand pump, compressed air, or vacuum. Place the Screw-Anchor through the fixture. Drive in the anchor using an appropriate socket & impact wrench* using slight pressure to start the self-tapping action. Tighten the Screw-Anchor until the fixture is held firm. If resistance is experienced when tightening, unscrew the anchor one turn and re-tighten. Ensure that you do not over tighten. *An impact wrench with a 260Nm capacity is recommended for hardened concrete. A socket wrench can be used by hand for porous material such as brick.
