How to Install Concrete FastenersConcrete fasteners are referred to as expansion type concrete fasteners. They derive their holding values from friction. The friction is obtained by the outward pressure tren marruecos espana by dyna bolts into wood djna anchor against the walls of the hole that is drilled in the base material. All expansion anchors work on this principle. The only one that does not is the concrete screw.
Concrete fasteners are referred to as expansion type concrete fasteners. They derive their holding values from friction. The friction is obtained by the outward pressure created by expanding the anchor against the walls of the hole that is drilled in the base material. All expansion anchors work on this principle. The only one that does not is the concrete screw. Each type of anchor has a minimum embedment- the minimum distance in inches that the anchor must be inserted into the base material for it to obtain its holding values.
The deeper the embedment into the base material, the better the holding values. Expansion anchors must be spaced a minimum of 10 anchor diameters away from each other and no closer than 5 anchor diameters from an unsupported edge.
To install a concrete anchor, a hole must be drilled in the base material. Carbide tipped drill bits that meet ANSI standards must be used as they are tolerance matched to the concrete fastener. This allows for any material to fall when the anchor is inserted into the hole.
After the hole is drilled, it must be cleaned of all debris, material or dust. All of this information should assist in the safe and correct installation and use of concrete anchors and fasteners no matter what your application may be. Zinc Plated Wedge Anchors. Hot Dipped Galvanized Wedge Anchors. Zinc Plated Sleeve Anchors. Stainless Steel Sleeve Anchors. As with any anchoring project, it is important to keep safety in mind and follow instructions carefully.
Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete fasteners. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project. Mike Pistorino , Vice-President Operations. Concrete Fastening Systems, Inc. We can ship out one box or a whole pallet of concrete anchors.
Our products are of the highest quality We ship all orders the same day the order is received. How to Install Concrete Fasteners. Steps to Installing Concrete Fasteners To install a concrete anchor, a hole must be drilled in the base material. Wedge Anchor - for use in concrete only Drill hole into the concrete using a carbide tipped bit that meets ANSI standards.
The hole can be drilled while the fixture is in place. It is important to make sure that the bit diameter being used will fit through the hole in the fixture. Clean out the hole using a wire brush, compressed air, vacuum, blow out bulb or another method.
Put the nut and washer onto the wedge anchor and make sure that the nut is on the last threads this will protect the threads from damage when the wedge anchor is hammered into the hole in the concrete. Insert the wedge anchor through the fixture's hole and into the hole in the base material. This should be a very tight fit- use a hammer to complete the installation until the nut and washer are tight against the fixture.
It is important that the threads go below the surface of either the base material or the fixture. Turn the nut clockwise, until finger tight. Using a wrench, turn the nut times until snug. The recommended torque values can be found here. Sleeve Anchors - for use in concrete, brick or block Using ANSI standard drill bits, carefully drill a hole in the base material.
Minimum embedments also need to be met. The hole can be drilled with the fixture in place making sure the bit will fit through the fixture hole. Clean the hole of all debris made during drilling. Sleeve anchors come fully assembled with a nut and washer. It is important that the nut is on the end of the threads to protect the threads during hammering. Insert the sleeve anchor through the fixture hole and into the hole you drilled in the base material.
A hammer will be required to pound the sleeve anchor into the material until the washer and nut are tight against the fixture. Tighten the nut until finger tight, always turning clockwise. Using a wrench, turn times until you are sure it is snug.
Drop-in Anchors - for use in concrete only The diameter of a drop-in anchor refers to the inside diameter. Carbide tipped drill bits meeting ANSI standards must be used. The hole can't be drilled while the fixture is in place due to the fact that the hole is larger than the diameter of the bolt being inserted into it. To use a drop in anchor- set the fixture in place, mark where the holes should be drilled, remove the fixture and then drill the holes.
Clean the hole of any debris before continuing. Insert the anchor into the hole. A setting tool is required to set the anchor. Setting tools will correspond to the inside diameter of the drop in anchor. Setting tool is placed inside the threaded portion of the anchor and struck until the lip of the setting tool touches the lip of the drop in anchor. This will ensure that the anchor is fully set in the concrete. Place the fixture over the drop in anchor and thread the bolt through the fixture and into the drop in anchor.
The properly sized carbide drill bit must meet ANSI standards. Clean the hole of all debris before continuing installation. Strike anchor needs to be inserted through the fixture and into the hole with the nut, washer, and set-pin in place until the nut and washer are tight against the fixture.
There is no need to use torque to set the anchor since it is set with the correct set pin. Lag Shields - for use in concrete, brick or block Lag shields are female type anchors.
Hole size must be larger than the inside diameter. Properly sized ANSI carbide bits must be used to drill the holes for lag shield anchors. Clean holes of any debris.
Place the lag shield in the hole with the closed end of the lag shield inserted first. The fixture is then placed over the lag shield, inserting a lag screw through the fixture and into the lag screw. Use a wrench to turn the lag screw clockwise until tight.
