Mechanical anchors are concrete anchors that move to create friction to obtain their holding values. Mechanical anchors vary in diameters from 1/4” to 1-1/4” and have different lengths up to 12”. Mechanical anchors include a variety of different types of anchors to meet most masonry fastening applications. Each anchor type has its own features and benefits allowing for different types of mechanical anchors to be used for the same application.
Power-Stud: a wedge type anchor designed for use in solid concrete only. It has the most consistent and best-holding values of any mechanical concrete anchor. It is available in zinc plated, hot-dipped galvanized and stainless steel. The Power-Stud SD1 and Power-Stud SD2 are designed and tested for use in cracked concrete.
Wedge-Bolt: a large diameter concrete screw for use in concrete with some diameters usable in block and brick base materials. The wedge bolt comes in diameters from 3/8’ to 3/4” and requires a special carbide tipped bit that must be purchased through Powers Fasteners.
Lok-Bolt AS: is a sleeve anchor made from all steel that is manufactured in diameters from 1/4” to 3/4”. It is sold fully assembled and ready to use. The Lok-Bolt AS is a versatile anchor that can be used in most masonry base material and is available in the standard zinc plated carbon steel or 304 stainless steel. Lok-bolts come in a number of different head styles: acorn head, hex nut head, flat head and round head.
Tapper: the Tapper is Powers Fasteners brand name for their concrete screw. The Tapper comes in two diameters of 3/16” and 1/4” and each diameter is available in two head styles of hex or flat. Different lengths are sold which range from 1-1/4” to 6” depending on the thickness of the material being fastened.
Steel Drop-in: a female anchor for use in solid concrete that is available in diameters of 1/4”, 3/8”, 1/2”, 5/8” and 3/4”. Drop-in anchors are manufactured in both a zinc plated carbon steel and a stainless steel. The steel drop-in requires a specific diameter setting tool to be used to set the drop-in anchor properly.
Mini Drop-in: a female anchor designed for use in post tension concrete or where shallow embedment depth is mandatory. The mini drop-in is a shorter version of the standard steel drop-in and comes in three diameters 1/4”, 3/8”, 1/2”. The mini drop-in anchor requires a setting tool designed exclusively for the mini drop-in because standard drop-in setting tools cannot be used.
Hollow-Set Drop-in: this drop-in anchor is designed for use in hollow base material such as masonry block, cinder block, and CMU. Five different diameters are available from 1/4” to 5/8”. A special setting tool is required to allow for flush mounting of the hollow-set drop-in anchor.
Double: is a double expansion anchor that expands along the entire length of the anchor body. The double is excellent for use in suspect base material and comes in six diameters from 1/4” to 3/4”. The designated diameter of the double is equal to the diameter of the bolt that goes into the anchor.
Single: the single is a single expansion anchor designed for use in concrete, brick or block base material. The single expands from only one end of the anchor and comes in diameters ranging from 1/4” to 3/4”.
Calk-in: anchor requires the use of a setting tool and is most commonly known as a machine screw anchor. Diameters include sizes from a # 8 to 1/2”. The calk-in anchor works in most masonry base material such as concrete, brick or block.
Lag Shield: Lag shields come in two lengths of a short version and a long version. Both lengths require a lag screw to be used to expand the lag shield anchor once it is installed in the base material. The short version is used in applications where the base material is very hard while the longer version is used in softer, more suspect base materials. Both the long and short version comes in diameters from 1/4” to 3/4” with the designated diameter referring to the diameter of the lag screw inserted.
Drive: the drive is the Powers Fasteners version of the split drive anchor that is manufactured in two diameters of 3/16” and 1/4” and in two head styles of a round head or a flat countersunk head. The drive is a one-piece pre-expanded mechanical anchor that is tamper-resistant and should only be used in solid base material such as concrete.
Spike: is a patented, one piece, pre-expanded mechanical anchor that is tamper- proof and can be used in vibratory loads and in concrete, brick or block base material. The Spike comes in 3 diameters of 3/16”, 1/4” and 3/8” and in different head styles, such as round head, flat countersunk and tie-wire.
Zamac Nail-In: the zamac nail-in has a body made from a rust resistant material called zamac with an expander nail that goes down the middle of the body. As the nail is pounded into the body, the body of the anchor expands against the base material. It is available in two diameters of 3/16” and 1/4” and in lengths up to 3”. The zamac nail-in comes fully assembled with either a zinc plated carbon steel nail or a stainless steel nail.
Adhesives and Foams: adhesives and foams are high strength adhesives for fastening to concrete as well as to hollow base materials such as brick or block. The adhesives come packaged as a two part in a cartridge or in glass capsules. The foams are expanding foams for filling voids in different types of construction applications.
Wall Anchors: anchors for fastening into different types of walls such as drywall, hollow block or brick. Each anchor has specific features and benefits for different types of applications, requirements and personal preferences.
