Tappers are designed to be used in a wide variety of base materials, including the following:

  • Normal Weight Concrete
  • Structural Lightweight Concrete
  • Grouted Concrete Masonry Block
  • Hollow Masonry Block
  • Brick

Tapper Lengths
The standard blue Tapper comes in lengths ranging from 1-1/4” to 4” in the 3/16” diameter to 1-1/4” to 6” in the 1/4” diameter.  Both the hex and flat head are manufactured in the same lengths for both diameters.

Depth of Hole
The hole drilled for the Tapper must be a minimum of 1/4” deeper than the Tapper will penetrate the base material.  This extra space at the bottom of the hole provides an area for dust that is created during the tapping process of the base material to fall into.  It is important that the Tapper does not bottom out in the hole before the head is secure against the fixture being fastened.

Hole Diameter
The hole that is drilled into the base material is critical to the holding values obtained by the Tapper in any application.  The hole must be drilled using a hammer drill in the hammer mode, using carbide tipped bit that meets ANSI standards.  An ANSI standard bit will ensure matched tolerance between anchor diameter and hole diameter tolerance.  The 3/16” Tapper requires a hole drilled with a 5/32” bit, the 1/4” Tapper needs a hole drilled with a 3/16” bit and the 3/8” Tapper must have a hole drilled with a 5/16” bit.

Installation Torque
The Tapper+ is the new and improved version of the Tapper.  According to Powers Fasteners, the Tapper+ provides a torque reduction thread design that allows for less torque needed to install the screw.  The original Tapper required 190 inch-pounds of torque while the new Tapper+ requires 115 inch-pounds of torque, which represents a significant reduction.  It is important not to over torque the Tapper once installed to avoid stripping of the threads in the base material, which would cause the Tapper to just spin in the hole or shear off.

Tapper Installation

  1. With a hammer drill in the hammer mode, drill a hole in the base material using the correct diameter carbide tipped bit for the diameter of Tapper being installed.
  2. Drill the hole to a depth that is 1/4” deeper than the Tapper will penetrate the base material.
  3. Clean out the hole of all dust and debris.
  4. Using a wrench, screwdriver or drill (rotation mode only), turn the Tapper clockwise until the head of the Tapper is tight against the material being fastened.

Always use personal protective equipmentAs 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.
