The 3/16” x 1-1/2” flat head Drive® is a pre-expanded, tamperproof, one piece fastener made from zinc plated carbon steel for use in concrete and stone. Both the Powers Fasteners, Inc. brand and Concrete Fastening Systems, Inc. brand can be purchased on-line by going to www.confast.com.
Expansion Principle
The Drive® anchor is manufactured and heat treated larger than the designated diameter and, once placed in the correct diameter hole in the base material, it expands outward towards its original shape.
Applications
The 3/16” x 1-1/2” flat head Drive® anchors is used where tamperproof fasteners are required as well as in wood to concrete applications.
Listings
The Drive® anchors are UL listed (Underwriters Laboratory) VFXT.EX1289 and FM Global (Factory Mutual) J.I. Ok4A9.
Specifications of Material
The anchor body of the 3/16” x 1-1/2” flat head Drive® is made from AISI 1018 carbon steel that is heat treated and then zinc plated ASTM B633, SC1 Type III (Fe/Zn 5).
Length of Drive®
The length of the 3/16” x 1-1/2” flat head Drive® is measured as an overall length that includes the head. It is 1-1/2” long as designated by the second number in the description.
Diameter of Drive®
The first number, or 3/16” in the description, describes the diameter of the 3/16” x 1-1/2” flat head Drive®.
Head Size
The head of the 3/16” x 1-1/2” flat head Drive® measures 7/64” in height and 3/8” in width.
Hole Diameter
The diameter of hole that needs to be drilled into the base material is equal to the diameter, or 3/16”.
Bit Diameter
A 3/16” carbide tipped bit meeting ANSI standards B212.15 must be used to drill the hole in the base material. The bit must be used in a hammer drill set in the hammer and rotation mode.
Depth of Hole
The hole must be drilled to a depth that is 1/2” deeper than the 3/16” x 1-1/2” flat head Drive® anchor will penetrate the base material, allowing for the anchor to be embedded deeper than minimum embedment depth of 7/8”.
Minimum Embedment
The minimum embedment depth for the 3/16” x 1-1/2” flat head Drive® is 7/8”. This means that the anchor must penetrate the base material a minimum of 7/8” for the anchor to achieve its minimum holding values.
Hole in Fixture
The minimum diameter for a hole in a fixture for the 3/16” x 1-1/2” flat head Drive® is 1/4”. All Drive® anchors meet ANSI standards and the designated diameter of the anchor is smaller than the actual diameter. This means that when either the anchor is inserted through a hole in the fixture or the hole in the base material is drilled with the fixture in place, the hole in the fixture must be larger than the designated diameter of 3/16”.

Installation
Make sure that the 3/16” x 1-1/2” flat head Drive® is long enough to insure that minimum embedment depths will be met.
INSTALLATION VIDEO
- Using a hammer drill that is set in the hammer and rotation mode, drill a hole in the base material with a 3/16” carbide bit that meets ANSI standards B212.15. Drill the hole to a depth of 1/2” deeper than the required embedment.
- Blow the hole clean of all dust and debris created during the drilling process.
- Drive the anchor with a hammer through the hole in the fixture and into the hole in the base material until firmly seated against the surface of the fixture.
