A Zamac material is used in the manufacture of the 1/4" x 1" hammer drive anchor body with pre-attached zinc plated carbon steel nail. Zamac is a non-ferrous metal that is rust resistant and is used in die-casting the anchor body.
Diameter – the first number, or 1/4”, refers to the diameter of the 1/4" x 1" hammer drive anchor.
Length – the second number, or 1”, refers to the length of the 1/4" x 1" hammer drive anchor. The length of the 1/4" x 1" hammer drive anchor is measured from underneath the head.
Designed for light duty fastening of any material up to 1/4” thick to concrete, brick or block and should not be used in any type of overhead application.
The head of the 1/4" x 1" hammer drive anchor is referred to as a mushroom head. It has a relatively low profile, with the width of the head about 1/2” across. It is tamper resistant. Once the head of the nail is fully seated into the head then the fixture cannot be removed without cutting the head of the 1/4" x 1" hammer drive anchor off.
The diameter of the hole that needs to be drilled into the base material for the 1/4" x 1" hammer drive anchor is 1/4”.
The bit to be used for drilling the hole in the base material must be carbide tipped, meet ANSI standards and be 1/4” in diameter. Meeting ANSI standards requirements will ensure that the tolerance between hole diameter and anchor diameter will be met.
The required bit must be used in a hammer drill when drilling into such base materials as concrete, brick or block. The hammer drill must be set in the hammer and rotation mode for the proper hole size and tolerance to be acquired.
The hole in the base material must be drilled a minimum of 1/4” deeper than the 1/4" x 1" hammer drive anchor will penetrate the base material. This allows space for any material that is created during the installation process to fall into and out of the way.
The hole in the fixture must be slightly larger than the diameter of the 1/4" x 1" hammer drive anchor and should measure a minimum of 5/16”.
The 1/4" x 1" hammer drive anchor must be installed into the base material a minimum of 3/4” for the anchor to achieve minimum holding values.
The 1/4" x 1" hammer drive anchor can fasten material up to 1/4” thick and still meet minimum embedment requirements.
Each 1/4" x 1" hammer drive anchor must be a minimum of 2-1/2” distance from each other and a minimum of 1.25” from an unsupported edge.
The 1/4" x 1" hammer drive anchor comes packaged pre-assembled in boxes of 100 pcs.
To order online use part number HD141
Use a 1/4” carbide tipped drill bit that meets ANSI standards and a hammer drill set in the hammer and rotation mode drill.
Drill hole to a depth of a minimum of 1/4” deeper than the 1/4" x 1" hammer drive anchor will penetrate the base material.
Using compressed air, vacuum and wire brush, clean all dust debris out of the hole.
Place hole in the fixture over the hole drilled in the base material and insert 1/4" x 1" hammer drive anchor.
Seat head of anchor tight against the surface of the material being fastened.
Using a hammer, strike the head of the nail with several sharp blows until the head of the nail is flush with the head of the anchor body.
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.
