## Overview

The CONFAST 3/8" x 5" Flat Sleeve Anchor is a zinc-plated carbon steel fastener designed for dry environments. Compatible with concrete, brick, and block, it features a flat countersunk head for flush mounting and requires a 3/8" hole drilled with a carbide bit. Each box contains 50 anchors engineered for reliable embedment and maximum fixture thickness, delivering industrial-grade shear strength of 3082 lbs.

## Description

ApplicationsThe anchor is made from Carbon Steel, and is Zinc Plated. This anchor is designed for use in Concrete, Block, and Brick.EnvironmentThe anchor is designed for use in a Dry environment.Head Style The anchor is a Flat Countersunk head and is designed to prevent the head from protruding above the surface of the item being attached.Hole Diameter/Bit DiameterThe anchor requires a 3/8" hole to be drilled in the base material (Concrete, Block, and Brick). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill.Diameter of Anchor The diameter of the anchor is 3/8".Length Anchor The length of the anchor is 4"Minimum EmbedmentThe minimum anchor embedment into the concrete is 1-1/4". Therefore, the anchor must be installed so that a minimum of 1-1/4" of the anchor is embedded into the concrete.Maximum Fixture ThicknessThe maximum fixture thickness or the maximum thickness of the material being fastened for a anchor is 2-3/4". This will ensure that the minimum embedment of 1-1/4" will be met.Fixture Hole DiameterThe hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 3/8" diameter anchor requires the hole in the fixture to be 1/2".Spacing between AnchorsEach anchor must be spaced a minimum distance of 3-3/4" from each other when measured center to center.Edge DistanceIt is very important not to install the anchor any closer than 1-7/8" from an unsupported edge of the concrete.

Review: Perfect - Great anchors they did exactly what they were supposed to do
Review: Misleading description - IMPORTANT: The Phillips head screw is also a sleeve (inner threads). The anchor is a sleeve around a stud that will stick out of your concrete. Given the picture and the description, I thought that the sleeve left in the concrete would be flush and receive a Phillips head screw. But, they appear to be good/high quality. Even though I found a different solution at my local hardware store, I am keeping them for possible future projects rather than return.

### ⭐⭐⭐⭐⭐ Perfect
*by G***T on November 12, 2024*

Great anchors they did exactly what they were supposed to do

### ⭐⭐⭐⭐⭐ Misleading description
*by E***C on January 18, 2021*

IMPORTANT: The Phillips head screw is also a sleeve (inner threads). The anchor is a sleeve around a stud that will stick out of your concrete. Given the picture and the description, I thought that the sleeve left in the concrete would be flush and receive a Phillips head screw. But, they appear to be good/high quality.

### ⭐⭐⭐⭐ Work fairly good for Furring Strips
*by S***N on March 6, 2020*

I will have used approximately 500 of these to install 1 x 4 (pt) furring strips on my cement block home. They work pretty good. Where the blocks are solid (filled), I can use a 1/4" hammer drill bit, and sleeve anchors can be hammered in and tighten down perfectly. However, when the blocks are hollow (no cement filling), I have to use a 3/16" hammer drill bit very gently so as to not blow out the backwall of the block. This does make it harder to get the sleeve anchor in the wall, but if you use a larger bit, I found that they would simply turn inside the block and never flare out. It takes some trial and error, and every now and then, I had to install multiple anchors. Sometimes, I had to start flaring the anchor before fully sinking into the block, and gradually flare and work the anchor into the block cavity. This is not a problem of the sleeve anchor itself, although, I wish a smaller size was available. 2" is the smallest of this flat-head sleeve anchor that I have found anywhere. Overall great product for this application, but they require trial & error in cinderblock installation.
