Crocess Recessed/ Phillips Flat Head Concrete Screw with Sharp Point
Raw Material: Carbon Steel
Carbon steel is a steel with carbon content up to 2.1% by weight.
As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. In carbon steels, the higher carbon content lowers the melting point.
The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.
Case hardening processes harden only the exterior of the steel part, creating a hard, wear resistant skin (the "case") but preserving a tough and ductile interior.

Concrete Screws Introduction
Concrete screws, also known as masonry screws, are a type of fastener that holds one or more objects together or secures an object in place. They are commonly used to fasten certain materials, such as metal or wood, to concrete or masonry. Concrete screws are commonly made of steel, galvanized steel, or carbon steel, and they can have a finish such as zinc or blue stalgard. Often blue in color, they are sometimes referred to as blue screws. Manufactured in a variety of sizes, lengths, and threads, they can have right-hand or left-hand threads, a combination, or step-thread design. They can have various head or drive styles, such as a flat, hex, or hex washer head, and a Phillips or slotted drive. Concrete screws can be manufactured to meet specifications.
The concrete screw is made from Carbon Steel, and is Black. This concrete screw is designed for use in Concrete, Block, and Brick.
The concrete screw is designed for use in a Dry environment.
The concrete screw is a Flat Countersunk Phillips head and is designed to prevent the head from protruding above the surface of the item being attached.
Hole Diameter/Bit Diameter
The concrete screw requires a 5/32" 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.
