CONFAST® Hex Head Concrete Screw

More information:

• Works well in concrete, brick or block
• Blue coating helps resist rust
• Length of screw measured from under the head
• Hex slotted washer head
• 3/16” diameter needs a 5/32” hole
• 1/4” diameter needs a 3/16” hole
• Easy to install
• Special threads for efficient dust removal
• Can be taken out

• Designed to be used in applications where the head of the screw protrudes above the surface of the item being fastened.
• An example of an application for a CONFAST® hex concrete screw would be to fasten a light fixture to a brick wall.
• The CONFAST® hex concrete screw can be used in most masonry materials such as block, brick or solid concrete.
• Designed for indoor, dry applications.
• It has blue coating.

• A hole must be drilled in the base material before the CONFAST® hex concrete screw is driven into the base material.
• When driving the CONFAST® hex concrete screw, the threads of the screw taps threads into the base material. Always drill the hole slightly deeper than the screw will penetrate.
• Each diameter of CONFAST® hex concrete screw requires a specific diameter of hole, and the hole must be drilled using a hammer drill and a carbide bit.
• For minimum holding values, the screw’s minimum embedment in the base material is 1" and the maximum embedment is 1-3/4"
• A 1/4" hex nut driver is required for the 3/16", and a 5/16" hex nut driver is required for driving the 1/4" CONFAST® hex concrete screw.

• The CONFAST® hex concrete screw are considered a light duty fastener in both in the 3/16" diameter and 1/4" diameter.
• Holding values increase based on the depth of embedment, providing that minimum and maximum embedment requirements are met.
• The holding values differ based on the base material into which the CONFAST® hex concrete screw has been installed.

• To determine the size of The CONFAST® hex concrete screw required for a specific application, consider the size of the hole in the fixture, the thickness of the item being fastened and the weight of the item.
• The 1/4" diameter holds slightly more weight than the 3/16" 1 CONFAST® hex concrete screw.
• The minimum length of screw require for any job is determined by adding the thickness of the material to the minimum embedment depth of 1".
• The maximum length CONFAST® hex concrete screw is equal to the thickness of the material being fastened plus the maximum embedment depth of 1-1/4".
