HOLDING STRENGTH
· 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.
SIZES
· 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".
· The length of screw measured from under the head
· Features a hex slotted washer head: 3/16” diameter needs a 5/32” hole and 1/4” diameter needs a 3/16” hole
· Special threads for efficient dust removal

INSTALLATION
· 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.
