Determinations must be made on the diameter of the screw - standard or large diameter, length of the screw - ranging from 1-1/4" to 6", head style - hex slotted or flat Phillips, material or coating - Blue Climaseal®, Zinc Plated Large Diameter, Envirex Coated Large Diameter or Stainless Steel, embedment depth - 1” minimum to 1-3/4” maximum, and type of base material - concrete, brick or block. Once all of these factors have been determined, you can find the expected holding values in the technical information below.

To determine the minimum length required, add the thickness of the material to be fastened and the minimum embedment (1”). To determine the maximum length required, add the thickness of the material to be fastened and the maximum embedment (1-3/4”).

Anchor Spacing:

Allowable Edge and Spacing Distances - in NORMAL WEIGHT CONCRETE

Allowable Edge and Spacing Distances - in BLOCK
