1-1/4''-7 Grade 8 Hex Bolt tape Installing a concrete screw too

Installing a concrete screw too deep will wear the threads and compromise the fasteners performance

31M Yield Strength and Tensile Strength Requirements Above Length is Measured from Under the Head to the Bottom of the Bolt

that is why they have a tight thread pattern

1-1/4''-7 Grade 8 Hex Bolt tape Installing a concrete screw tooGrade 8 hex bolts are made from medium carbon alloy steel and heat treated. A Grade 8 hex bolt has a greater tensile strength than a Grade 5 and Grade 2 hex bolt. They are designed for use in high stress applications. The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads.
