3. Material
3.1 Bolts
All lag screws shall be made from one of the following materials:
a) Hot-headed lag screws shall be made from hot-rolled steel which has been produced by the open hearth. basic-oxygen. or electric-furnace process and which is of a grade and quality suitable to meet the requirements of this standard.
b) Cold-headed lag screws shall be made from steel cold-heading wire which has been produced by the open hearth, basic-oxygen. or electric-furnace process and which is of a grade and quality suitable to meet the requirements of this standard, and shall be reheated (stress relieved) if necessary to meet the requirements of this standard.
4. DimensIons
All dimensions are in inches prior to zinc coating.3
All lag screws shall be square or hex and in accordance with ANSI B I8.2.l-l996. as specified in Figure 3 and Figure 4.
Lug screw threads shall be machine-rolled or CLII as specified in the data sheets.
5. Strength
Lag-screw heads shall be of sufficient strength to develop the body tensile strength of the screws. Failure shall occur in the shank or threaded section and not at the junction of the head and shank. In no case shall the strength be less than the following.
