In section 8.5 of the current version, addressing screw length requirement, the first requirement (8.5.1) is too broad and does not address the distinctive length requirements of each screw type and purpose. The proposed revisions give purpose to the requirements and better align with 8.5.2, Type W and Type A screws shall be long enough to penetrate wood members not less than 5/8 in. (15.9 mm). The requirement for Type G screws follows references in the 2018 IBC to 1-1/2 in. Type G drywall screws. The requirement for Type S parallels AISI standards S240-15, C22.214.171.124 and S220-15, D1.2.
