    Grabber self-drilling screws have an ICBO Report (ER 5280)  See Table 4 for
    shear wall values.  There are also several ICBO's for diaphragm values with
    screws (ER-5053 & ER-5332).  Ensure you review the ICBO for predrilling
    requirements, the NDS requires predrilling lead holes for all wood screws in
    most wood species.

    Hope that helps.

    Subject:  Screws for Use in PLywood Shearwalls




    We are presently designing a plywood shearwall system which would utilize 2
1/2"
    10d nails  into a 2" x 4" stud. The owner has requested that screws be
utilized
    in lieu of nails.

    I do not have any charts giving comparisons of screws for use in shearwalls.
We
    have charts from NER-72 which compare staples and nails but there is no
values
    for screws.

    Does anyone know where I could look for this information on screws?
