This standard covers the complete general and dimensional data for the various types of slotted and recessed head wood screws recognized as “American National Standard.” Also included are appendixes which provide specifications and instructions for penetration gaging and wobble gaging of recessed head screws; documentation for screw head types relegated to nonpreferred status; and formulas on which dimensional data are based. It shall be understood, however, that where questions arise concerning acceptance of product, the dimensions given in the tables shall govern over recalculation by formula.

(lFI Note: All Appendixes except Appendix IV have been omitted from this reprint. For all other Appendixes, refer to the complete standard.)
