Quik Drive: General Load Tables

Screws have been tested per AISI Standard Test Method TS-04 using a 0.175" thick steel plate. The tabulated allowable loads are based on the screw strength itself with a factor of safety determined per 2001 AISI NASPEC & 2004 NASPEC Supplement section E4.
The tabulated values may be increased by 1/3 for seismic or wind loading as allowed in 1997 uniform building code and 2000 IBC if alternate load combinations are used.

Values based on lesser of Quik Drive screw strength (see table 1, above) or strength of the screw in the connected members.
Screws and screw connections have been tested per AISI Standard Test Method TS-05. The tabulated allowable loads are based on the lower of the screw strength itself or the strength of the screw in the connected members per 2001 AISI NASPEC & 2004 NASPEC Supplement section E4.
Values are based on cold-formed steel (CFS) members with a minimum yield strength of Fy=33 ksi and tensile strength of Fu=45 ksi for 43 mil (18 ga) and thinner and a minimum yield strength of Fy=50 ksi and Fu=65 ksi for 54 mils (16 ga) and thicker.
Minimum thickness represents 95% of the design thickness and is the minimum acceptable base metal thickness based on 2001 AISI NASPEC section A2.4. Design thickness for the steel sheets are: 33 mil=0.0346", 43 mil=0.0451", 54 mil=0.0566", 68 mil=0.0713", and 97 mil=0.1017".
Screw diameters per 2001 AISI NASPEC Commentary Table C-E4-1.
Minimum required screw length is the lesser of 3/4" or the minimum length required for the screw to extend through the steel connection a minimum of (3) exposed threads per AISI General Provisions Standard section D1.3. 7. Larger of screw head or washer diameter, dw, for #10 and #12 screws is 0.375".
The tabulated values may be increased by 1/3 for seismic or wind loading as allowed in 1997 uniform building code and 2000 IBC if alternate load combinations are used.
