Notes for Allowable Screw Design Values
N/A
Allowable screw connection capacities are based on Section E4 of the AISI S100-12 Specification.
When connecting materials of different steel thicknesses or tensile strengths, use the lowest values. Tabulated values assume two sheets of equal thickness are connected.
Screw shear and tension capacities were developed using published screw manufacturer data and evaluation reports available at the time of publication.
Screw capacities are based on Allowable Strength Design (ASD) and include a safety factor of 3.0.
When multiple fasteners are used, screws are assumed to have a center-to-center spacing of at least three times the nominal diameter (d).
Screws are assumed to have a center-of-screw to edge-of-steel dimension of at least 1-1/2 times the nominal diameter (d) of the screw.
Tension capacity is based on the lesser of pullout capacity in sheet closest to screw tip, or pullover capacity for sheet closest to screw head (using head diameter).
Screw capacities are governed by a conservative estimate of screw capacity, not by sheet steel failure.
For higher screw capacities, especially for screw strength, use specific screws from specific manufacturer. See manufacturer’s data for specific allowable values and
installation instructions.
Construction Advantages
N/A
High-strength steel combined with low-profile flange stiffening grooves and double offset web planking increases strength and provides greater limiting heights
Diamond-embossed web creates stiffness, reducing flange fade and screw spinout during drywall installation
Strong, lightweight stud and track cuts and handles easier than conventional flat steel studs
Flange grooves provide sight line for drywall alignment and aid in positioning screws at drywall joints to maintain the 3/8" edge requirement
Web and leg enhancements in ProTRAK® provide straight and rigid legs, making it the best choice for framing walls, headers, soffits, and bulkheads
Design Advantages
N/A
Designed to meet the additional strength requirements of today's building codes: IBC 2015, AISI (S100), ICC-ES AC86 (2015)
Smart Edge™ Technology is an enhancement for producing easier-to-handle steel that reduces the risk of cuts and scrapes
UL Classified and listed in over 50 designs, including U419, V438, and chase wall assemblies
Exceptional sound performance in over 30 tested sound assemblies
Can contribute LEED® points in LEED v4 or LEED 2009. EPD and HPD verifications also available.

Calculated properties are based on AISI S100-12, North American Specification for Design of Cold-Formed Steel Structural Members and AISI S220-15, North American Standard for Cold-Formed Steel Framing-Nonstructural Members.
Effective properties incorporate the strength increase from the cold work of forming as applicable per AISI A7.2.
Tabulated gross properties, including torsional properties, are based on full-unreduced cross section of the studs, away from punch outs.
Tabulated gross properties, including torsional properties, are based on full-unreduced cross section of the tracks.
For deflection calculations, use the effective moment of inertia.
Allowable moment includes cold work of forming.
Allowable moment is taken as the lowest value based on local or distortional buckling. Distortional buckling strength is based on a k-phi = 0.
Web depth for track sections is equal to the nominal height plus two times the design thickness plus the bend radius. Hems on nonstructural track sections are ignored.
