Key Features

Flat head with nibs for easy countersinking
#3 square drive (driver bit in each box; replacement bit model BIT3S; use BIT3SU for Mechanically Galvanized — N2000^®)
#4 drill point with wings for general duty applications
Straight collation

Applications

Wood to steel (maximum recommended metal thicknesses: 1/4")

Warning

Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, use this product in dry, interior, and noncorrosive environments only.

These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated woods. For applications in higher-exposure applications, consider type-300 series stainless-steel fasteners for superior corrosion resistance. See additional important information before selecting a fastener for a specific application.

Load Tables

TB — Allowable Loads — DF and SP Lumber Attachment to Steel (Steel Members 16 ga.– 5/16" Thick)

For use with structural steel members up to 5/16" thick or cold-formed steel members 54 mil (16 ga.) or thicker.
Minimum steel strength Fu = 45 ksi.
Standard product available in a black phosphate coating. Mechanically galvanized (N2000) coating available for additional corrosion protection.
Reference allowable loads are based on tests using 2x (1.5 in.) thick wood members.
Use increased allowable loads (C_D = 1.6) only when resisting wind or seismic forces. Values must be multiplied by all applicable adjustment factors per the NDS.
Minimum fastener spacing requirements to achieve allowable loads: 4" end distance, 1.5" edge distance, 1.5" between staggered rows, 3" between non-staggered rows, and 4" between fasteners in a row.
