Cold-Formed Steel Member Connection Loads, Steel-to-Steel
Screws and their connections have been tested per AISI Standard Test
Method S904-08 and S905-08.
Loads are based on cold-formed steel members with a minimum yield
strength, Fy = 33 ksi and tensile strength, Fu = 45 ksi for 43 mil (18 ga.)
and thinner, and a minimum yield strength, Fy = 50 ksi and tensile strength,
Fu = 65 ksi for 54 mil (16 ga.) and thicker.
Screws shall extend through the connection with a minimum of three exposed
threads per AISI General Provisions Standard Section D1.3.
Screw Strength (lb.)
Pss — Shear strength
Pts — Tensile strength
Allowable Loads for Connectors in Trex Elevations
Loads are for one part only.
Loads are for 8" headers/joists.
F1 load refers to the download or the uplift loads acting along
the web of the joist/header.
