RE: Strength of 1/4-14 Sheet Metal Screws in 12g SS Screwman (Mechanical) 12 Dec 08 16:41 It's not the strength of the screws that is so questionable (although they are pretty questionalbe from a mechanical standpoint too), it's the unknown strength of the one "thread" that is formed into the sheet metal. The tabulated ASD and LRFD allowable loads for cold-formed steel (CFS) members are based on the lower of the screw strength or the strength of the screw in the connected members per AISI S100. Figure 8. 134 lb. Minimum screw spacing is three (3) times the nominal screw diameter. Loaded end distance in these tests was one inch. DESIGN THICKNESS OF STEEL SHEET NOT IN CONTACT WITH THE SCREW … Fasten sheet metal up to 0.200" thick. Screw diameters per AISI S200 General Provisions Commentary Table D1-1. Metal alloys are often stronger than a metal in their pure form. Screws and screw connections have been tested per AISI Standard Test Method S904 and S905 with the exception of 22-gauge values which are based on calculations of the AISI S100. 2The load-bearing area is the threaded portion of the screw that is heat-treated to HRC 30-34. * 16d sinker .148” 115 lb. This is especially true in construction, transportation, heavy industry and tool making. Value Fastener stocks Type A, Type AB, High-Low and Type B sheet metal screws. Sheet metal screws typi-cally have higher ultimate load than wood screws … See additional Load Tables, Technical Data and Installation Instructions for the Strong-Drive® Self-Drilling X Metal screw.

Tapcon Screw Anchor - Technical Data Ultimate Tension and Shear Values (Lbs/kN) in Concrete ... 1 CMU = 1,600 PSI minimum compressive strength. Yes there is a limit to the screw strength. Material Strengths (Part 1) Material strength for threaded fasteners and headed industrial fasteners from Elgin Fasteners Group is listed below by grade, type and class and separated into 60,000 psi, 75,000 psi and 120,000 psi. Pull-out test results for 6061-T6 screw slots with 1/4” screws. Minimum screw spacing is three (3) times the nominal screw diameter. Screws and bolts also differ in shape and cost — screws are often tapered, while bolts are not, and bolts tend to cost more than screws.
