AMSI#12 SCREWS ULTIMATE VALUE CHART
|Diameter||Nom. Screw Diameter (inches)||Metal Gauge/1lb||Tension (Pull) lbs 1pc||Shear (lbs) Metal to Metal||Minimum Torsional Strength (lbs)|
ULTIMATE VALUE CHARTS:
Steel: Screws are driven into steel were driven with three (3) exposed threads on the off-side of the connection, then pulled out with the testing machine.
Wood: Screws were driven 3/4" into the wood material then pulled out with the testing machine.
Note that all results were obtained in strict adherence to ASTM test protocols. These ultimate figures are offered only as a guide and are not guaranteed in any way by AMSI (Architectural Metal Specialties Inc.). A 4:1 safety ratio is recommended.
0-2500rpm screwgun with torque adjustment is recommended. Overdriving may result in fastener failure or strip-out of the work surface.
The fastener is fully seated when the screw head's bearing surface is flush with the surface.
Always were eye protection when driving screws. Screws and driver bits may fracture or shatter. Serious injury and/or blindness can occur.
