Aluminum 3003-H4 Square Tubing, ASTM B210, 7/32" x 7/32", 0.014"

Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials. Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials. With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels.

Fine threads are preferable when working with harder materials or when threading into a thin material. Fine threads are preferable when working with harder materials or when threading into a thin material. Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. There's not much left to the imagination that the specs don't already provide - these are just high quality fasteners, which I happened to snap up at the right time.
