Seamless Steel Pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Steel Tubing is a hollow steel shape intended for structural purposes and made from carbon, stainless, or galvanized steel further divided as:
Mechanical Tubing is used in low stress applications such as fences, kitchens, restaurants, hospitals, solar panels and made with wall thicknesses up to 10 gauge.
Structural Tubing is for high stress structural application like bridges, buildings, roll cages, and underwater platforms with wall thickness from 3/16" and up. It is often referred to as Hollow Structural Sections or just the acronym HSS.

Product Description
Socket head screws used in machinery, mainly for fastening, disassembly, it is not easy to slip Angle and other advantages. Allen wrench is usually a 90 ° bend, bend at one end of the long and short, with a short side of the screw, holding a long side can save a lot of power and better tighten screw. Long runs round head at one end (hexagonal cylindrical similar sphere) peace head, round head can be easily inserted into the screw hole is very convenient disassembly, the outside hexagonal manufacturing costs less than Allen, its advantages and screw head (wrench stress location) thinner than Allen, in some places is not Allen can replace. Also the cost is low, dynamic strength is small, low accuracy of machine adopt socket head screw is much less than the outer hexagon.
