This refers to the 300 series of stainless steel with a chromium and nickel content in percentages. That means that an 18-8 grade fastener has 18% chromium and 8% nickel content. 18-8 type stainless steel has better resistance to corrosion than the 400 series. It can be hardened only by cold working, and it isnt magnetic.
These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance. High-Strength 410 Stainless Steel Hex Head Drilling Screws for MetalStainless Steel Information Knowledge | 18-8 | 304 | 316 18 8 screw strengthType 304 (18-8) is an austenitic steel possessing a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is a nonmagnetic steel which cannot be hardened by heat treatment, but instead. must be cold worked to obtain higher tensile strengths. The 18% minimum chromium content provides corrosion and oxidation resistance.Stainless Steel Grades - Portland BoltJun 30, 2010 · Grades within the 18-8 family of stainless alloys have a minimum tensile of 75,000psi, so the shear strength would be roughly 45,000psi. If you multiply that by the stress area of the screws, that will give you the shear strength of the screws.

Precision assembly work and applications requiring a well-tooled appearance. Greater tensile strength than same size Grade 5 or 8 hex head cap screws while requiring less surface area due to the internal wrenching. Stainless socket screws have less tensile and yield strength than alloy sockets, but superior corrosion resistance.Shear values for deck screws and drywall screws. | The 18 8 screw strengthOct 25, 2011 · I have hung more than a few wall cabinets with only two screws and watched people fill up those cabinets with their antique ceramic dishware. My calculations and assumptions for a #8 screw: Diameter with threads excluded from the shear plane = 0.164" Radius = 0.082" Area in shear plane = pi x radius ^ 2 = 0.0211 square inches x 36,000 psiSelf-Drilling Screws | FastenalSelf-drilling screws enable drilling without first creating a pilot hole. These screws are usually used to join materials like sheet metal.
As the distance increases, the pullout strength of the same screws decreases. For example, screws set 18 inches apart in a half-inch piece of plywood have only 63 percent of the pullout strength (71 psf) of screws set 9 inches apart (113 psf). Those screws will have even less strength Proof Load Tensil Strength For Grade 2, 5, & 8Tensile Strenght: Proof Load Tensile Strength for Grade 2, 5, & 8,Metric Bolt Grades and Strength CalculatorMetric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.
