We had 10,000 pieces of each size of these custom stainless steel fully threaded lag screws supplied to our construction customer. 304 stainless steel material was used and the parts were manufactured to ASME B18.2.1 other than the full thread feature requirement. Tensile strength was required to surpass the minimum 90,000 psi requirement and both the material composition and the tensile strength (axial) were tested at a third party lab with full certs. The two sizes pictured here are the 3/8-7 X 4" and 3/8-7 X 5.5". The finish on both sizes is Geomet 321 with Plus L top coat.
