The extruded U-nut shall fit onto 0.050-inch and 0.200-inch thick test panels and fit into holes drilled for 38-inch fasteners. When the extruded U
7、-nut is assembled onto 0.050-inch and 0.200-inch thick test panels having 516-inch diameter holes located with their centers 1 inch from the edge, the retaining feature shall locate in the holes and a minimum pull force of 3 pounds shall be required to remove the nut from the test panel. 2.5 Threads
8、. The threads shall conform to 38-inch 16 UNC-2B thread form per ASME B1.1. 2.6 Proof load. The extruded U-nut shall be able to be easily removed after being exposed to a 9,300-pound force bolt. The extruded U-nut shall be assembled onto a test panel and a test bolt shall be installed with a minimum
9、 of three threads projecting through the extruded U-nut. The test bolt shall have a yield strength sufficient to develop a proof load of 9,300 pounds. A tensile load of 9,300 pounds shall be applied to the nut through the test bolt in the axial direction. The threaded sleeve shall resist this load w
10、ithout thread stripping, excessive plastic deformation, or rupture. The bolt shall be removable from the nut with fingers once the load is released. A hand wrench may be used for the first one-half turn. 2.7 Protective finish. The extruded U-nut shall be coated with a phosphate and oil finish in acc
11、ordance with ASTM F1137, Grade 0D, or Ford ESS-M3P20-A (S2), or GM 4435-M, Code A. 2.8 Workmanship.
