1 Shank code applicable only to Types U and UL fasteners.
2 In applications between the sheet thicknesses for your thread size, see last paragraph of installation data on page FE-6. Knurled collar may
fracture if fastener is used in sheets thicker than the specified range and the screw is tightened beyond maximum
3 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
