  • Cross Pin will withstand 50 lb pushout force and retain sym. about centerline of stud within .02
  • For Stud selection and Installation data see 4002 series
  • Tool marks may appear at swage area due to the nature of assembly process
    For -21 and longer use
    L/L1 min = (Dash No. x .030) + .353
    Lmax = Lmin + .010
    L1max = Lmin + .015
    S = (Dash No. x .03) + .63
    Approximately weight = lb/100
    Suffix None/B = .930 + (Dash No. x .0195)
    Suffix A = 1.582 + (Dash No. x .0195)
