SNC / SNF / SNS Series SPLITNUTS – Two-Piece Clamping Nuts

A splitnut does what a clampnut does — self-locks with a tangential socket head clamp screw — but in two pieces, so it assembles around the shaft instead of threading down it. That matters when the thread is mid-shaft, damaged at the end, or blocked by a component that would otherwise have to come off. SNC covers UNC coarse threads, SNF covers UNF fine threads and SNS covers the 16 TPI UNS series; all three are stocked in carbon steel and stainless (S suffix).
