Square thread - Import export

SPIROL specializes in the manufacture of precision machined AAR Nuts for the railroad industry. SPIROL's Railroad Nuts are held 100% square to the tap. SPIROL's thread pitch diameter allowances are engineered for ease of assembly after plating, yet manufactured to strict standards with specific gages. Each production lot has a unique identification number and is traceable through each manufacturing process back to the original raw material test certificate. SPIROL's Railroad Nuts, otherwise referred to as AAR Clamp Nuts, Binding Nuts, and Gold Test Nuts or AAR Signal Nuts are used in signal lights, crossing bells and terminal blocks.
