Snap-On SW-426 1/2 Inch Drive 13/16 Inch 8 Point Socket

Snap-On SW-426 is a 1/2" drive SAE 13/16" 8-point socket, part of Snap-On’s vintage double-square socket family. The 13/16" size identifies the fastener it is designed to engage, and the 8-point geometry aligns with eight-point fasteners when used with a standard 1/2" drive ratchet. Known entries in Snap-On’s historical catalogs place SW-426 in the mid-20th century, with production dating roughly from 1953 to 1978, which is why collectors often reference this model as part of the era’s tool lineup. Use SW-426 whenever you encounter a 13/16" eight-point fastener and you’re working with a 1/2" drive tool, ensuring the fastener tends to nominal size for proper seating and to avoid slippage. This socket exemplifies Snap-On’s tradition of precise fit and interchangeability within a 1/2" drive system, making it a purposeful choice for assemblies and maintenance tasks where a dedicated 13/16" eight-point socket is required.
