S&H Industries 77133 Thread Adapter to Electronic Ignition System - 1/2-13 1/2-20

The S&H Industries 77133 is a precision-engineered thread adapter designed to convert between two common thread standards. This adapter features 1/2-13 UNC (Unified National Coarse) threading on one end and 1/2-20 UNF (Unified National Fine) threading on the other end, allowing you to connect components with different thread pitches.

Key Features:

• Dual-thread design: 1/2-13 UNC to 1/2-20 UNF conversion
• Precision-machined threads for secure, reliable connections
• Durable construction for automotive, industrial, and mechanical applications
• Compact design for space-constrained installations

This thread adapter is ideal for hydraulic systems, brake line conversions, fuel system modifications, and general mechanical assemblies where thread pitch compatibility is required. The adapter provides a solid connection point between components with mismatched threading standards.
