Facom 1/2 - 3/8-inch Coupler

Facom 1/2 - 3/8‑inch Coupler: Precision Conversion for Hand Tools

The Facom 1/2 - 3/8-inch Coupler, also known by its model number S.230, is a high‑performance adapter that bridges the gap between a ½‑inch female socket and a ¾‑inch male socket. Designed for professionals who demand reliability and durability, this coupler enables seamless use of larger 3/8‑inch sockets on tools that originally accept only 1/2‑inch sizes.

Key Features & Technical Specifications

• Female Thread: ½‑inch (ISO 68-1)
• Male Thread: ¾‑inch (ISO 68-1)
• Material: Hardened steel with a chrome‑plated finish for corrosion resistance
• Torque Capacity: Up to 212 Nm, suitable for heavy-duty applications
• Thread Pitch: 1.5 mm (M6) on the female side, 2.0 mm (M8) on the male side
• Length: Approximately 33.5 mm from end to end
• Weight: Lightweight construction for easy handling during repetitive tasks

Design Philosophy

The Facom coupler embodies the brand’s commitment to ergonomics and precision engineering. Its compact profile minimizes bulk, allowing users to maintain a natural grip on the tool while still accessing larger socket sizes. The chrome plating not only protects against rust but also provides a smooth surface that reduces friction during torque application.

Applications & Use Cases

• Automotive Repair: Quickly switch between 1/2‑inch and ¾‑inch sockets when working on engine components, suspension parts, or brake systems.
• Industrial Maintenance: Ideal for machinery that requires a mix of socket sizes without changing the entire tool set.
• Bicycle Mechanics: Enables use of larger 3/8‑inch hex keys on tools originally designed for 1/2‑inch, improving efficiency during frame assembly or wheel truing.
• Precision tasks that demand high torque and reliable thread engagement benefit from the coupler’s robust construction.

Installation Guide

1. Align the ½‑inch female end of the coupler with the socket on your tool.
2. Screw the coupler onto the tool until it is fully seated, ensuring no cross‑threading.
3. Attach a ¾‑inch male socket to the other end of the coupler.
Use a torque wrench set to the desired value (up to 212 Nm) for final tightening.

Maintenance & Care

• After each use, wipe the coupler with a clean cloth to remove grease or debris.
• If corrosion appears, gently polish the chrome surface with a non‑abrasive cleaner.
• Store in a dry environment to prevent moisture buildup.
