Auveco Butt Terminals: Professional-Grade Wire Connections Built to Last

When a wiring repair demands a connection that holds up under heat, vibration, and the relentless demands of daily driving, the quality of your butt terminal matters more than most technicians realize. Auveco — a brand with over a century of engineering expertise behind it — brings that same exacting standard to its line of butt terminals, making them a trusted choice for professional mechanics, collision repair shops, and serious DIYers alike.

A Century of OEM-Quality Electrical Hardware

Founded in 1916, Auveco (short for Auto-Vehicle Parts Co.) has spent more than 100 years manufacturing and distributing specialty automotive and industrial fasteners and hardware. The brand's catalog — often referred to in the industry as "The Encyclopedia of the Automotive Body Hardware Industry" — spans tens of thousands of parts, and their butt terminal lineup reflects the same depth of coverage. Every connector is manufactured to meet or exceed OEM specifications, so technicians can trust that a repaired circuit will perform just like the factory original.

What Sets Auveco Butt Terminals Apart

Auveco's butt terminal range is notable for the variety of connection technologies and wire gauges it covers. Key product types include:

• Crimp and Solder Butt Connectors — A dual-action design (such as SKUs 21002, 21003, 21004, and 21005) that allows the connector to be both crimped and soldered for a superior mechanical and electrical bond. These are available across a wide gauge range, from fine 24–22 AWG signal wires all the way up to heavy 12–10 AWG power circuits.
• Crimp and Solder Step-Down Butt Connectors — Designed for splicing wires of different gauges together (for example, stepping down from 16–14 AWG to 12–10 AWG), these connectors solve a common challenge encountered during wiring harness repairs and upgrades.
• Non-Insulating Butt Connectors — Bare connectors for applications where a separate sleeve or heat-shrink wrap will be applied, offering flexibility for specialized installations across a range of gauges including 22–18 AWG.
• Flared Butt Battery Cable Connectors — Heavy-duty options such as the 2/0 gauge flared design (SKU 11729), engineered specifically for high-current battery cable splicing where a robust mechanical connection is non-negotiable.

Designed for Professionals, Trusted by Enthusiasts

Auveco's butt terminals are not one-size-fits-all commodity parts. The lineup covers an exceptionally broad gauge spectrum — from the finest automotive signal wires to the largest battery cables — making it straightforward to find the right connector for virtually any electrical repair scenario. The crimp-and-solder variants are especially valued in professional settings because the dual mechanical and thermal bond significantly reduces the risk of connection failure from vibration or corrosion over time.

Whether you are splicing a broken tail-light circuit, repairing a damaged wiring harness after a collision, or building a custom electrical system from scratch, Auveco butt terminals deliver the reliable, OEM-matched performance that professional shops depend on.
