Brass Pile Head Battery Quick Release Clamp Pure Copper Tin Plated Positive 17.5mm Negative 15.9mm Wiring 5.2-7.4mm AWG 1-4 Connect Battery and Wire Automotive Marine
Brass Pile Head Battery Quick Release Clamp for Secure Connections

This brass pile head battery quick release clamp simplifies the process of connecting a battery to wiring. Designed for automotive, marine, and other 12V or 24V applications, it allows for rapid attachment and removal without the need for tools. The clamp is constructed from pure copper with a tin-plated finish to support consistent electrical conductivity and resist corrosion. Supplied as a pair, it includes one positive terminal (17.5mm) and one negative terminal (15.9mm), suitable for a range of battery posts.
Features and Construction

The clamp is built around a straightforward design that prioritises ease of use and reliable electrical contact. Each component serves a specific purpose in ensuring a secure connection that holds under vibration and regular use.
Material and Build
The clamp body is made from pure copper, a metal chosen for its excellent electrical conductivity. The tin plating adds a protective layer that helps prevent oxidation and corrosion, which is particularly beneficial in damp or engine-bay environments. The brass pile head provides a robust contact surface for the battery terminal.
Size and Practical Fit
Two distinct sizes are provided in the pair: 17.5mm for the positive terminal and 15.9mm for the negative terminal. These dimensions correspond to standard battery post sizes found in many vehicles and equipment. The wiring entry accepts cable diameters from 5.2mm to 7.4mm, which covers AWG sizes 1 through 4 or cable cross-sections from 16mm² to 35mm².
Uses and Placement

The clamp is suited to any application where a secure, releasable battery connection is needed. Its quick-release mechanism makes it a practical choice for situations where batteries are frequently disconnected and reconnected.
Event or Professional Use
In automotive workshops, race pits, or marine servicing, a battery clamp that can be removed quickly without tools speeds up battery changes and diagnostic work. The positive and negative colour or size differentiation (17.5mm vs 15.9mm) helps prevent reverse polarity connections during fast-paced work.
Everyday Home Use
For owners of classic cars, boats, or off-grid power systems, this clamp provides a straightforward way to maintain battery connections. The tool-free operation is convenient for seasonal battery storage or when replacing a battery in a car, caravan, or lawn tractor.
Benefits and Buying Value

The value of this product lies in its simplicity and the quality of its electrical materials. There are no complex parts to fail, and the copper construction supports reliable current flow.
Reuse and Low Maintenance
Because the clamp uses a mechanical lever or screw mechanism (quick release), it can be reused many times. The tin-plated copper resists corrosion, reducing the frequency of cleaning. Keeping the contact surfaces clean will maintain good performance.
Why Choose This Product
If you need a battery clamp that combines quick-release convenience with solid copper construction, this pair offers a direct solution. The clear size difference between positive and negative terminals and the wide cable acceptance range make it a versatile addition to your toolkit or spare parts inventory.
