Bolt & Nut Assembly with Plastic Washer

The bolt and wingnut set, including washers, is the standard and fundamental fastening system in technical diving for assembling modular systems. This set is specifically designed to securely, solidly, and stably connect the backplate to the wing, battery canister holders, or single tank adapters (STAs).

The kit includes special plastic washers, a crucial and highly recommended accessory when using aluminum or carbon fiber backplates, as they prevent scratches, friction wear, and galvanic corrosion between different metals.

Key Features and Technical Specifications:

• Marine Grade Stainless Steel: The bolt and wingnut are entirely made of high-quality stainless steel, designed to withstand prolonged corrosive action from saltwater and ensure a perfect structural hold over time.
• Protective Plastic Washers: Included in the set, they create an insulating and cushioning layer between the metal of the bolt and the plate surface, preserving the integrity of lightweight or composite materials.
• Wingnut Design: Allows for quick hand-tightening and removal without the need for specific tools at the dive site.
• Weight Specifications: Only 26 g for the entire set (bolt, wingnut, and washers), ideal for keeping the configuration light, especially for travelers.
  

Available Bolt Lengths:

Choose the perfect size for your setup from the drop-down menu:

• 20 mm (2 cm) Length: Ideal for minimalist configurations and direct low-profile couplings.
• 25 mm (2.5 cm) Length: The most versatile standard size for most wings and backplates on the market.
• 30 mm (3 cm) Length: Perfect for thicker setups, where additional accessories such as single tank adapters (STAs), accessory plates, or heating systems are installed.

Main Fields of Use:

• Backplate / Wing Attachment: Connects the steel, aluminum, or carbon backplate to the buoyancy compensator (wing).
• Single Tank Adapter (STA) Mounting: Secures the adapter to the backplate for quick switching from twinset to single tank configuration.

Target User:

This fastening set is an essential accessory for technical, exploration, and advanced recreational divers who use back-mounted buoyancy systems. It is the preferred choice for those with aluminum or carbon plates who desire lightweight, rust-resistant hardware that protects the more delicate materials of their harness.
