Highland Delrin Speed Nuts 5/16 8mm

Ditch the tools and prevent seized threads on your technical rig. Threading standard stainless steel wing nuts onto backplate carriage bolts can be frustrating—especially on a crowded dive boat or when using cold-water drysuit gloves. Highland Delrin Speed Nuts offer a lightweight, corrosion-free, and tool-free solution for securing your backplate to twinset bands or single tank adapters (STA).

Machined from heavy-duty engineered Delrin acetal resin, these oversized coarse-threaded nuts feature an ergonomic knurled barrel design that allows you to hand-tighten your rig rock-solid in seconds.

✨ KEY FEATURES & BENEFITS

⚙️ 100% Saltwater Corrosion Resistance: Made from solid machined Delrin (acetal resin), these nuts will never rust, pit, or gall against stainless steel bolts, completely eliminating seized or frozen threads.

✋ Tool-Free Hand Tightening: The wide, ergonomic diameter paired with deep exterior knurling gives you maximum leverage. Torque your backplate down securely using just your fingers—no pliers or wrenches needed on the boat deck.

???? Glove-Friendly Tactical Design: Engineered specifically with cold-water and technical divers in mind. The oversized barrel shape is effortless to manipulate even while wearing thick 5mm neoprene gloves or drysuit dry-gloves.

???? Stainless Steel Threaded Inserts: Features precision-cut stainless steel interior threads embedded into the Delrin housing, delivering maximum clamping force without stripping or cross-threading under load.

???? Industry Standard Thread Pitch: Designed with standard 5/16"-18 thread size, making them universally compatible with almost all technical backplates, twinset band bolts, and single-tank adapters (STA) on the market.
