{"product_id":"wing-nuts-a4","title":"Wing Nuts M4–M6 — A4 Marine 316 Stainless DIN 315","description":"\u003ch3\u003eWhy choose these Wing Nuts\u003c\/h3\u003e\n\u003cp\u003eOur Wing Nuts are manufactured from A4 (316) marine grade stainless steel to DIN 315 — the European standard for German-pattern wing\/butterfly nuts. The two flat wings are sized to grip firmly between thumb and forefinger, so the nut can be tightened, released and re-fitted by hand without a spanner. A4-316 contains added molybdenum that gives substantially better resistance to chloride corrosion than A2, making these nuts the right choice for marine, coastal and chemical-exposure environments where a standard stainless nut would still pit and stain.\u003c\/p\u003e\n\u003ch3\u003eSizes available\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eM4 \/ 4mm — small fixtures, brackets and equipment covers\u003c\/li\u003e\n\u003cli\u003eM5 \/ 5mm — garden furniture, signage and light fabrication\u003c\/li\u003e\n\u003cli\u003eM6 \/ 6mm — marine deck fittings, handrails and general workshop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePack options\u003c\/h3\u003e\n\u003cp\u003eEach size is available as a single unit sample, or in packs of 10 or 20.

For applications that see vibration or where the nut must stay tight under load, pair with a plain washer or use alongside a primary nut as a finger-adjustable backup. The bolt thread should be clean and undamaged for smooth hand-tightening.\u003c\/p\u003e\n\u003ch3\u003eDelivery\u003c\/h3\u003e\n\u003cp\u003eSame-day dispatch on orders placed before 2pm, Monday to Friday.
