M18 Wing Nut DIN 315 -A4 Stainless Steel (316 Marine Grade) -66.5mm Wide
The M18 A4 Stainless Steel Wing Nut at 66.5mm wide is one of the largest sizes in this range -also known as a butterfly nut or thumb nut, manufactured to DIN 315 and designed for the largest common structural applications -major plant access hatches, heavy civil engineering frameworks and large marine fittings requiring a substantial butterfly nut. The two large wings allow the nut to be tightened and loosened by hand without any tools -essential wherever the fastening needs to be adjusted, inspected or removed regularly without stopping to find a spanner.
A4 stainless steel (grade 316) is the marine and offshore grade -the molybdenum content makes it significantly more resistant to chloride attack than A2, which is essential in coastal, marine, offshore and chemical processing environments at this heavy structural size. The 66.5mm wide wing profile and 31.2mm height ensure adequate hand-tightening torque even on heavy structural fastenings. A countersunk bearing face distributes clamping load across the surface. DIN 315 compliant for use with any M18 bolt or threaded rod at 2.5mm pitch.
Common Applications
- Major plant and infrastructure access hatch tool-free retention
- Heavy civil engineering and large structural framework fastening
- Large marine and coastal fitting hand-tightened assembly
- Heavy industrial equipment guard and cover fastening
