Vimal Industrial Corporation is a trusted stockist and supplier of DIN 315 A Wing Nuts with Rectangular Wings—precision-engineered for tool-free fastening and quick adjustments—based in Mumbai, India. Manufactured to the DIN 315 A standard, these wing nuts feature wide rectangular wings for improved grip, allowing operators to tighten or loosen connections by hand without tools.
Available in stainless steel, carbon steel, and brass, DIN 315 A wing nuts are widely used in assemblies that require frequent disassembly, fine adjustment, or lightweight fastening solutions. Each nut is produced with accurate thread tolerances, robust wing geometry, and consistent surface finishes to ensure reliable performance in diverse industrial and commercial environments.
DIN 315 A specifies wing nuts with rectangular wings and standard metric threads. These nuts are designed to:
Enable manual tightening and loosening without tools.
Provide a large gripping surface for better torque application.
Support quick assembly and disassembly in maintenance-intensive setups.
Function in tight spaces where standard hex nuts are impractical.
Available in multiple property classes for general-purpose and high-strength requirements, as well as stainless grades for chemical, food-grade, and outdoor applications, DIN 315 A wing nuts can be supplied in plain/oiled, zinc-plated, hot-dip galvanized, black oxide, and PTFE-coated finishes to meet varied environmental and service-life demands.
With the growing demand for quick-adjustment fasteners in machinery, fabrication, furniture, and marine industries, DIN 315 A wing nuts are an essential choice for OEMs, MRO workshops, and project contractors.

The tensile strength depends on the property class and material. For example, stainless steel grades A2-70 and A4-70 have tensile strengths of 700 N/mm², while high-strength alloy steel in property class 12.9 can reach up to 1200 N/mm².
Property Class refers to the mechanical strength rating of a fastener, indicating its tensile strength, yield strength, and hardness. Common classes for wing nuts include 4.8, 5.6, 6.8, 8.8, 10.9, and 12.9.
A2 (304 stainless): General-purpose corrosion resistance, suitable for most outdoor applications.
A4 (316 stainless): Higher corrosion resistance, especially in marine and chemical environments due to molybdenum content.
Hardness values vary by material and property class:
Vickers Hardness: ~130–435 HV
Brinell Hardness: ~124–412 HB
Rockwell Hardness: HR 71–HR 99, or HRC 20–39 depending on class.
Chemical composition determines corrosion resistance, mechanical strength, and suitability for different environments. For example, A4 stainless steel contains higher nickel and molybdenum, enhancing performance in aggressive environments.
