Product Description
A Wing Nut enables easy tightening and removal by hand. Use wingnuts to secure an access panel,
marine hardware or in other situations where handling a wrench is inconvenient. Use a zinc-plated
stainless steel wing nut for exterior applications since their extra surface area makes them vulnerable
to corrosion.
Metric DIN 315 Wing Nuts / Butterfly Nuts of the German Type have two rounded wing like projections.
This unique design makes it possible to use your thumb and forefinger to turn and tighten the nut rather
than a having to use a wrench or other tool thus ensuring easy rapid assembly and disassembly using
only fingers. DIN 315 wing nuts can be used for many applications where quick hand tensioning
and clamping is required. QBH company offers the following sizes for immediate delivery from stock:
Diameters ranging from M4 to M24 in steel and stainless steel A2 and A4.
Stainless steel(SS304/SS316)
Made from 316 stainless steel, these wing nuts have excellent chemical resistance and can be used in saltwater
environments. The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.
Carbon steel
Wings provide more leverage for greater torque while tightening than knurled-head thumb nuts. Zinc-plated wing nuts
are corrosion resistant in wet environment.
Brass
These wing nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.
The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Company Profile
Jiaxing City Qunbang Hardware Co., Ltd. (brand: QBH) is a fastener enterprise integrating production, design, sales, and after-sales service. The company is located in the Hangzhou-Jiaxing-Huzhou Plain, close to Shanghai, Ningbo, and Zhapu ports. Thanks to its superior geographical position and convenient transportation, the company has natural advantages for export business.
The company mainly produces high-strength fasteners, with bolts and nuts as its core products. The main standards include DIN, ANSI/ASME, JIS, UNI, ISO, AS, BS, GB, and others. Our products are widely used in bridges, roads, petroleum pipeline facilities, wind power generation, and steel structure projects. Carbon steel bolts are available in grades 4.8, 5.8, 6.8, 8.8, 10.9, and 12.9; Nuts in grades 4, 6, 8, and 10. Stainless steel fasteners are mainly made of 201, 304, and 316. Since its establishment, QBH has undergone over ten years of development. We are equipped with comprehensive testing equipment and maintain good cooperation with SGS and TUV. Each batch of products is accompanied by a 3.1 or 3.2 certificate, further ensuring quality.
In 2017, we registered the trademark "QBH" in China, the EU, and the United States, and obtained six fastener product patents. We have also been awarded the Zhejiang Province Science and Technology Small and Medium-sized Enterprise certificate and the ISO9001: 2000 certificate. As the company continues to grow and customers demand more diversified products, we have further strengthened our manufacturing capabilities.
In 2025, QBH officially expanded with two new factories:
China Factory (Ningbo):
