DIN316 Butterfly Wing Bolts

Butterfly Wing Bolt Product Describsion

Butterfly wing bolts are Boltead’s main product. We are a manufacturer and also a supplier of butterfly the bolts. While producing and supplying butterfly these bolts, we also produce nuts, washers and other fastener products used in conjunction with them.

The butterfly wing bolts we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:

Carbon steel butterfly wing bolts are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, bolts with grade 8.8 or above are generally called high-strength bolts （high tensile bolts）.Stainless steel butterfly wing bolts are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316

In addition to different materials and strengths, the biggest impact on butterfly wing bolts is surface treatment. The following are the more common surface treatments for these bolts: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

Butterfly Wing Bolts Production Process

Butterfly wing bolts are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:

Butterfly Wing Bolts Application fields

Butterfly wing bolts have a wide range of applications in various industries and settings. Some common applications include:

• Wing bolts are commonly used in applications where frequent adjustments or quick assembly and disassembly are required, such as in furniture manufacturing and assembly.
• They find extensive use in various fixtures, clamps, and mounting applications, providing a convenient hand-tightened fastening solution in place of traditional tools.
• Wing bolts are often employed in equipment and machinery setups where rapid installation or adjustment of components is needed, particularly in industrial and manufacturing environments.
• They are utilized in woodworking and carpentry for jigs, fixtures, and other temporary fastening needs due to their easy hand-operated tightening.
• Additionally, wing bolts find application in recreational equipment, automotive accessories, and DIY projects where tool-less fastening solutions are advantageous.

These bolts are versatile and can be used in many different situations where a secure and durable fastening solution is required.
