Blind Molly Thread Jack Rivet Nuts For Sale

What is Jack Nut/ Molly Threaded Insert?

A jack nut, also known as a molly thread insert, is a type of fastener used to create a threaded hole in materials where it would be difficult or impossible to access the opposite side for traditional nut and bolt assembly. It consists of a threaded insert with a flanged head. The flange prevents the nut from being pulled through the material, while the threaded portion provides a secure grip when a bolt or screw is inserted. 

Jack nuts are commonly used in applications such as thin sheet metal, fiberglass, plastic, or other materials that do not have enough strength to hold a traditional nut. They offer a reliable and convenient way to create a strong threaded connection in these challenging situations. Installation is typically done using a special tool that expands the jack nut, allowing it to grip the material securely.

Overall, jack nuts provide an efficient alternative to traditional nuts and offer enhanced versatility for creating threaded connections in challenging situations or thin materials.

Material Used for Jack Nut

Jack nuts are generally made from various materials to suit different applications. Some common materials used for jack nuts include:

• Steel: Steel jack nuts are widely used due to their high strength and durability. They are suitable for applications where a strong threaded connection is required.
• Brass: Brass jack nuts are popular for their corrosion resistance and electrical conductivity. They are often used in electrical and electronic equipment, as well as in marine environments.
• Stainless Steel: Stainless steel jack nuts offer excellent corrosion resistance and are suitable for applications where exposure to moisture or chemicals is expected. They are commonly used in outdoor or corrosive environments.
• Aluminum: Aluminum jack nuts are lightweight and have good corrosion resistance. They are often used in aerospace, automotive, and lightweight construction applications.
