thread inserts

Thread Insert Details

Thread inserts, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or simplify changeover from unified to metric threads or vice versa.Thread insert is one of captive nut.

An insert nut provides a threaded socket for a wooden workpiece, similar to a wall anchor. Insert nuts are inserted into a pre-drilled hole by one of two means: screw in and hammer in. In both cases, the external protrusions bite into the wood, preventing the nut from either turning or pulling out.
Insert nuts are advantageous over barrel nuts and T-nuts, because they can be installed from one side of the workpiece.

Thread inserts are used in a wide range of applications. As a example, in addition to airplane manufacturing, they are used in automotive manufacturing to fasten body parts together or attach molding and for body repairs. They are used in consumer electronics to fasten together plastic components or to secure circuit boards, and in boatbuilding to secure fiberglass and to create waterproof joins. For furniture making,as we said furniture thread nuts, threaded inserts are ideal to secure soft wood parts. Any application for which you need a strong join can benefit from a threaded insert. They also are commonly used to repair stripped holes.

thread inserts application

There are so many types of thread inserts and insert nuts are that they are used for a wide range of applications with different types of materials.

Plastics, for ,as a example, tend to be soft and brittle, but often need a fastener that can withstand assembly and disassembly multiple times. Jack nut inserts are commonly used because they have a wide footprint and create a strong insert without damaging the plastic. Fiberglass presents a similar challenge; jack nuts are frequently used for thin sheets of fiberglass, but for thicker sheets, such as those used in boatbuilding, knurled inserts provide a solid joint and wellnut inserts create a vibration-proof and waterproof joint.

Tapped holes in soft woods such as pine tend to strip, but using a rivet nut threaded insert can repair a stripped hole or create an anchor for a firm joint. Stud inserts, such as those used in making furniture, are also used to create a secure threaded stud that can accept a nut.

Thick-wall inserts are often used with metal, though slotted body inserts are typically used for thin sheets of metal. For softer metals such as aluminum, aluminum inserts and slotted body inserts are frequently used.

Rivet nut threaded inserts are used in concrete for construction applications. You will usually find thick-walled inserts and stud-style inserts used in concrete foundations and structures.

These are some of the different types of threaded inserts available, and this information can help you choose the best threaded inserts for your specific application. You can find inserts for jobs of any size and holes of any diameter. Additionally, there are materials for special applications, such as brass and aluminum that won’t corrode, or non-conductive inserts for electronic applications

Preguntas frecuentes

Coil thread inserts are an ingenious solution to a common engineering problem—how to insert a threaded fastener into a stripped bolt hole or soft material. What is the difference between a coil thread insert and a Heli-Coil? Actually, there is no difference.

Threaded inserts are commonly used in plastic casings, housing, and parts to create a metal thread (typically: brass or stainless steel) to allow for screws to be used in the assembly of many consumer electronics and consumer products.

A threaded insert is a sleeve with a threaded interior that can accept a bolt or threaded fastener. The insert can have different dimensions, be made of different materials, and come in different configurations or tooling; its design will hold fast in thin or soft materials, making the threaded fastener secure

Threaded inserts provide permanent machine screw threads in wood, plastic, soft metal, or other porous materials. Threaded inserts are often used to replace worn wood screw or metal screw holes that have become oversized due to wear.

Use thread-in inserts in softer woods and plywood where their coarse outside threads cut easily into the surrounding wood. Simply drill a hole sized for the body of the insert, and screw it into place.

They offer a stronger alternative to weld nuts and tapped holes, and they provide a stronger bond than self-tapping screws. In fact, threaded inserts are usually the strongest and least time-consuming fasteners used in any manufacturing setting, especially because they were designed for automation
