Threaded Inserts

STANLEY Engineered Fastening offers a variety of threaded insert options including threaded inserts, screw thread coils, blind rivets, blind rivet nuts, bolts, specialized threaded inserts, and internal thread locking systems.

Screw Thread Inserts

Heli-Coil® inserts are precision-formed screw thread coils of stainless steel wire with a diamond-shaped cross section. They are also available in several kinds of titanium alloys, preferred by the world’s premier space and satellite companies. Heli-Coil wire thread inserts comply with AS9100C aerospace standards, OEM Designs and other custom requirements often needed for severe environments. Heli-Coil products are used with confidence in the aerospace, electronics, automotive, telecommunications, and defense industries, where quality and performance is a must.

Threaded Inserts

Dodge® offers a full line of threaded inserts for plastics including brass inserts to suit almost any insert application in plastic. Inserts can be installed using virtually all methods of installation.

The WELL-NUT® threaded insert is a flanged chloroprene bushing with a brass machine nut molded into one end. Tightening a conventional machine screw threaded in the brass nut causes the insert to expand, creating a secure fastening.

The JACK NUT® threaded insert is an economical blind fastener designed for assembly line use in thin, soft, or brittle materials. When tightened, the body collapses to form four legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert.

Other Threaded Inserts (available in brass, stainless steel and low carbon steel) are ideal for plastics, alloys and composite materials. They are designed to provide strong metal threads for machine screws.

Internal Thread Locking Systems

Spiralock® is a unique and proprietary preload locking internal (female) thread form that's exceptionally resistant to transverse vibration—the primary cause of thread loosening. It's ideal for a wide variety of applications, especially in aerospace and electronics.

Blind Nuts (or Blind Threaded Inserts)

Wherever you need high quality, load bearing threads in thin materials, Avdel® and POP® have a broad range of high performance blind threaded inserts in various materials, forms and sizes. Blind Threaded Inserts are multi-functional fasteners: they povide a female thread while giving the opportunity to clamp two or more sheets at the same time, and can also act as a spacer.
