ATLAS® SpinTite® blind threaded inserts 19 November 2018

ATLAS® SpinTite® blind threaded inserts from PennEngineering® provide strong, permanent, and reusable threads in thin sheet materials where only one side is accessible for hardware installation.

Installation is performed from the accessible ‘front’ side using spin-spin tooling technology. The inserts then become permanently mounted on the ‘back’ side to accept a mating screw for final component attachment. The ‘blind’ installation capability especially suits applications such as tubing, extrusions, and others where access to the back side is either limited or non-existent.

These steel, aluminium, brass or stainless steel inserts ideally replace tapped holes, weld nuts, rivets, self-drilling or tapping screws, and through-bolted applications necessitating loose hardware. They support close-to-edge applications and can be installed at any stage during the production process (even after assemblies have been painted). In service, the inserts exhibit high thread strength and high torque-out resistance.

ATLAS SpinTite inserts have been designed for use with panels or sheets of any hardness or material (including metal, plastics and fiberglass) as thin as 0.020 inches/0.51mm. They additionally can assemble multiple dissimilar materials during installation, eliminating any need to perform spot welding or other secondary operations, saving time and money during production.

This family of inserts includes half-hex shank low profile head, rib wall minimised profile head, rib wall low profile head, thin wall low profile head, and swaging low profile head versions. A variety of available thread sizes range from #6-32 to ½ inch – 13 inch and M4 to M12, depending on insert type. Custom inserts can also be engineered to satisfy specific application performance requirements.

Detailed specifications, fastener drawings and 3D models, and performance data (ATLAS Catalog) for these RoHS compliant inserts can be viewed and downloaded from PennEngineering’s website.
