Female Threaded Round Standoffs
Use standoffs to position components in assemblies, as well as to separate or connect parts.
18-8 stainless steel standoffs have good corrosion resistance and may be mildly magnetic.
Zinc-plated steel standoffs provide some corrosion resistance.
Aluminum standoffs are lightweight, nonmagnetic, and mildly corrosion resistant. Material can vary between 6061 and 2011 aluminum.
Zinc-plated brass standoffs are electrically conductive, nonmagnetic, and have a corrosion-resistant finish.
Nylon standoffs have excellent wear and abrasion resistance and also offer resistance to chemicals and solvents (except mineral acids). Exposure to moisture may cause them to expand.

18-8 stainless steel standoffs have good corrosion resistance and may be mildly magnetic.
Zinc-plated steel standoffs provide some corrosion resistance.
Aluminum standoffs are lightweight, nonmagnetic, and mildly corrosion resistant. Material can vary between 6061 and 2011 aluminum.

Miniature Press-Fit Threaded Standoffs with Open End
Designed to fit in the limited space of compact electronics, such as laptops and hand-held devices, these standoffs have a recess under the head that clinches a panel while splines on the head bite in for an extra-stong hold. The open end creates a through hole. Standoffs have excellent wear resistance and may be mildly magnetic. Use a lever press to install.

Stainless Steel Helical Inserts without Prong
Without a prong to break off and retrieve, these inserts are often used where debris could cause damage. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. Installation requires a drill bit, a helical insert tap, and an installation tool.
Add an extraction tool to remove these inserts.

Brass Screw-to-Expand Inserts for Plastic
Made from brass, these inserts are electrically conductive, nonmagnetic, and have good corrosion resistance. Press them into a drilled hole, then install a screw to expand the insert and drive the knurls into the surrounding plastic to keep it secure.

Tapered Heat-Set Inserts for Plastic
The tapered shape makes it easier to guide these inserts into a hole during installation. Use a drill bit to create a straight hole, then taper the top half. Heat inserts with a soldering tip so that they melt the plastic when installed. As the plastic cools, it solidifies around the knurls and ridges on the insert for excellent resistance to both torque and pull-out.
Made with lead, brass inserts are stronger than aluminum and other brass alloys but not as strong as 303 stainless steel inserts. They have good corrosion resistance.
303 stainless steel inserts are stronger than brass and aluminum inserts, have excellent corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.
Inserts that meet ASTM standards comply with specifications for material quality.
