Socket button barrel nuts (button head sleeve nuts) host a hexagonal recess in the head. These socket button head barrel nuts are installed using a hex wrench or insert bit.
This, together with the relatively large head diameter, provides higher resistance to cam-out and they can be used with power drivers enabling faster installation and higher torque to be achieved.
These barrel nuts are available from Fastenright in Zinc plated Steel, with other materials and finishes available to order.
Available sizes range from M5 to M10. We also provide a large range of imperial diameter socket button barrel nuts in various materials.
Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
