The most corrosion resistant twist-resistant rivet nuts we offer, these stand up to chemicals. A ribbed body holds the nut in place so it won't turn when tightening a screw. Also known as blind inserts, they can be installed when you have access to only one side of the material. Install in a drilled hole using a rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Stainless Steel Low-Profile Rivet Nuts
![](/prerenderstable/mvPRE/contents/gfx/imagecache/980/98005a140p1-b01-digitall@halfx_636713278606970000.png?ver=imagenotfound)
The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals. They're often used for light duty fastening in low-clearance applications. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut. The tin-plating provides lubricity allowing the nut to collapse smoothly. Drill bit size listed in the table is for material with a 0.030"-0.090" thickness. These rivet nuts can be installed in thicker material, but may require larger holes. Install them using a hand- or power-driven rivet nut tool. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped. For a strong grip, these nuts have distorted threads that increase friction with bolts. Because they mount with two rivets, they won’t spin when you’re tightening screws. However, these nuts do move inside their retainers, which lets you install bolts at a slight angle; use them to align with off-center parts. All meet military guidelines for dimensions and material.
A286 stainless steel nuts are corrosion resistant. Silver-plated stainless steel nuts withstand temperatures up to 800° F. The silver plating also adds lubricity and prevents seizing caused by friction between nuts and bolts.
Lubricated nuts thread onto bolts smoothly.
