Round Body Rivet Nuts
Sherex by PEM offers a comprehensive selection of round body rivet nuts designed to fit into Inch (Imperial) or Metric drilled or punched hole sizes.


Blind Rivet Nuts provide load-bearing threads in thin sheet materials that are too thin for a tapped thread. They are called “blind” because they can be installed from one side of the workpiece. Once the rivet nut is installed, additional components can be attached using threaded fasteners.
NEW in 2024: Sherex by PEM now provides ATLAS® rivet nuts in its catalog! ATLAS® rivet nuts by PennEngineering®include its popular SpinTite®, MaxTite®, and Plus+Tite® line of rivet nuts. These products and more are now available through Sherex by PEM!

Sherex by PEM's Optisert is a new round-body rivet nut that features a knurled-body and underhead wedge design that gives the rivet nut superior strength.

Hex Body Rivet Nuts
Hex body rivet nuts provide superior spin-out resistance to round body rivet nuts. When a hex-shaped hole can be produced, we recommend using one of our half hex or full hex rivet nut product lines:
- Half Hex rivet nuts are ideal for light-duty applications and can be installed using all Sherex by PEM tools
- Full Hex rivet nuts are ideal for heavy-duty applications and should be installed with hydro-pneumatic spin-pull tools

Large Size Rivet Nuts
Sherex by PEM Large Size rivet nuts are offered in sizes from 3/4 -10 and M16. These rivet nuts were developed for applications where critical joint performance and high tensile loads are required., such as automotive, heavy truck/trailer, ag/construction equipment, pole/tower, HVAC, and other applications requiring larger sized bolts in thin materials.
Features & Benefits:
- Provide a Strong Thread in Thin Sheet Materials
- Can be Installed from One Side of the Work Piece
- Do Not Need to be Welded to the Base Material
- Available in a Round Body or a Full Hex Body For Increased Spin Out Resistance
- Plated with a RoHS Complaint Zinc Trivalent Clear Plating
- Installed with FLEX-18 Hydro-Pneumatic Rivet Nut Tool
High Strength Rivet Nuts
Sherex by PEM's new High Strength Rivet Nuts are designed to meet the rigorous demands of high-clamp-load environments. Available as a standard catalog product in hex body and round body, open end and closed designs, these rivet nuts deliver exceptional performance when paired with Class 10.9 (metric) or Grade 8 (imperial) bolts. Ideal for industries like automotive, heavy truck, construction, and agriculture equipment, they provide a reliable, high-strength alternative to traditional weld nuts—offering high strength thresholds without the complexities of welding.
Made from high strength steel for superior durability and tensile strength, Sherex by PEM High Strength Rivet Nuts ensure secure, vibration-resistant joints in applications where failure is not an option. Sizes range from M5 to M12, with unified equivalents available, making them versatile for a wide array of projects. Installation is straightforward using standard rivet nut tooling, allowing for quick integration into your assembly processes without specialized equipment.
Key Benefits:
- Superior Strength: Supports high-torque applications, rated for Class 10/Grade 8 thread proof load
- Versatile Designs: Hex body and round body allow for design ambiguity
- Efficiency Gains: Eliminate welding hazards, reduce labor costs, and streamline production
- Broad Compatibility: Suitable for thin-sheet materials in heavy-duty sectors, ensuring long-term reliability under extreme loads.

RIV-FLOAT® rivet nuts feature an internally floating thread, allowing for component attachments in off-center applications. This innovative, patented rivet nut helps assemblers easily handle tolerance stack up in joint design and misalignment during service of the joint.
RIV-FLOAT® also allows post-finish installation in applications where weld nuts or cage nuts are typically used.
RIV-FLOAT® Short's low-profile design, it provides greater backside clearance making it ideal for space-constrained applications. With 0.020” radial float, it delivers both flexibility and helps eliminates cross-threading during assembly.
Install both RIV-FLOAT and RIV-FLOAT Short with standard rivet nut hydro-pneumatic tooling.
This is part of Sherex by PEM's best practice fasteners for blind rivet nuts.
See the 3D model video for an installation example.
