The Bollhoff PLUSNUT® provides the ultimate pull out strength in thin sheet metals and soft plastics. It features a slotted body that splits into four legs during installation, which helps provide a wide load-bearing surface on the backside of the parent material. This splitting is why they are sometimes referred to as split rivet nuts.

Rivet Nut USA (an operating division of Cardinal Components, Inc.) is a Preferred Authorized Bollhoff Distributor of the Bollhoff PLUSNUT®. Bollhoff PLUSNUT® fasteners are the original trademarked version of “slotted body rivet nuts”. To provide our customers the best availability and variety, we also offer non-Bollhoff slotted body rivet nuts & fasteners. We’re the largest in-stock specialty fastener distributor in the USA.

The PLUSNUT® features the widest material grip range of all blind threaded fasteners (nearly a quarter of an inch!) A wide material grip range is helpful when your application may have variable material thicknesses, such as thermoformed, rotational or blow molded plastics. Sprinter or work van enthusiasts prefer the PLUSNUT® as their go-to internally threaded slotted body rivet nut fastener solution.

Rivet Nut USA stocks a selection of installation tools for easy-to-use and reliable PLUSNUT® installation such as our pneumatic nut insert tools (4090P & 6703P), manual hand tools (C1000, C7000 & 140-2000). Check out our “Install Tools” page for more information.

The Pre-Bulbed PLUSNUT® is a version that offers very low installation load force. This version is ideal for consumer-centric applications, such as outfitting a pick-up truck or boat with an aftermarket accessory. Package the Pre-Bulbed PLUSNUT® fasteners with the C1000 tool to create a kit that each of your customers can use!

PLUSNUT® (aka ‘Plus Body’) (aka ‘Slotted Body’)

Rivet Nut USA carries Bollhoff PLUSNUT® Blind Fasteners for the the most rigid fastening. A PLUSNUT® is a blind, threaded insert recommended for rigid fastening in sheet metal, fiberglass and plastics. The slotted shank spreads and forms large flaps to evenly distribute working loads over a large area. Bollhoff PLUSNUT® fasteners are ideal when you cannot access one side, or if it is very difficult to do so. The PLUSNUT® is easy to use and yet maintains the strength and integrity needed for industrial or heavy duty applications.

Bollhoff PLUSNUT® fasteners provide incredible pull-out strength, as well as grip. Where strength is the main goal, this is an ideal fastener to use. PLUSNUTS® are also ideal for a variety of applications, as both soft or brittle materials accept this fastener optimally, and without damage to the softer materials; which is why PLUSNUTS® are considered the rivet nut for plastic!

Our PLUSNUTS® are quality parts, manufactured by Bollhoff, a leader in the industry. We are ISO 9001 certified, so our PLUSNUT® production and customer service are of the highest quality. If you need blind Bollhoff PLUSNUTS®, remember Cardinal Components. We supply high quality PLUSNUTS® at competitive prices and our in-stock items ship the same day they are ordered. Check out our wide variety or call us to discuss your PLUSNUT® fastener needs today!
