2) Our rivets begin peeling from the extreme end of the rivet, which provides the extra long grip range, up to 9/16″ thickness. Here are the key performance enhancements our Exploding Peel Rivets provide: 1) Powerful 1,000 pounds of clamping force to hold your application securely in place. The customer feedback identified the top three advantages our exploding peel rivets have over other brands. When installed, the back or blind side of these rivets “explodes” into four pedals and pulls application layers tightly together while it peels and clamps. All specified finishes are tested by RivetKing in accordance with ASTM B117 standards.Exploding Peel Rivets get their name from the positive customer feedback and their descriptions of how well our rivets perform. Other platings such as zinc alloys (Zinc Nickel, Zinc Iron, Tin Zinc) are available which can extend the SST rating to 840 hours until red rust. For standard performance, an SST rating of 24 hours until red rust is common. Because blind rivets are plated before they are assembled, do not attempt to post-plate an assembled rivet. Being that the most cost effective material to manufacture is steel, most prefer to protect the steel with a plating such as Zinc Chromate, or other alloy platings. Corrosion Protection: The corrosion factor of a particular rivet is dependent on the corrosivities of the base metal, the protective layer (plating) and the conversion layer (chromate). Testing should be done in the design phase to calculate what distances are needed and to verify proper functionality. Therefore, be sure the secondary side can accommodate the entire rivet length (including the mandrel head), before riveting. Keep in mind, the collapsed height is shorter than the pre-installed height. Blind Side Clearance: Since the blind side of the rivet is designed to form into a secondary flange, it is important to leave room for the flange to expand and seat properly. This is especially critical when riveting on brackets and other hardware next to bends, folds, extrusions and/or cutouts on the applications. When designing the primary hole, be sure to calculate the head diameter and its tolerances as well as the layout footprint of the head around the hole. Head Clearance: Axial access is required on the primary side being riveted to allow for the flange to overlap the hole without interference. Be sure to account for the riveting equipment in the design phase to prevent the need for customized and potentially costly tooling modifications. Tool Clearance: Sufficient clearances are needed so that the tool can access the joint being riveted without interference. Be sure to verify the compatibility of the rivet materials as galvanic corrosion can occur and is seldom considered in the design phase. As a general rule, a rivet should be used in materials equal to or greater than its own strength, although custom rivets can be produced to work in softer materials. Whenever possible, the stronger material should be the secondary side because this is where the setting will take place. Joint Materials & Strength: It is sometimes necessary to use dissimilar materials such as fastening aluminum to steel or plastics to aluminum. Additionally, the design engineer should calculate the manufacturing tolerances of the hole to ensure proper fit so that interference issues will not occur later. A rivet is only guaranteed to function as designed when the hole size is within the prescribed range. We specify a hole size for every rivet we manufacture. Hole Size: Hole sizes are extremely important for the proper functionality of blind rivets. While the grip may be calculated by adding the thickness of the two materials together, be sure to account for any burrs, bends and manufacturing tolerances which may increase or decrease the overall grip of the materials being riveted. Also be sure to account for the theoretical grip versus the actual grip. Failure to adhere to the grip range may also cause a premature break or difficulty in clearing the spent mandrel from the setting tool. Rivets set under-grip can bend and offset, reducing the overall strength and aesthetic appearance. Rivets set over-grip will not retain the mandrel head, causing it to fall out of the rivet body after setting. Setting rivets outside of their specified grip range can lead to functional failures. This thickness is commonly called the grip range. All manufacturers list a range of material thickness in which the product will perform properly. If the rivet is applied over or under its intended grip range, it may not work properly. Grip Range: Determining the length of the rivet is critical to ensure the rivet will function as intended.
