The RivetKing NHL and NHR Series are heavywall European style rivetnuts. This robust design upgrades the thickness of both the body and the head height which provides higher pullout resistance and increased endurance of the joint and assembly. The NHL series has a large head, whearas the NHR series had a reduced head and they both have a full hex shaped body which resist spin out.
The RivetKing IHF Series is a thinwall half hex insert for use in hexagonal holes. The half hex thinwall rivetnut is designed for use with spin-spin tools. The torque to set is far less than the full hex heavy wall inserts. The low profile head is wide and thin and allows for a newar flush installation.
The RivetKing IKF Series is a thinwall Rivetnut with a low profile head and the IKR Series has a reduced head. The design is such that spin/spin tools can easily collapse and properly set the rivet nut. The low profile head is nearly flush and offers greater bearing surface compared with the IKR series, whereas the IKR series provides for a completely flush installation in the sheet metal.
The RivetKing IPB and IPN Series Rivetnuts do what traditional rivet nuts cannot. This series is designed for soft materials such as plastics, fiberglass and thin sheet metal where increased pullout resistance is required. The fastener performance is dictated by the four folding tines that are extended during the riveting process. The result is an upset of metal that is nearly three times the diameter of the hole. This series is offered in both pre-bulbed and straight shank versions. The pre-bulbed version is designed to work with spin-spin tools, while the straight shank version is designed to work with spin-pull tools only.
The RivetKing IRL Series is a heavywall/thickwall Rivetnut. This robust design upgrades the thickness of both the body and the head height. The robust IRL series offers higher pullout resistance and increased endurance of the joint and assembly. The RivetKing IRR Series is a thinwall inser that has been designed specifically for convenience. Often the holes of harware are pre-drilled or pre-punched to a standard hole size. This may cause difficulties with traditional rivetnuts which require an off-standard hole diameter. The IRR series have been produced to fit in common hole sizes that may be found in pre-designed hardware and assemblies.
The RivetKing ISN/ISR Series has the grip range that most rivetnuts lack. It has an unlimited maximum grip range which will work in all thickness above .030 (ISR Series) and .062 (ISN Series). The ISR series is designed for use in any metal, while the ISN series is designed for se in any material softer than itself such as plastics, fiberglass, and plywood.
