Description

The Rivscrew® PL rivet is installed using a hexagonal shaped mandrel. During installation, the mandrel expands the rivet body radially adjacent to the six corners of the hexagonal shape. This forces the threads on the rivet body into the application forming a thread in the material. Thread forming in this manner a provides higher vibration resistant "thread lock" in the parent material compared to standard screws, while eliminating the need for costly tapping or thread-forming operations. Additionally, the hexagonal mandrel head is designed to the size of a standard Allen wrench so as the mandrel moves through the rivet, it creates that same shape on the inner wall and head of the rivet. This allows the Rivscrew® rivet to be removed and re-applied, making it ideal for applications requiring disassembly for repair or rework. They can simply be unscrewed using a standard hexagonal Allen key.

While the Rivscrew® PL rivet is flexible in many ways, proper installation and performance can only be attained when the application parameters meet the specified ranges. Please consult the technical specifications when applying the Rivscrew® PL rivet.

Speed fasteners are placed using a unique repetition mandrel system. Rivets are loaded into specialist tooling and, during placement, the tool pulls the mandrel through the rivet giving both axial and radial expansion (providing clamp and hole fill). At the end of each cycle the next rivet is automatically delivered to the nose piece ready for placement. For large volume applications the fasteners can be bowl fed using automated equipment which gives continuous feed with cycle times as low as 1.5 seconds.

Features

• One-sided installation. Eases assembly.
• Designed on the principle of placement by expansion. High pull-out resistance and no risk of stripping and debris during placing.
• Use in a wide range of thermoplastics. Increased number of applications and rationalization of part numbers.
• No torque control to be applied. No risks of thread strip-out during installation.
• Vibration resistant.
• Flexible. Accommodates variations in material thickness. No resetting for different joints.
• Wide grip range. Enables the replacement of several different screws.
• Quick installation with standard equipment. Reduced production and maintenance costs.
• Wide choice of installation systems. Increased productivity, efficient introduction into the production process and lower in-place costs.

• Plastics with a flexural modulus between 340,000 and 1,400,000 p.s.i. (2000 to 10000 N/mm2)
