SELF-CLINCHING NUTS AND STUDS FOR HARD SHEET MATERIALS

1 min read

A newly developed range of self-clinching nuts and studs, introduced for permanent installation into especially hard sheet materials, deliver design and assembly benefits for automotive component attachment applications, says manufacturer PennEngineering.

SH hard panel nuts and HFLH hard panel studs are manufactured from hardened alloy steel to provide stronger thread strength. They further enable close-to-edge mounting without risking panel buckling, allow for cost-effective component standardization, and resolve environmental and recycling concerns typically associated with alternative thin-sheet fastening devices. In addition, these fasteners can promote lower installed cost by eliminating any need for embossing operations, reducing the amount of required hardware in an assembly, and installing automatically using a standard press or in-die technology. Type SH hard panel nuts feature a small outer diameter and lightweight design. They can install reliably into high-strength steel sheets up to 975MPa and in panels as hard as HRC 30 / HB 277 or less on the Rockwell C and Brinell scales, respectively. Host panels can be as thin as 1.4mm and, once installed, the reverse side of the panel remains flush to enhance cosmetics. Nut thread sizes range from M6 to M10 with Imperial equivalents. Type HFLH hard panel studs can install into high-strength steel sheets up to 700MPa and in panels as hard as HRB 96 / HB 216 or less on the Rockwell B and Brinell scales, respectively. Host panels can be as thin as 1mm and stud thread sizes range from M5 to M8. Detailed specifications, Cad models, and performance data for these RoHS-compliant fasteners can be accessed online.
