Self-clinching studs have large diameter heads

09 May 2012

PEM self-clinching studs with large-diameter heads distribute axial tightening force over a large area. The result is improved pull through performance, reduced compressive stress on the panel, and development of full thread strength.  All four types of these RoHS-compliant studs offer cost-effective alternatives to weld studs by enabling easier installation with fewer production steps.

Type HFE steel studs install permanently in steel or aluminum sheets as thin as 1mm with hardness of HRB 85 (or less) and HB 165 (or less). Thread sizes range from #10-32 through 5/16-18 and M5 through M8. Standard stud lengths are available up to 50mm.

Type HFH steel studs for high-strength applications meet Grade 5/Property Class 9.8 tensile requirements and install permanently in steel or aluminum sheets as thin as 1.3mm with hardness of HRB 85 (or less) and HB 165 (or less). Thread sizes range from #10-32 through 3/8-16 and M5 through M10. Standard stud lengths can be supplied up to 50mm.

Types HFG8 (unified) and HF109 (metric) high tensile strength studs provide solutions for the most demanding applications.  These carbon alloy steel studs are specially heat-treated to achieve greater hardness and tensile strength up to Grade 8/Property Class 10.9 meeting 1040 MPa minimum. They install permanently in steel or HSLA steel sheets as thin as 1mm with hardness of HRB 89 (or less) and HB 180 (or less). Thread sizes for Type HFG8 studs range from #10-32 through 5/16-18 and from M5 through M8 for HF109 versions.  Standard stud lengths can be ordered up to 25mm.
