Fasteners provide load-bearing threads

A Penn Engineering product story
Edited by the Engineeringtalk editorial team Mar 31, 2008

Floating self-clinching fasteners are designed for permanent installation in thin stainless-steel sheets.

A new family of PEM floating self-clinching fasteners has been introduced for permanent installation into thin stainless steel sheets.

The fasteners can be specified either with nonlocking or locking threads and will permit up to 0.76mm total adjustment for mating hole misalignment.

Nonlocking Type A4 and self-locking Type LA4 fasteners provide load-bearing threads in stainless sheets as thin as 0.97mm and greater with hardness of HRB 88 on the Rockwell B scale.

Thread sizes range from 4-40 to 10-32 and M3 to M5.

Installation is quick and simple.

The fasteners are squeezed into properly sized holes using a Pemserter press or other standard equipment.

All clinching occurs on the fastener side of the sheet, which allows the sheet to remain flush on one side.

The fastener is permanently locked in place, exhibits high torque-out and push-out resistance, and becomes an integral part of the stainless assembly.

Mating hardware completes final component attachment.

Detailed specifications (Bulletin A4) and free part drawings (PEM CAD Library) for these RoHS-compliant fasteners are available on the PennEngineering website.
