FLOATING SELF-CLINCHING FASTENERS FOR STAINLESS COMPENSATE FOR MATING HOLE MISALIGNMENT

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 non-locking or locking threads and will permit up to .030 in/0.76 mm total adjustment for mating hole misalignment. Non-locking Type A4 and self-locking Type LA4 fasteners provide load-bearing threads in stainless sheets as thin as .038 in/0.97 mm and greater with hardness of HRB 88 on the Rockwell "B" scale. Available thread sizes range from #4-40 through #10-32 and M3 through 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 pushout 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 can be accessed at www.pemnet.com.
