A new four-page product bulletin available from PennEngineering Fastening Technologies profiles PEM self-locating projection weld nuts.
A new four-page product bulletin available from PennEngineering Fastening Technologies profiles PEM self-locating projection weld nuts.
These fasteners provide load-bearing threads in metal sheets too thin to tap and incorporate unique engineering to help promote cost-effective and efficient component assembly.
"Bulletin WN" covers fastener specifications, installation procedure, and performance data.
A special section features a "Guide to better welding".
PEM weld nuts offer a variety of design advantages compared with other traditional weld nuts to help speed production.
Self-locating shanks properly position the nuts without the need for pilots or complicated electrodes and further serve to protect threads from weld splatter, making time-consuming splatter-removal operations unnecessary.
Engineered projections prevent burnouts in thin sheets.
A round head eliminates any need for tedious, time-consuming indexing.
PEM weld nuts are available in steel (Type WN) and stainless steel (Type WNS) in thread sizes ranging from 4-40 through 1/4-20 and M3 to M6.
Their compact profile enables them to fit on narrow flanges.
Stainless types offer the added benefits of corrosion-resistance and non-magnetic properties.
All types can be installed easily and permanently in steel or stainless sheets as thin as 0.8mm.
"Bulletin WN" can be downloaded free in PDF format from the PennEngineering Fastening Technologies website.
