Self-Clinching Studs Introduced in Longer Lengths, Larger Thread Sizes

Friday, January 01, 2010

PennEngineering, Danboro, PA, has introduced a new family of its PEM large-sized self-clinching studs, ideal for applications requiring high fastener torque-out and pushout. The clinch studs—in lengths to 6 in. and thread sizes to ½ in. (M14)—are of carbon or alloy steel. They feature large-diameter and strong heads to minimize compressive stress on panels and develop full thread strength in service.

The studs can be ordered in assorted head and clinch styles, including six-lobe, multi-lug, knurl and hexagonal. They can be specially heattreated to achieve greater tensile strength (up to grade 10.9). Dog point threads will enable quick location of the mating fastener, and their anticross-threading design allows for threads to self-align to prevent jamming, correct off-angle installations and speed production.

The studs install easily without the need for welding, using any parallel-acting press or automated equipment, and will embed securely and permanently in sheetmetal or sections as thin as 0.036 in.
