MATERIALS: PennEngineering’s PEM® large-sized self-clinching studs come in lengths up to 6 inch/152 mm and thread sizes up to ½ inch/M14 to offer a value-added capability that allows users to select from a wide range of variations to tailor fastener to application needs. Among available variations, studs can be ordered in assorted head and clinch styles, including six-lobe, multi-lug, knurl and hexagonal; they can be specially heat-treated to achieve greater tensile strength (up to Grade 10.9); dog point threads will enable quick location of the mating fastener; MAThread®/MATpoint® anti cross-threading design will allow for threads to self-align to prevent jamming, correct off-angle installations and speed production; and all types can be supplied in a range of finishes and coatings. The studs install easily (without welding) using any parallel acting press or automated equipment and embed securely and permanently in metal sheets or sections as thin as .036 inch/.91 mm with hardness up to HRB 85/HB 165. They can reliably attach components or assemblies in the agricultural, automotive and railroad, construction, electrical, HVAC, and material handling industries, among others.
