Product Description Where separate panels are to be securely mated, these U Type fasteners provide the same rapid attachment and ease of assembly inherent in all spring nut designs. They are easy to remove yet grip with a positive holding power that stays until you want it to loosen.
Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.
