- Description
- This blue and black lenticular card has a ruler along the top edge. When viewed at one angle, a centimeter ruler is divided to millimeters and numbered by ones from 1 to 15. Below the ruler is a table for rivet code numbers, with row headings POP TAP, POP TLP, and IMEX. From another angle, a six-inch ruler is divided to 1/32" and numbered by ones from 1 to 6. Below the ruler is a table for riveting thickness, with row headings POP ALUM, POP MONEL, and IMEX.
- British engineer Hamilton Neil Wylie invented blind or pop rivets between 1916 and 1927. They may be installed in situations where the body (such as an aircraft) or building being assembled may be accessed from only one side. Introduced in 1955, Imex rivets are sealed on one side. While both terms are now in common use, Pop and Imex were originally brand names used by the George Tucker Eyelet Company of Birmingham, England. The rivet metals in the table include aluminum and Monel, a nickel alloy trademarked by Special Metals Corporation of New Hartford, N.Y.
