Add to my favorite
New microPEM® TackSert™ (Type TK™) pins are designed with a diagonal knurl to hold a top panel to a bottom panel or chassis by broaching into the bottom panel/chassis. Type TKA (aluminum) pins are suitable for broaching into plastic applications, and Type TK4 (400 series stainless steel) pins are suitable for broaching into castings and brittle materials.
