These pins feature hollow cylinders slit longitudinally permitting compression during insertion. Designed to replace Taper pins, straight pins, and set screws, they will also serve as a rivet, dowel, hinge pin or cotter pin in many applications. Made of 1070 carbon spring steel hardened to Rockwell 45-50, tempered and oiled, They can be doubled up for heavy duty applications (See Chart). Plain or plated finishes available as well as stainless steel. Stocked in lengths to fit holes from .062" to .510".
