What do the terms Light Duty, Standard (Medium) Duty, & Heavy Duty mean?

These terms describe the three most common duty classifications of coiled pins. Coiled style pins expand the parameters of spring pin usage. The advantages of coiled pins are enhanced by the variety of styles within the coiled pin family. Light, Standard, and Heavy are the foundation on which other coiled pins are built. As their names imply, each duty is more appropriate for some situations than for others. Users should refer to the MINIMUM DOUBLE SHEAR LOAD rating for relative strength of mechanical performance for each duty classification. Light Duty offers the least double shear value and is appropriate in soft and malleable materials and where loading isn’t much of a issue. The terms Standard and Medium are used interchangeably. Standard duty pins offer excellent double shear values and can be used in a wide variety of applications. Heavy duty pins have the greatest double shear values and can be considered for applications where shear and shock loads are high.
