Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally accepted
as a safe working load. Reference should be made to applicable codes for specific working ratio. Critical applications, vibratory, shock loads, overhead
installations, etc. may require a safety factor of as much as 10:1, or more.
