Engineering and ordering notes

Table dimensions are in inches and apply before coating. The word “lock” is the historical product-family name and does not guarantee permanent locking of a bolted joint. Confirm the required material grade, finish specification, coating thickness, joint preload, vibration conditions, and service environment before ordering. For electroplated carbon-steel washers, hydrogen-embrittlement relief and the required post-plating test must be specified and verified. The displayed mass is a theoretical estimate based on the tabulated section geometry; final manufactured mass may vary within dimensional and coating tolerances.
