The washer’s inner tab fits into a keyway on the shaft, and one of the outer tabs is then bent into a slot on the nut to secure it. What is the standard tightening procedure for a KM series lock nut? Tightening should be done using a suitable hook spanner (e.g., DIN 1810). The nut should be tightened to remove clearance, then slightly loosened before being secured to the specified torque or angle to achieve the correct bearing preload. Always consult the machine’s maintenance manual for specific values. Is the H.GP marking on the nut significant for its application? The ‘H.GP’ marking typically indicates manufacturing details such as the production plant or a specific material treatment process. For standard applications, it does not affect the form, fit, or function, which are defined by the ‘KM17’ designation according to DIN 981. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
