Key Features of Mechanically Operated Rubber Filled Hydraulic Nuts

• This is a mechanically operated, shim type nut.
• It is activated by tightening socket head cap screws located in the top of the nut.
• The nut has a flanged piston.
• A shim gap is created between the body and the piston when the nut is operated.
• The size of the shim gap is a combination of the compression of the bolted joint and gasket, if fitted, plus the elongation of the bolt.
• In use the socket head cap screws are tightened until the shim gap is large enough to accept the pre machined shims.
• The socket head cap screws are then removed and the pre load is transferred onto the shims.
• A very high percentage of the load is retained in the bolt. The mechanical operating system is unloaded during service
