Abstract
Abstract The torque of fasteners, such as bolts, nuts and the like, is stabilized by a torque stabilizing agent comprising an organic film forming material and about 2% to about 25% by weight of a surface active agent. Applying the torque stabilizing agent to a fastener prevents defect of the fastening part, such as disconnection or damage.

A torque stabilizing agent for maintaining the coefficient of friction of threaded a metal or metal alloy fastener within the range of about 0.1 to about 0.2 comprising a film-forming water emulsifying alkyd resin and from about 2% to about 25% by weight of a polyoxyalkylene monoalkyl ether fatty acid ester surface active agent.
Claim 2
Dependent Claim
54 words
A torque stabilizing agent for maintaining the coefficient of friction of threaded a metal or metal alloy fastener within the range of about 0.1 to about 0.2 comprising a film-forming water emulsifying alkyd resin and from about 2% to about 25% by weight of a polyoxyalkylene monoalkyl ether fatty acid ester surface active agent.
Claim 3
Independent Claim
73 words
A method of stabilizing the torque of threaded a metal or metal alloy fastener comprising applying to the fastener a torque stabilizing agent comprising a film-forming water emulsifying alkyd resin and from about 2 to about 25% by weight of a polyoxyalkylene monoalkyl ether fatty acid ester, said torque stabilizing agent maintaining the coefficient of friction of said fastener within the range of about 0.1 to about 0.2, and drying the thus-treated fastener.
Claim 4
Independent Claim
73 words
A method of stabilizing the torque of threaded a metal or metal alloy fastener comprising applying to the fastener a torque stabilizing agent comprising a film-forming water emulsifying alkyd resin and from about 2 to about 25% by weight of a polyoxyalkylene monoalkyl ether fatty acid ester, said torque stabilizing agent maintaining the coefficient of friction of said fastener within the range of about 0.1 to about 0.2, and drying the thus-treated fastener.
