TIGHTENED BODY TIGHTENING FORCE STABILIZATION AGENT, METHOD FOR STABILIZATION OF TIGHTENING FORCE USING THE STABILIZATION AGENT, AND TIGHTENED BODY COMPONENT PART COATED WITH STABILIZATION AGENT

摘要

A tightened body tightening force stabilization agent capable of minimizing a variation in torque coefficient suitable for controlling a tightened body tightening force by a torque method, comprising, as an active ingredient, a polymer of unsaturated chain hydrocarbon with a carbon quantity of four; a method for stabilization of tightened body tightening force, comprising the steps of applying the polymer to at least either of a thread part such as a bolt member and a washer and the threaded part or seat surface of the tightened body and performing a tightening operation.
