How To Unscrew The Stainless Steel Expansion Bolt If It Rusts?

In daily life, when stainless steel expansion bolts rust, unscrewing them may become a hassle. However, there are several techniques that can help you easily deal with this problem.

Stainless steel expansion bolts: Introduction to fixation principle
Stainless steel expansion bolts are fixed using the principle of wedge-shaped slope, and the fixing effect is achieved by utilizing frictional gripping force. The screw is composed of a screw and an expansion tube. When the nut is tightened, the screw moves, creating a significant positive pressure and achieving a fixing effect. Spring washers and flat washers respectively serve to prevent nut loosening and evenly distribute pressure.
Overview of specifications for stainless steel expansion bolts
The specifications of stainless steel expansion bolts include different grades and materials, and suitable specifications can be selected according to needs. Common specifications include 6 x 60, 6 x 80, 6 x 120, and 6 x 150.
Widely applicable
Due to its advantages, stainless steel expansion bolts are widely used in various decoration occasions, such as fastening air conditioners and fixing frameless balcony windows.
Tips for dealing with rust on stainless steel expansion bolts
Vibration: Gently shake the handle of the wrench with a hammer to unscrew the rusted bolts.
Knocking: Use a square headed hammer to tap the corroded nut at the edge to loosen it.
Barbecue: Use a gas welding oxidation flame to heat the screws, then add a little oil to make them expand and quickly shrink, making it easier to unscrew the nuts.
Welding: Weld an iron block onto a broken wire using electric welding, making it easier to unscrew the bolt.
Impact: Use a hammer and a turbine top screwdriver to impact a V-shaped groove at the top of the bolt, then impact along the direction of the bolt's rotation, and then use wire pliers to rotate the bolt out.
The above techniques can be selected and used according to specific situations to address the problem of stainless steel expansion bolts rusting.
