1. Exposed Fracture: Directly Clamp and Remove If part of the screw is still exposed after breakage: Use needle-nose pliers or diagonal pliers to clam

1. Assess the extent of stripping and clean the screw hole. If the stripping is minor, use compressed air or a fine brush to remove metal debris, oil,

1. Risks of using stripped screws: Insufficient tightening force: Stripped screws have deformed or missing threads, preventing them from forming a com

1. Clean and Prepare the Hole Use compressed air or a fine brush to remove metal shavings, oil, and residue from the hole to ensure smooth tapping. If

1. Slight Stripping: Increase Friction to Try Unscrewing If the screw head and slot are only slightly worn, try the following methods to increase grip

1. Visual Inspection: Check Thread Integrity Carefully examine the threaded portion of the self-tapping screw. If there is obvious wear, deformation,

First, check the fit between the screw head and the connected component. Ideally, the screw head should be fully against the surface, without any gaps

1. Loosening or detachment: When screws are not tightened properly, insufficient preload prevents adequate clamping force, causing the connected parts

Flange nuts usually need to be retightened after installation, especially under high temperature, high pressure, or vibration conditions. Retightening

1. Electroplating (Zinc Plating) A layer of zinc is deposited on the nut surface through electrolysis, utilizing zinc's sacrificial anode effect t

1. Check the Environmental Corrosion Level: Is it Corrosion-Proof? Low-Corrosion Environment (Dry Indoors): If the nut is used in water-free and salt-

1. Ordinary Indoor Environment (Low Corrosion) Suitable for dry environments without chemical exposure, such as office equipment, furniture, and gener
