Anti-collision rubber handwheel Insulated screw protection cap Moisture-and-dust-proof rubber handwheel

Rubber thread protection caps are a category of protective fittings with rubber as the core material, specifically designed for threaded components like screws, bolts, and studs. They deliver multiple forms of protection through physical isolation:

Anti-corrosion & anti-rust: Isolating air, moisture, and dust to prevent threaded parts from rusting due to oxidation or humidity.

Anti-physical damage: Cushioning impacts to avoid thread deformation during transportation and installation.

Process compatibility: When electroplating, painting, or sandblasting, covering threads prevents coatings from adhering, ensuring connection precision.
