Made of 304 stainless steel: The internal locking wire drawing rivets are constructed from 304 stainless steel, effectively addressing rust and corrosion concerns. The surface undergoes a whitewashing and polishing process for enhanced durability. High strength: Featuring high tensile and shear resistance, the internal locking wire drawing rivets boast a cup-type nail core locking force, with a minimum shear resistance of 1000KGF per rivet. Anti-vibration: Internal locking wire drawing rivets exhibit strong anti-vibration properties, exceptional sealing ability, and a waterproof function. Internal locking mechanism: Brushed rivets incorporate a structural design with an internal locking feature. This locking feature remains unseen when the rivet is applied. The mandrel is retained within the shear plane, providing high strength under shear loads, and the internal lock ensures positive mandrel retention, resulting in high strength under pullout loads. Versatile Applications: Whether you're involved in construction projects, automotive repairs, or general fabrication, these rivets offer versatility and adaptability. Trust in their ability to deliver exceptional performance across a wide range of applications. Easy to Install: Save time and effort with our user-friendly rivets. The installation process is straightforward, requiring only a regular rivet gun, making these fasteners suitable for both professionals and DIYers. Streamline your projects without compromising on quality.
