Dacromet Triangle Lock Self-Tapping Screw GB6560
Dacromet triangle lock self-tapping screw GB6560 is a high-performance fastening component designed for applications requiring strong thread locking ability, vibration resistance, and superior corrosion protection. The Dacromet triangle lock self-tapping screw GB6560 combines a special triangle thread forming structure with a Dacromet coated carbon steel body, providing reliable fastening performance in demanding industrial environments.
The Dacromet triangle lock self-tapping screw GB6560 forms strong internal threads through material displacement during installation, while the triangular thread profile improves anti-loosening performance and connection stability. It is widely used in automotive manufacturing, machinery, electrical equipment, industrial assemblies, and OEM applications.
Product Overview
The Dacromet triangle lock self-tapping screw GB6560 is a specialized thread forming fastener manufactured according to GB6560 requirements. Unlike conventional tapping screws, this screw uses a triangular locking thread design that generates radial pressure between the screw and the mating material, improving resistance against loosening caused by vibration.
The Dacromet coating provides excellent corrosion resistance without introducing hydrogen embrittlement risks commonly associated with some electroplating processes. This makes the Dacromet triangle lock self-tapping screw GB6560 suitable for automotive and industrial applications requiring long-term durability.
The thread forming structure reduces cutting debris, improves thread engagement, and supports efficient automated assembly.
