Product Overview:
The DK633-1 Slide Latch is a heavy-duty fastening solution engineered for secure and reliable locking of industrial doors, cabinets, and metal enclosures. With a 70mm base length, 40mm width, and a robust sliding bolt mechanism, this latch ensures a tight and secure hold. The DK633-1 Slide Latch is available in three material configurations to suit various environmental and budget requirements: the standard DK633-1 (steel body with a SUS304 stainless steel bolt), the DK633-1F (full steel), and the DK633-1S (full SUS304 stainless steel).

Material Options for Every Application:

  • DK633-1 (Steel body, SUS304 bolt): Combines a durable zinc-plated steel base with a corrosion-resistant SUS304 stainless steel bolt. Ideal for general industrial use where the sliding mechanism requires extra rust protection.

  • DK633-1F (Full Steel): A cost-effective, all-steel construction with a zinc-plated finish. Best suited for indoor applications and controlled environments.

  • DK633-1S (Full SUS304): Premium 100% SUS304 stainless steel with a grinding finish. Offers maximum corrosion resistance for marine, chemical, and outdoor environments.

Key Features & Benefits:

  • M5 Rivet Nut for Easy Automation: The tail end of the latch features an M5 rivet nut. This allows for quick and secure attachment of a handle, push rod, or linkage, making it highly adaptable for automated systems or custom manual operations.

  • Heavy-Duty Slide Mechanism: The 103mm total length and robust sliding bolt provide a secure engagement, ensuring doors remain locked under heavy vibration or impact.

  • White Cushioning Head: The sliding bolt is equipped with a white cushioning head, reducing noise and impact when the latch is operated, and preventing damage to the receiving strike plate.

  • Precision Mounting: The base features 4 x Ø4.5mm mounting holes spaced at 40±0.5mm, providing a stable and precise installation on flat surfaces.

Application Guide:
The DK633-1 Slide Latch is the definitive choice for:

  • Industrial Control Cabinets: Secure electrical panels and server racks.

  • Heavy Machinery Enclosures: Engine covers, access doors, and maintenance panels.

  • Marine & Outdoor Enclosures: The SUS304 version (DK633-1S) withstands saltwater and harsh weather conditions.

  • Transportation: Truck toolboxes, RV compartments, and train interiors.

  • Metal Doors & Gates: A reliable sliding bolt mechanism for secondary security.

Installation and Maintenance:
Installation is straightforward: mount the latch base using the 4 x Ø4.5mm holes and appropriate bolts. Align the sliding bolt with the receiving hole or strike plate. If desired, attach a custom handle or rod to the M5 rivet nut at the rear. The zinc-plated and stainless steel surfaces require minimal maintenance—simply wipe with a damp cloth to remove dust or dirt. Regular inspection of the mounting screws is recommended for high-vibration applications.

Frequently Asked Questions (FAQ):

  • Q: What is the difference between DK633-1, DK633-1F, and DK633-1S?
    A: DK633-1 has a steel body with a SUS304 bolt. DK633-1F is fully steel (zinc plated). DK633-1S is fully SUS304 stainless steel (grinding finish).

  • Q: What is the purpose of the M5 rivet nut?
    A: The M5 rivet nut at the tail of the latch allows you to easily attach a handle, push rod, or mechanical linkage for operation.
