Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Positioning and Secure Locking: Designed to provide reliable mechanical retention and alignment in machinery, using fine-thread screws and indexing plungers for exact positioning.
  • Toggle Activation Mechanism: Features a tactile on/off switch (red dial) for quick operation, enabling users to engage or disengage the locking mechanism with ease.

Key features

  • 1. Corrosion-Resistant Material Technology

  • With corrosion-resistant stainless steel construction, ensure durability in harsh industrial environments. The polished surface treatment enhances resistance to rust and wear compared to standard steel bolts*.

  • 2. Customizable Interactive Design

  • With customizable mounting options via threaded holes, adapt to diverse equipment configurations more flexibly than fixed designs. The high-visibility red dial enables quick on/off identification in low-light settings, improving operational efficiency*.

  • 3. Precision Performance Parameters

  • With precision m1.6 threading and 15mm length, achieve secure fastening in tight spaces, offering 30% more adjustability than shorter bolts. The 6mm thickness ensures robust load-bearing capacity for heavy-duty applications*.

  • 4. Industrial Scenario Solutions

  • Designed for heavy-duty machinery, these plungers provide reliable positioning under constant operation in industrial settings. The shoulder washer and fine thread screw ensure stability in environments where standard bolts might loosen or fail*.

  • 5. Certified Environmental and Quality Standards

  • ISO 8749 compliance and EPR certifications (Germany/France/Spain) guarantee adherence to environmental and safety regulations, exceeding basic requirements for eco-friendly and durable fasteners*.
