Description

Safety Locking Plate Type SIG

This SIG safety locking plate is a professional supporting accessory designed exclusively for AF series stacking bolts (hydraulic pipe clamps). It acts as an anti-loose locking spacer between stacked pipe clamps, effectively preventing bolt loosening caused by mechanical vibration, hydraulic impact and equipment operation shake, greatly improving the stability of multi-layer stacked pipe clamp assemblies.

Made of high-strength carbon steel with uniform galvanized surface treatment, this U-slot lock plate features precise stamping forming, smooth slot fit, and long-lasting rust resistance for industrial hydraulic systems, machinery, engineering vehicles and offshore equipment.

Features

Special Matching for AF Stacking Bolt
Dual U-shaped open slot design perfectly fits AF stacking bolts, easy to install between stacked pipe clamps without dismounting the whole pipeline.
Powerful Anti-Loosing & Anti-Vibration Performance
Creates locking friction between bolt and pipe clamp layers, eliminates loose risks from long-term equipment vibration, reduces pipeline maintenance frequency.
Precision Stamped & Smooth Edges
One-piece stamping molding, rounded edge design to avoid scratching bolt surfaces and pipe clamp coatings; tight dimensional tolerance for seamless assembly.
Galvanized Anti-Corrosion Surface Finish
Electro-galvanized coating resists oxidation, moisture and weak chemical corrosion, suitable for indoor workshops, outdoor machinery, humid coastal working environments.
Thin & Compact Structure
Ultra-thin flat plate design, no extra bulk to stacked pipe clamp groups, keeps neat pipeline layout while ensuring locking safety.
Full Size Compatibility
Supports all STAUFF/DIN standard pipe clamp groups (Group 1~8), matching all corresponding AF stacking bolt sizes; custom thickness & dimensions available.
