Hand Operated Quick Lock Pin for Welding Fixture

Push-type tool-free operation. Lock and release with simple press, enabling fast jig module assembly and shortening jig change-over time.

Flush countersunk-head design. Pin head fully sinks into hole without protrusion, avoiding collision interference and not affecting other jig layout on table surface.

Spring self-locking & vibration-resistant. Firm engagement after locking prevents loosening under welding vibration for stable jig connection.

High-strength hardened alloy-steel body. Excellent wear and impact resistance for frequent repeated plug-pull operations and long service life.

Wide hole-system compatibility. Fits D16 and D28 flexible welding tables for fast connection of angle rulers, clamping bridges, locating blocks and other jig modules.

Broad application scope. Suitable for prototype trial and mass production, widely used in sheet-metal, steel-structure, engineering machinery and new-energy frame welding.
