Our weld-on indexing plungers are heavy-duty, spring-loaded positioning components designed for permanent integration into steel frameworks, square tubing, and metal plates. Unlike threaded plungers, these feature a smooth weldable sleeve, allowing them to be directly welded onto machinery and structural setups, providing an exceptionally solid, wobble-free locking and alignment point.
They are widely used in heavy-duty industrial and construction fields:
Agricultural & Forestry Machinery: Used for securing adjustable arms, sliding booms, and folding sections on heavy tractors or harvesters.
Specialty Vehicles & Trailer Gates: Ideal for locking and securing dump trailer gates, ramps, and heavy-duty sliding compartments.
Construction & Demolition Equipment: Provides reliable locking for steel scaffolding systems, modular formworks, and telescoping booms.
Custom Metal Fabrication & Material Handling: Used on warehouse racking systems, heavy-duty rotating fixtures, and steel workstations where high vibration resistance is required.
Weldable Steel Sleeve (Grade 1.0403/1.4301): The outer body is made from weldable carbon steel or weldable stainless steel (optional), ensuring ease of welding without compromising the structural integrity of the base frame.
Ergonomic Pull Ring Design: Equipped with a rugged, heavy-duty loop pull ring that allows for rapid retraction of the locking pin with a single finger—even while wearing heavy welding gloves.
Heavy-Duty Shear Strength: Built with a precision-ground, hardened indexing pin designed to withstand massive shear and radial loads without bending or deformation.
Thermal-Protected Spring Chamber: Designed with sufficient internal clearance so that the high-tensile spring is protected from heat damage during professional tack-welding installation.
Optional Lock-Out Position: Available in both spring-return (retracts when released) and lock-out (pull and rotate to keep the pin in the retracted state) configurations.
We are a direct source manufacturer with over 10 years of professional CNC machining and metal fabrication experience.
Direct-from-Factory Pricing: Bypass intermediate trade distributors and brokers. Buy directly from our production line to optimize your procurement costs and boost your margins.
Full OEM/ODM Customization: We can manufacture weldable plungers to your precise drawings. Customize pin diameters (M8 to M24), pin lengths, internal spring loads, custom materials (e.g., 316 Stainless Steel), or specific ring sizes.
Precise Tolerances & Integrity: Equipped with advanced CNC turning-milling centers and precise grinding machinery, we ensure the indexing pin diameter and coaxial tolerance are strictly maintained for flawless fits.
Rigorous Structural Testing: Every production batch undergoes shear load tests, spring cycle endurance tests, and material analysis to guarantee maximum safety and durability in harsh outdoor environments.
