Hole-Hole Welding Table Clamping Square
Dual-face System · Precision Right Angle | Plug-and-Lock, No Welding Deviation Ever ->(Buy Now)
★Suitable for 2D/3D welding worktables (hole diameter 16mm or 28mm, customizable on demand), it is an ideal helper for heavy workpiece welding, mass production and high-precision assembly.
Product Overview

Precision starts with angles.
The Hole-Hole Welding Table Clamping Square is a precision right-angle positioning tool specially designed for perforated welding worktables. The model 175x50x175 (Hole/Hole) indicates that the height of both vertical sides is 175mm, the length of the base/thickness direction is 50mm, and positioning holes with standard aperture sizes are prefabricated on both vertical surfaces.
Different from traditional L-shaped try squares, this clamping square features a **double-sided hole design**. It can be firmly fixed to the workbench hole system via pins or quick clamps, and accurately positions the workpiece from two perpendicular directions. It solves the problem of "right-angle displacement" caused by vibration or thrust during welding and assembly, turning 90° positioning from "repeated measurement" into "plug-and-precise alignment".

Products Advantages
Advantages and Features
1. **Double-sided Structural Design**
Positioning holes are drilled on both vertical planes. It can be fixed on the workbench with pins, and workpieces can also be clamped from two directions by perforated fixtures, preventing long-arm workpieces from offsetting due to thermal deformation.
2. **Precise 90° Without Repeated Alignment**
With grinding processing and CMM inspection, the right angle accuracy is ≤0.05mm/100mm. Perpendicularity can be ensured in one clamping, reducing measurement time.
3. **Fast Clamping Compatible with Mainstream Workbenches**
Compatible with positioning pins, screw clamps and quick locking pins. Connection to the welding table can be completed within seconds, and it can be combined with other modules on the tabletop.
4. **Resistance to Welding Spatter and Deformation**
Adopting a thick-wall design (key parts ≥12mm). The surface can be treated with anti-spatter coating or nitriding. Welding slag can be easily knocked off, maintaining long-term precision.
5. **Bilateral Symmetrical Design for Left and Right Hand Use**
No need to distinguish installation directions. It is flexibly applicable to various weld types such as inner and outer corners, T-joints and lap joints.
Products Application

Scope of Application
• Ship/Vehicle Welding Fixtures: Quickly construct right-angle structures such as exhaust pipes, vehicle frames and railings.
• Steel Structure & Metal Furniture: Mass-produce table legs, storage shelves and equipment supports.
• Pipe Flange Assembly: Ensure the flange face is perpendicular to the pipeline.
• Educational Training Platforms: Enable students to quickly understand the principles of right-angle positioning and tooling fixtures.
• On-site Maintenance & Modification: Perform precise repair and fitting of non-standard parts on the welding table.
