Rotation Angle Square – 28mm System

Create adjustable fixturing angles for setups that a standard fixed square cannot reach.
SHT-T28-32810 Rotation Angle Square is designed for 28mm welding table systems and provides up to 180° of adjustable rotation. The rotating design allows you to position clamps and fixturing components at virtually any angle within its adjustment range, making it useful for angled parts, unusual assemblies, and hard-to-reach clamping locations.

The SHT-T28-32810 features 28mm fixture holes on a 50mm grid pattern and is designed for use with compatible fast-clamping bolts and 28mm welding table systems.

Why Choose a Rotation Angle Square?

• 180° Adjustable Rotation: Position the upright fixture through a wide range of angles instead of being limited to a fixed 90° setup.
• Flexible Clamping Positions: Helps position clamps and accessories for angled or hard-to-reach workpieces.
• 28mm Fixturing System: Designed around 28mm diameter fixture holes.
• 50mm Grid Pattern: Hole spacing matches compatible 28mm fixturing systems.
• Multiple Configurations: Can be positioned and used in different orientations to match the job.
• 1045 Steel Construction: Built from durable 1045 steel.
• Nitrided Finish: Nitrided surface treatment provides a durable working surface for shop use.

Adjust the Fixture to the Job

A traditional angle square locks your setup into one fixed angle. The SHT-T28-32810 adds a rotating joint that allows the upright fixturing plate to be adjusted through an angle range of 180°.

This gives you more freedom when positioning parts that are not square to the table. Once the desired angle is established, compatible 28mm fixturing components can be used to secure the setup.

Common Applications

• Angled welding fixtures
• Custom fabrication setups
• Positioning parts at non-90° angles
• Holding irregular assemblies
• Hard-to-reach clamping positions
• Temporary welding fixtures
• Repeatable fabrication setups
• 28mm welding table fixturing

Multi-Position Fixturing

The combination of the rotating base and multiple 28mm system holes gives you several ways to position clamps, stops, and other compatible fixturing components.

Instead of building a separate fixture every time a part requires an unusual angle, the Rotation Angle Square can be repositioned to match the workpiece and then reused for the next setup.

Frequently Asked Questions

What does the Rotation Angle Square do?
It provides an adjustable upright fixturing surface that can be rotated through a 180° range, allowing clamps and workpieces to be positioned at angles that would be difficult to achieve with a fixed square.

How far can the angle square rotate?
The SHT-T28-32810 provides an 180° angle adjustment range.

What size welding table system does it fit?
It is designed for compatible 28mm welding table systems.

What size are the fixture holes?
The holes are 28mm (1.1") in diameter.

What is the hole spacing?
The fixture uses a 50mm (2.0") grid pattern.

What material is the angle square made from?
The SHT-T28-32810 is manufactured from 1045 steel with a nitrided finish.

How tall is it?
The overall height is approximately 275mm (10.8").

What size is the base?
The base measures approximately 249mm x 180mm (9.8" x 7.1").

Is this just for 90° setups?
No. The main advantage of this fixture is its adjustable design. The upright can be positioned through a 180° rotation range for a variety of angled fixturing setups.
