T-Slot Bolts and Nuts for Aluminum Profiles
T-slot bolts and flange nuts provide a simple, reliable connection for modular aluminum extrusion frames. The T-shaped bolt head slides into the profile slot and locks against the internal shoulders when tightened, making it suitable for brackets, plates, hinges, feet, guards and other accessories.

How T-Slot Fasteners Work
The bolt head is inserted into the open profile slot or loaded from the extrusion end. When the flange nut is tightened, the head seats against the slot shoulders and creates a secure clamping connection. The joint can be loosened and repositioned without drilling or welding the profile.
Choosing the Correct Size
- Match the T-head dimensions to the extrusion slot width and internal geometry.
- Select the thread size according to the bracket hole and required clamping force.
- Choose a bolt length that provides full nut engagement without interfering with nearby components.
- Use stainless steel for environments requiring increased corrosion resistance.
- Confirm strength grade and coating when the joint carries structural or dynamic loads.
Applications
These fasteners are commonly used for machine frames, workbenches, safety guards, conveyor supports, robot enclosures, sensor mounts, leveling feet, hinges, handles, panel brackets and other modular T-slot assemblies.

Quality and Ordering
Please provide the extrusion series, slot dimensions, bolt length, thread size, material, strength grade, finish and quantity. Samples or dimensional drawings can be reviewed when slot compatibility is uncertain. Fasteners are inspected for thread quality, dimensions, surface condition and matching nut fit.
Frequently Asked Questions
Will these bolts fit every T-slot profile?
No. Slot width and internal profile geometry vary by extrusion series. Please confirm the slot drawing or provide a profile sample.
Can I order stainless steel fasteners?
Yes. Stainless steel options can be discussed, including A2 and A4 grades, depending on size and quantity.
Can the finish be customized?
Yes. Zinc plating, black oxide, chrome plating, nickel plating and other finishes can be reviewed for volume orders.
