Product Overview
The T-Nut, commonly known as a T-Slot Nut, is a specialized sliding fastener designed to be inserted and secured within the T-shaped channel of aluminum extrusions, machine tool tables, and modular framing systems. Its low-profile, rectangular body slides freely along the length of the slot, allowing for infinite positional adjustment. When tightened with a standard bolt or screw, it rotates 90 degrees, securely locking against the underside of the slot to create a strong, reliable, and repositionable connection point. It is the fundamental component for building adjustable structures, workholding fixtures, and automation equipment.
Key Advantages
Infinite Adjustability: Slides effortlessly within the T-slot before tightening, enabling precise, flexible, and tool-less positioning along the entire length of the extrusion.
Secure Locking Mechanism: The unique design allows the nut to be inserted into the slot and then rotated, causing its wings to engage firmly with the undercut of the slot, preventing pull-out.
Low Profile Design: Sits flush within the slot, preserving the clean lines of the extrusion and not interfering with adjacent components.
High Load Capacity: The large bearing surface area of the nut body distributes clamping forces effectively, making it suitable for structural applications.
Reusability & Flexibility: Can be easily loosened, repositioned, and retightened, allowing for fast reconfiguration of modular systems without damaging the extrusion.
Material Specifications & Grades
| Material | Standard / Grade | Characteristics & Best Use |
|---|---|---|
| Low Carbon Steel | ASTM AISI 1008/1010 | Economical, strong, suitable for most indoor industrial applications. Typically plated. |
| Medium Carbon Steel (Quenched & Tempered) | Grade 8.8 | Higher strength for demanding mechanical and structural clamping applications. |
| Stainless Steel | AISI 304 (A2) / 316 (A4) | Excellent corrosion resistance for harsh environments (chemical, food, marine, outdoor). |
| Aluminum Alloy | 6061-T6 | Lightweight, non-magnetic, and corrosion-resistant. Ideal for cleanrooms and specialty frames. |
Product Series & Dimensional Standards
Standard T-Nuts: Designed for industry-standard T-slot sizes (e.g., 6mm, 8mm, 10mm, 1/2″, 5/8″ series). Dimensional compliance ensures smooth operation within corresponding extrusions.
Heavy-Duty T-Nuts: Feature a thicker body and larger engagement surface for higher load requirements.
Spring-Loaded T-Nuts: Incorporate a spring to hold the nut in position within the slot prior to tightening, preventing it from falling out during vertical or overhead assembly.
Thread Sizes: Available in a wide range to match common bolt sizes. Metric: M4, M5, M6, M8, M10, etc. Imperial: #8-32, 1/4″-20, 5/16″-18, 3/8″-16, 1/2″-13, etc.
Available Surface Finishes
| Finish Type | Specification / Process | Primary Benefit |
|---|---|---|
| Electro-Zinc Plated (Blue/Trivalent Clear) | ASTM B633 | Standard, cost-effective corrosion protection for general use. RoHS compliant. |
| Yellow Zinc Plated | ASTM B633 | Enhanced corrosion resistance and distinctive appearance compared to blue zinc. |
| Black Oxide/Phosphate | MIL-DTL-13924 | Good wear resistance, reduces light glare, and provides a non-reflective surface. |
| Nickel Plated | ASTM B456 | Good corrosion and wear resistance with a bright, silvery appearance. |
| Passivation (Stainless Steel) | ASTM A967 | Enhances the natural corrosion resistance of stainless steel without altering dimensions. |
Typical Applications
80/20 Style Aluminum Framing: The primary fastener for constructing machine guards, workstations, enclosures, and automation frames.
Machine Tool Tables: For securing workpieces, vises, and fixtures to milling machine and CNC tables with T-slots.
Industrial Automation: Building adjustable sensor mounts, conveyor guides, and guarding systems.
Retail & Display: Assembling modular shelving, kiosks, and exhibition structures.
Furniture & Ergonomics: Constructing adjustable-height desks, technical furniture, and ergonomic supports.
Quality Assurance
Our T-Nuts are manufactured under a certified ISO 9001:2015 quality management system. Production includes strict dimensional control to ensure precise fit within standard T-slots, thread gauging for proper engagement, and material verification. Batch consistency is a priority for reliable assembly performance.
