Aluminium Drop-in T Nut for T Slot Aluminium Profile Connection
As a leading aluminum profile manufacturer, we present our Aluminium Drop-in T Nut, precision-engineered for seamless T-slot connections. These high-strength fasteners are designed for quick, tool-free installation into aluminum extrusion channels, ensuring secure and adjustable joints. Made from durable carbon steel (galvanized) or stainless steel, they offer excellent corrosion resistance and load-bearing capacity. Our drop-in T nuts are available in multiple thread sizes (M4, M5, M6, M8) and slot widths (6mm, 8mm, 10mm), with various lengths to suit different profile depths. Ideal for industrial framing, machine guards, workstations, and DIY projects, they provide reliable, reconfigurable connections without damaging the profile surface. Trust our factory-direct quality for consistent performance and easy assembly.
Frequently Asked Questions
- What materials are available for these T nuts? We offer two material options: carbon steel with galvanized finish (C) for general use, and stainless steel (SS) for enhanced corrosion resistance in harsh environments.
- What thread sizes and slot widths do you support? Our drop-in T nuts come in thread sizes M4, M5, M6, and M8, compatible with 6mm, 8mm, and 10mm T-slot widths. Lengths vary from 20mm to 45mm depending on the model.
- How do I select the correct part number? Use the format MKTSF-HHN-C(SS)-[thread]-[slot width]-[length]. For example, MKTSF-HHN-C-M5-6-20 is a carbon steel M5 nut for 6mm slots, 20mm long. Contact us for custom specifications.
