Aluminum Sliding Nut — Flexible Fixing for Every Rail Position

Description

Extruded aluminum sliding nut (T-nut) for solar mounting rails. Slides into any channel position for tool-free adjustment; complete assembly with A2-70 stainless socket head cap screw, spring washer, and flat washer. Ideal for end clamps, mid-clamps, and grounding lugs. Factory direct.

Overview

The aluminum sliding nut is the universal fixing component for solar mounting rails. Its T-shaped extruded aluminum profile slides smoothly into the rail channel and can be positioned anywhere along the rail before tightening — giving installers complete flexibility for clamps, brackets, and accessories without pre-drilling or alignment issues.

Each assembly includes an A2-70 stainless steel socket head cap screw with a knurled head, a spring washer, and a flat washer, providing a secure, vibration-resistant fastening. The sliding nut is widely used with end clamps, mid-clamps, grounding lugs, and other rail-mounted components, making it an essential accessory for any PV mounting system.
