304 Stainless Steel Threaded Weldable Plates - Square

Upgrade your structural builds with our 304 Stainless Steel Threaded Weldable Plates – Square, premium weld-on base plates designed to create strong, corrosion-resistant threaded fixing points in square tube and box section frameworks. Perfect for heavy-duty fabrication, workshop projects, machinery assemblies, and adjustable support systems, these plates make installation fast, secure, and dependable.

Key Features & Benefits

Premium 304 Stainless Steel Construction: Made from high-quality 304 stainless steel — known for excellent corrosion resistance, strength, and durability — these plates are ideal for both indoor and outdoor environments, including wet, marine, or hygienic applications.

Threaded Weldable Design: Each square plate features a precision-cut threaded hole that can be welded directly into square steel tube or box section, providing a robust anchoring point for fasteners.

Versatile Thread Options: Available in a range of metric thread sizes (M8–M20) and plate dimensions (e.g., 25 × 25 mm, 30 × 30 mm, 40 × 40 mm, 50 × 50 mm), so you can choose the right plate for your tube size and hardware needs.

Heavy-Duty 3 mm Thickness: Designed with robust material thickness for excellent load distribution once welded in place, making them ideal for adjustable feet, levelling supports, castors, bolts and other fixings.

Easy Welding & Integration: These plates can be quickly welded into tube ends or frames, helping you create sturdy fixing points without complex machining or tapping operations.
