1/3Square / T-Head Bolt
Designed for aluminum extrusions, channel tracks, and machinery mounting slots, our Class 8.8 Yellow Zinc-Plated Square T-Head Bolts offer exceptional clamping stability and anti-twist performance. The flattened square head slides smoothly into standard aluminum profiles and T-slots, locking into place to prevent rotation during tightening. Treated with a vibrant yellow zinc dichromate coating, this fastener delivers high tensile strength alongside superior rust and corrosion resistance.

Product description
Class 8.8 Yellow Zinc-Plated Square T-Head Slot Bolt
- Class 8.8 High Strength: Explicitly stamped with the 8.8 performance grade mark on the top surface, ensuring reliable tensile strength and high yield capacity for medium-to-heavy industrial loads.
- Square T-Slot Head Design: Features a flat, low-profile square head specifically engineered to seat flush inside standard aluminum extrusion slots, strut channels, and machine beds, preventing independent bolt rotation.
- Yellow Zinc Surface Finish: Coated with high-grade yellow zinc dichromate plating, providing robust protection against humidity, oxidation, and harsh environmental wear while giving a distinct iridescent metallic aesthetic.
- Precision Metric Threading: Fully threaded shaft with uniform, smooth-running metric threads ensures optimal thread engagement, high torque tolerance, and secure clamping force.
- Durable Carbon Steel Construction: Drop-forged from quality carbon steel and heat-treated to achieve superior shear strength and structural fatigue resistance.
- Versatile Applications: Widely used in modular aluminum framing systems, solar panel mounting hardware, CNC machinery assembly, industrial conveyor tracks, and heavy-duty structural framing.
