Grade 8.8 Partial Hex Socket Screws with Low Shank (Zinc/Black Oxide)

Engineered for maximum holding power and precision, these Grade 8.8 partial hex socket screws are manufactured from high-quality carbon steel. The 'partial hex' or 'low shank' design features a reduced diameter under the head, allowing the screw to seat flush against the mating surface while providing a larger bearing area for the head. This is critical in structural steel connections where surface flatness and load distribution are paramount.

Key Features & Benefits

• Grade 8.8 Strength: Heat-treated carbon steel ensures high tensile strength and excellent fatigue resistance, suitable for heavy-duty structural loads.
• Low Shank Design: The partial hex profile minimizes the height of the threaded section near the head, ensuring a tighter fit against flanges and structural beams.
• Durable Finish: Available with Zinc Plating for general corrosion protection or Black Oxide for a matte, low-glare finish that protects against rust in indoor or controlled environments.
• Socket Drive: The internal hex drive allows for high torque application with minimal risk of cam-out, ensuring a secure and tight joint.

Ideal for construction, machinery assembly, and industrial equipment where reliable fastening and space constraints are key considerations.
