Product Description

Countersunk Torx Countersunk Screws ® (Socket Head Screws)

1. Head Design: Integrated Plum Blossom Sinking Head

Countersunk: With a precisely engineered head cone angle of 82°, conforming to the ISO 2009 standard, these screws ensure flawless flush integration into surfaces upon installation. Perfect for scenarios demanding supreme flatness, such as the assembly of sleek furniture panels or the enclosures of sophisticated electronic devices.

• Plum Blossom Trough (Torx) ®/ Star Groove: This innovative hexagonal star groove design propels torque transmission to new heights with specialized batch heads, including the versatile T15-T30 specifications. Bolstered by an impressive anti-slip capability, surpassing cross grooves by over 70%, it is an excellent choice for high-speed electric tool installations with recommended speeds up to 3000 RPM.

2. Thread and Stem Characteristics

• Thread Type:

Self-Tapping Thread (ST Series): Equipped with a sharp cutting edge at the tip, it effortlessly pierces through cork or thin metal plates (such as aluminum alloys up to 3mm thick) without necessitating pre-drilling, ensuring swift and efficient installation.

Machine Thread (M Series): Designed for use with pre-drilled holes and nuts, this thread type is indispensable for high-load scenarios, such as in the robust connections of steel structures.

• Rod Material and Coating:

Carbon Steel (10B21/45# steel): Post heat treatment, it attains a hardness of HRC38-42, making it ideal for indoor applications under normal load conditions.

Stainless Steel (304/316): Offers exceptional corrosion resistance, rendering it perfectly suited for outdoor environments or areas with high humidity, such as maritime equipment and poolside accessories.

• Surface Coating:

Galvanized (Blue White/Color Zinc): Withstands salt spray tests of 72 hours or more, fulfilling general industrial rust prevention standards with ease.

Dakro: Endures salt spray for an impressive 500 hours or more, making it exceptionally suitable for coastal regions or chemically corrosive environments.
